本发明涉及通信领域，尤其涉及一种检测报文染色位冲突的方法和设备。The invention relates to the field of communication, in particular to a method and equipment for detecting message dyeing bit conflicts.
背景技术Background technique
网际协议(Internet Protocol，IP)流性能测量(Flow PerformanceMeasurement，FPM)是一种对目标报文性能直接测量的技术手段。IP FPM通过对目标报文直接测量，可以得到网络中目标报文的真实丢包统计和时延统计等性能指标。IP FPM染色位是IP FPM技术正常测量统计的核心，IP FPM染色位是指入口节点对目标报文进行周期性的识别、染色的比特位，在目标报文途经的节点及出口节点对染色报文进行识别和统计，并根据各节点的统计数值及时间戳在沿途各节点的变化情况计算目标报文的丢包和时延。IPFPM染色位包括服务类型(Type of Service，ToS)字段的第3比特位至第7比特位和标记(Flag)字段的第0比特位。在IP FPM检测时，如果目标报文的染色位与目标报文的其它业务存在冲突，不仅会造成IP FPM丢包和时延统计结果出错，还将影响冲突业务报文的转发。Internet Protocol (Internet Protocol, IP) Flow Performance Measurement (Flow Performance Measurement, FPM) is a technical means for directly measuring the performance of target packets. Through direct measurement of target packets, IP FPM can obtain performance indicators such as actual packet loss statistics and delay statistics of target packets in the network. The IP FPM coloring bit is the core of the normal measurement and statistics of the IP FPM technology. The IP FPM coloring bit refers to the bit that the ingress node periodically identifies and dyes the target packet. The packets are identified and counted, and the packet loss and delay of the target packet are calculated according to the statistical value of each node and the change of the time stamp at each node along the way. The IPFPM coloring bits include bit 3 to bit 7 of the type of service (Type of Service, ToS) field and bit 0 of the flag (Flag) field. During IP FPM detection, if the dyed bit of the target packet conflicts with other services of the target packet, it will not only cause IP FPM packet loss and delay statistics to be wrong, but also affect the forwarding of conflicting service packets.

具体实施方式Detailed ways
下面结合附图，对本发明的实施例进行描述。Embodiments of the present invention will be described below in conjunction with the accompanying drawings.
本申请实施例中，染色位是指对目标报文进行特征标识的比特位。在进行报文流的性能测量时，例如在进行IP FPM检测时，入口节点通过对报文的染色位进行周期性的特征标识来测量目标报文的丢包统计和时延统计。通常情况下，IP FPM检测的染色位为报文中实际使用较少比特位，例如某些字段的预留位或预留字段中的比特位，本申请实施例以IP FPM检测的染色位包括目标报文的服务类型字段的第3比特位至第7比特位和标记字段的第0比特位，共6个染色位为例进行说明。IP FPM是一种可以对目标报文进行直接检测的技术手段。IP FPM的完整检测流程包括：用户通过指定入口节点及出口节点、目标检测报文的IP五元组信息，以确定需要检测的目标报文、目标路径。网络控制设备根据识别的路径生成需要下发给入口节点和出口节点的配置信息，并在目标流流经的各个节点上配置检测点、检测动作、报文识别规则，确保检测点能够按照方案设定动作进行检测。最后，各检测点上报检测数据，并在数据收集节点进行计算将最终结果呈现给用户。需要说明的是，此处仅以IP FPM检测中的丢包统计和时延统计为例说明，本发明并不限于此，其他采用染色方式进行丢包统计、时延统计或者其他类似统计时会与目标报文的其它业务产生于冲突的能够采用本发明中实施例解决的都在本发明的范围内。In the embodiment of the present application, the coloring bit refers to a bit for characteristic identification of the target packet. When performing packet flow performance measurement, for example, when performing IP FPM detection, the ingress node measures packet loss statistics and delay statistics of target packets by performing periodic feature identification on the dyed bits of the packets. Normally, the colored bits detected by IP FPM are the bits actually used in the message, such as reserved bits of certain fields or bits in reserved fields. In the embodiment of this application, the colored bits detected by IP FPM include The 3rd to 7th bits of the service type field of the target message and the 0th bit of the flag field, a total of 6 colored bits are used as an example for illustration. IP FPM is a technical means that can directly detect target packets. The complete detection process of IP FPM includes: the user determines the target packet and target path to be detected by specifying the entry node and exit node, and the IP quintuple information of the target detection packet. The network control device generates configuration information that needs to be delivered to the ingress node and the egress node according to the identified path, and configures detection points, detection actions, and message identification rules on each node that the target flow passes through to ensure that the detection points can be set according to the plan. Check the action. Finally, each detection point reports the detection data, and calculates at the data collection node to present the final result to the user. It should be noted that, here, the packet loss statistics and delay statistics in IP FPM detection are only used as an example for illustration, and the present invention is not limited thereto, other methods of coloring for packet loss statistics, delay statistics or other similar statistics will Conflicts with other services of the target message that can be resolved by using the embodiments of the present invention are within the scope of the present invention.
在上述报文流量性能检测过程中，如果目标报文测量时延使用的染色位与目标报文其它业务的比特位相同时，目标报文的染色位与目标报文的其它业务发生冲突。需要说明的是，这里所说其它业务广泛地包括利用该报文的该比特位所进行的除了上述用染色位进行流量性能检测业务之外的各类业务。这种冲突不仅会造成报文流量性能的检测结果出现错误，还会对目标报文的正常转发产生影响。例如，报文的标记字段的第0比特位已经被用来标识指导目标报文转发的优先级业务，在这种情况下如果将上述标记字段的第0比特位强制进行配置并进行报文流量性能检测目标报文的丢包统计，则不仅会更改目标报文的优先级导致该目标报文在转发过程中被丢弃，还可能造成目标报文丢包统计的错误。In the above packet flow performance detection process, if the coloring bits used to measure the delay of the target message are the same as the bits of other services of the target message, the coloring bits of the target message conflict with other services of the target message. It should be noted that the other services mentioned here broadly include all kinds of services performed by using the bit of the message except the above-mentioned traffic performance detection service using the dyed bit. Such conflicts will not only cause errors in the detection results of packet traffic performance, but also affect the normal forwarding of target packets. For example, the 0th bit of the tag field of the message has been used to identify the priority service that guides the forwarding of the target message. In this case, if the 0th bit of the above tag field is forcibly configured and The packet loss statistics of the performance detection target packet will not only change the priority of the target packet and cause the target packet to be discarded during the forwarding process, but may also cause errors in the packet loss statistics of the target packet.
为解决上述问题，图1为本申请实施例提供了一种应用场景示意图。在利用报文的染色位进行报文流量性能检测之前，例如报文的丢包统计或时延统计之前，需要控制设备104对目标报文的待染色位进行检测，确定是否存在用于报文流量性能检测的染色位与报文的其它业务冲突，如果存在冲突，则不用该染色位进行报文流量性能的检测，如果不存在冲突，则用该染色位进行报文流量性能的检测，从而可以提高报文流量性能的准确度，并且不影响报文的其他业务。例如，显示拥塞控制通告业务需要使用目标报文ToS字段的第6比特位和第7比特位进行标记，如果目标报文流性能测量的染色位与所述显示拥塞控制通告业务标识的比特位发生冲突，则不仅会造成报文时延测量出现错误，而且还会影响目标报文显示拥塞控制通告业务。因此为了确保报文流性能检测的正确性，避免与业务报文转发中使用的染色位发生冲突，需要在进行报文流性能检测之前对判断染色位是否与该报文的其它业务存在冲突。To solve the above problem, FIG. 1 provides a schematic diagram of an application scenario according to an embodiment of the present application. Before using the dyed bit of the message to perform packet traffic performance detection, such as packet loss statistics or delay statistics of the packet, it is necessary for the control device 104 to detect the to-be-colored bit of the target packet to determine whether there is a The dyed bit of traffic performance detection conflicts with other services of the packet. If there is a conflict, the dyed bit is not used to detect the packet traffic performance. If there is no conflict, the dyed bit is used to detect the packet traffic performance, thereby The accuracy of packet traffic performance can be improved without affecting other services of packets. For example, the display congestion control notification service needs to be marked with the 6th bit and the 7th bit of the ToS field of the target packet. If there is a conflict, it will not only cause an error in the packet delay measurement, but also affect the target packet display congestion control notification service. Therefore, in order to ensure the correctness of packet flow performance detection and avoid conflicts with the dyed bits used in service packet forwarding, it is necessary to determine whether the dyed bits conflict with other services of the packet before performing packet flow performance detection.
图1中的控制设备104可以是软件定义网络(Software-Defined Networking，SDN)控制器，也可以是测量控制设备。在控制设备104向入口节点101和出口节点103下发报文染色位配置信息以测量报文时延之前，先判断待染色比特位是否与所述报文的其它业务存在冲突。在确定待染色位与所述报文中的其它业务没有冲突的情况下，控制设备104将该染色位的配置信息下发给入口节点101和出口节点103，以进行报文流性能检测。The control device 104 in FIG. 1 may be a software-defined network (Software-Defined Networking, SDN) controller, or may be a measurement control device. Before the control device 104 sends message coloring bit configuration information to the ingress node 101 and the egress node 103 to measure the message delay, it first judges whether the bits to be dyed conflict with other services of the message. When it is determined that the bit to be dyed does not conflict with other services in the message, the control device 104 sends the configuration information of the dyed bit to the ingress node 101 and the egress node 103 to perform packet flow performance detection.
图1中的网络102可以是IP协议的网络，也可以是包括多协议标签交换(Multi-Protocol Label Switching，MPLS)的网络。The network 102 in FIG. 1 may be an IP protocol network, or a network including Multi-Protocol Label Switching (Multi-Protocol Label Switching, MPLS).
图1中的入口节点101和出口节点103是报文流性能测量路径的入口节点和出口节点。本申请实施例中，“节点”可以指在网络中对业务流量进行转发的设备，比如“节点”可以是路由器、交换机、光传送网(英文：Optical Transport Network，简称：OTN)设备、分组传送网(英文：Packet Transport Network，简称：PTN)设备或者波分复用(英文：WavelengthDivision Multiplexing，简称：WDM)设备。举例来说，入口节点和出口节点可以是转发报文的路由器。The ingress node 101 and the egress node 103 in FIG. 1 are the ingress node and the egress node of the packet flow performance measurement path. In the embodiment of the present application, a "node" may refer to a device that forwards service traffic in a network, for example, a "node" may be a router, a switch, an Optical Transport Network (English: Optical Transport Network, OTN for short) device, a packet transmission network (English: Packet Transport Network, abbreviated: PTN) equipment or wavelength division multiplexing (English: Wavelength Division Multiplexing, abbreviated: WDM) equipment. For example, the ingress node and the egress node may be routers that forward packets.
图2为本申请实施例提供了一种报文流性能测量的方法。图2所示的方法包括S201、S202和S203。举例来说，所述方法可以应用于图1所示的应用场景中。FIG. 2 provides a method for measuring packet flow performance according to the embodiment of the present application. The method shown in FIG. 2 includes S201, S202 and S203. For example, the method can be applied to the application scenario shown in FIG. 1 .
S201从所述报文中选择染色位。S201 Select a colored bit from the packet.
举例来说，SDN控制器可以根据IP五元组信息确定要检测的目标报文，然后SDN控制器在目标报文可供选择的比特位中选择染色位。以IP FPM流性能测量为例，SDN控制器可以选择目标报文ToS字段第3比特位至第7比特位和标记字段的第0比特位的任意比特位作为染色位。For example, the SDN controller may determine the target packet to be detected according to the IP quintuple information, and then the SDN controller selects the coloring bits from the optional bits of the target packet. Taking IP FPM flow performance measurement as an example, the SDN controller can select any bit from the 3rd bit to the 7th bit of the ToS field of the target packet and the 0th bit of the flag field as the coloring bit.
S202通过检测判断所述染色位是否与所述报文的其它业务存在冲突。S202 Determine whether the colored bit conflicts with other services of the packet by detecting.
在选择确定染色位之后，需要对所选择的染色位进行检测，以判断该染色位是否与所述报文的其它业务存在冲突。举例来说，在入口节点将目标报文转发到出口节点的过程中，SDN控制器可以通过检测判断染色位是否与报文的其它业务发生冲突，也可以由测量控制设备通过检测判断染色位是否与报文的其它业务存在冲突。如果确定该染色位与所述报文的其它业务存在冲突，则SDN控制器或者测量控制设备继续选择其它染色位进行判断，直到发现与该报文的其它业务不存在冲突的染色位。After the coloring bit is selected and determined, the selected coloring bit needs to be detected to determine whether the coloring bit conflicts with other services of the message. For example, when the ingress node forwards the target message to the egress node, the SDN controller can determine whether the dyed bit conflicts with other services of the message through detection, or the measurement control device can determine whether the dyed bit is Conflicts with other services of the message. If it is determined that the colored bit conflicts with other services of the message, the SDN controller or the measurement control device continues to select other colored bits for judgment until a colored bit that does not conflict with other services of the message is found.
S203当所述染色位与所述报文的其它业务不存在冲突时，利用所述染色位进行报文流性能检测。S203 When there is no conflict between the colored bits and other services of the packet, use the colored bits to detect packet flow performance.
举例来说，在确定所选染色位与该报文的其它业务不存在冲突的情况下，可以通过标识该染色位对报文流性能进行检测。以IP FPM流性能测量为例，在确定染色位与该报文的其它业务不存在冲突时，可对报文染色位进行周期性的标识，例如将染色位置位为1或者将染色位复位为0，以测量报文的丢包统计和时延统计。For example, in a case where it is determined that the selected colored bit does not conflict with other services of the packet, the packet flow performance may be detected by identifying the colored bit. Taking IP FPM flow performance measurement as an example, when it is determined that there is no conflict between the dyed bit and other services of the packet, the dyed bit of the packet can be periodically marked, for example, the dyed bit is set to 1 or the dyed bit is reset to 0, to measure packet loss statistics and delay statistics of packets.
如果所述染色位与所述报文的其它业务存在冲突，则继续选择其它染色位进行检测以判断第二次选择的染色位是否与该报文的其它业务存在冲突，如此循环，直到检测到与该报文其它业务不存在冲突的染色位。如果通过检测发现可选择的染色位都与该报文的其它业务存在冲突，则控制设备通知用户不能进行报文流性能检测。If the dyed bit conflicts with other services of the message, continue to select other dyed bits for detection to determine whether the second selected dyed bit conflicts with other services of the message, and so on until detected Colored bits that do not conflict with other services in the message. If it is found through detection that the optional coloring bits conflict with other services of the packet, the control device notifies the user that packet flow performance detection cannot be performed.
如图3A所示以IP FPM流性能测量为例，具体介绍报文流行性检测的方法流程示意图，图3A所示的方法包括S301、S302、S303、S304和S305，可选的，该方法还可以在S303和S304之间增加步骤S306。举例来说，所述方法可以应用于图1所述的应用场景中。图1中入口节点101可以是图3A中所示的方法中涉及的入口节点，图1中出口节点103可以是图3A所示的方法中涉及的出口节点。图1中的控制设备可以是图3A所示方法中涉及的控制设备。As shown in Figure 3A, taking IP FPM flow performance measurement as an example, a schematic diagram of the method flow chart for packet popularity detection is specifically introduced. The method shown in Figure 3A includes S301, S302, S303, S304 and S305. Optionally, the method also includes Step S306 may be added between S303 and S304. For example, the method can be applied to the application scenario described in FIG. 1 . The entry node 101 in FIG. 1 may be the entry node involved in the method shown in FIG. 3A , and the exit node 103 in FIG. 1 may be the exit node involved in the method shown in FIG. 3A . The control device in FIG. 1 may be the control device involved in the method shown in FIG. 3A.
S301，从所述报文中选择染色位。S301. Select a colored bit from the packet.
举例来说，首先SDN控制器可以根据会话发起协议、源IP地址、目的IP地址、源端口和目的端口五元组进行流识别，确定目标报文。SDN控制器还可以根据上述信息的二元组、三元组、五元组等组合确定目标报文，组合越长可监测的数据流就越细。SDN控制器根据目标报文确定目标报文转发路径以及目标报文性能测量的入口节点和出口节点。SDN控制器可以选择目标报文的服务类型字段的第3比特位至第7比特位和标记字段的第0比特位中比特位进行标识。如果需要对目标报文同时进行时延统计和丢包统计，SDN控制器可以同时选择该目标报文的两个染色位。For example, first, the SDN controller can perform flow identification according to the session initiation protocol, source IP address, destination IP address, source port, and destination port quintuple to determine the target packet. The SDN controller can also determine the target message according to the combination of the two-tuple, three-tuple, and five-tuple of the above information. The longer the combination, the finer the data flow that can be monitored. The SDN controller determines the forwarding path of the target message and the ingress node and the egress node for performance measurement of the target message according to the target message. The SDN controller may select the bits from the 3rd bit to the 7th bit of the service type field of the target message and the 0th bit of the flag field for identification. If it is necessary to perform delay statistics and packet loss statistics on the target packet at the same time, the SDN controller can simultaneously select the two coloring bits of the target packet.
S302，检测所述报文的所述染色位是否与所述报文的其它业务存在冲突。如图3B所示为实施例提供一种检测染色位是否与报文的其它业务发生冲的方法流程示意图。所述方法包括S311、S312和S313。S302. Detect whether the colored bits of the packet conflict with other services of the packet. As shown in FIG. 3B , the embodiment provides a schematic flowchart of a method for detecting whether the dyed bits collide with other services of the message. The method includes S311, S312 and S313.
S311，控制设备将报文的染色位的配置信息发送给入口节点和出口节点，所述的染色位的配置信息包括所述染色位的位置信息。S311. The control device sends the configuration information of the dyed bits of the packet to the ingress node and the egress node, where the configuration information of the dyed bits includes position information of the dyed bits.
举例来说，所述待检测染色位的检测配置信息包括待检测染色位的位置信息，如前所述，所述待检测染色位为便于对报文做报文流量性能检测，例如丢包、延时或其他类似统计而对报文进行特征标记的比特位。所述染色位的位置信息为所述待检测的染色位在所述报文中的位置，例如，以待检测染色位为一个染色位为例进行说明(为了描述方便可以称为第一染色位)，该第一染色位的位置信息为上例中报文的服务类型字段的第3比特位或标记字段的第0比特位。在待检测的染色位为多个的情况下，依次可以称为第一染色位，第二染色位，至第N染色位(N为大于1的正整数)。例如，以待检测的染色位为三个染色位为例进行说明(为了描述方便可以称为第一染色位、第二染色位以及第三染色位)则染色位检测配置信息包括各染色位分别在所述报文中的位置，如分别为上例中报文的服务类型字段的第3比特位至第5比特位。For example, the detection configuration information of the coloring bit to be detected includes the position information of the coloring bit to be detected. As mentioned above, the coloring bit to be detected is for the convenience of packet flow performance detection on the message, such as packet loss, Delay or other similar statistics to characterize the bit of the packet. The position information of the dyed bit is the position of the dyed bit to be detected in the message, for example, the dyed bit to be detected is an example for illustration (for convenience of description, it can be called the first dyed bit ), the position information of the first colored bit is the 3rd bit of the service type field of the message in the above example or the 0th bit of the flag field. In the case of multiple dyeing sites to be detected, they can be called the first dyeing site, the second dyeing site, and the Nth dyeing site (N is a positive integer greater than 1) in sequence. For example, take three dyeing positions to be detected as an example (for the convenience of description, they may be referred to as the first dyeing position, the second dyeing position, and the third dyeing position), then the dyeing position detection configuration information includes each dyeing position respectively The positions in the message are, for example, the 3rd bit to the 5th bit of the service type field of the message in the above example.
举例来说，控制设备可以通过网络配置协议向入口节点和出口节点下发待检测染色位的配置信息，以及目标报文的信息。控制设备还可以通过管理信息库向入口节点和出口节点下发上述待检测染色位的配置信息。For example, the control device can send the configuration information of the color bit to be detected and the information of the target message to the ingress node and the egress node through the network configuration protocol. The control device may also deliver the configuration information of the dyed bit to be detected to the entry node and the exit node through the management information base.
举例来说，IP FPM流性能检测的染色位可以包括该报文服务类型字段的第3比特位至第7比特位和标记字段的第0比特位，共6个比特位。控制设备可以选择上述6个比特位中的一个或者多个进行检测。例如，以待检测的染色位为两个染色位为例，目标报文的待检测染色位可以是服务类型字段的第4比特位和第5比特位。For example, the colored bits of the IP FPM flow performance detection may include the 3rd bit to the 7th bit of the service type field of the message and the 0th bit of the flag field, a total of 6 bits. The control device may select one or more of the above six bits for detection. For example, if the coloring bits to be detected are two coloring bits as an example, the coloring bits to be detected in the target message may be the fourth bit and the fifth bit of the service type field.
所述入口节点和所述出口节点根据接收到的染色位配置信息对多个目标报文进行检测，并将检测数据进行统计。The ingress node and the egress node detect a plurality of target messages according to the received color bit configuration information, and make statistics on the detected data.
S312，所述控制设备接收所述接收所述入口节点根据所述所述染色位的位置信息获得的第一检测数据和所述出口节点根据所述染色位的位置信息获得的第二检测数据。S312. The control device receives the first detection data obtained by the ingress node according to the position information of the dyed bit and the second detection data obtained by the egress node according to the position information of the dyed bit.
具体实施例中，所述第一检测数据为所述入口节点记录的在设定周期内接收到的报文中的所述待检测染色位的数值的检测结果或者所述入口节点记录的接收到的设定数量的报文中的所述待检测染色位的数值的检测结果，所述第二检测数据为所述出口节点记录的在所述设定周期内接收到的报文中所述待检测染色位的数值的检测结果或者所述出口节点记录的接收到的设定数量的报文中的所述待检测染色位的数值的检测结果。In a specific embodiment, the first detection data is the detection result of the numerical value of the coloring bit to be detected in the message received by the entry node within the set period or the reception record of the entry node The detection result of the numerical value of the color bit to be detected in the set number of messages, and the second detection data is the value of the color bit to be detected in the message received by the egress node within the set period. Detecting the detection result of the numerical value of the dyed bit or the detection result of the numerical value of the dyed bit to be detected in the received set number of messages recorded by the egress node.
控制设备接收入口节点发送的检测数据，这些检测数据是入口节点对目标报文统计的上述第一染色位的数值，这些数值包括0、1以及既不是0也不是1的空值。当所述第一染色位为空值时表明该染色位为不可用比特位，不能对该比特位进行染色标识。控制设备接收出口节点发送的数据统计信息，这些数据统计信息是出口节点对目标报文统计的第一染色位的数值，这些数值同样包括0、1以及空值。举例来说，控制设备接收入口节点发送的第一数组的数值都是1，控制设备接收出口节点发送的第二数组的数值也都是1。The control device receives the detection data sent by the ingress node, and the detection data is the value of the above-mentioned first colored bit that the ingress node counts on the target packet, and these values include 0, 1 and null values that are neither 0 nor 1. When the first coloring bit is null, it indicates that the coloring bit is an unusable bit, and the bit cannot be marked with coloring. The control device receives the data statistics information sent by the egress node, and the data statistics information is the value of the first colored bit that the egress node counts on the target packet, and these values also include 0, 1 and null values. For example, the control device receives all 1s in the first array sent by the entry node, and the control device receives all 1s in the second array sent by the exit node.

在所述入口节点或出口节点接收到的所述多个报文中的第一染色位的数值所组成的数值集的情况下：In the case of the value set formed by the values of the first colored bits in the plurality of messages received by the ingress node or the egress node:
当所述入口节点接收到的所述第一染色位的第一数值集中的各个数值与所述出口节点接收到的第一染色位的第二数值集的各个数值同时为1时，或者所述第一数值集中各个数值与所述第二数值集的各个数值同时为0时，则确定不存在冲突。When each value in the first value set of the first colored bit received by the ingress node and each value in the second value set of the first colored bit received by the egress node are 1 at the same time, or the When each value in the first value set and each value in the second value set are 0 at the same time, it is determined that there is no conflict.

It can be understood that, in the above Table 1, if the first value set of the first color bit reported by the entry node is [000...0] (the values in the omitted places are all 0), the first color bit reported by the exit node The second value set of the bits is [000...0] (wherein the value of the omission is all 0), then it can also be determined that there is no conflict between using the dyed bits to detect the packet traffic performance and other services of the packet.
当所述入口节点接收到的所述第一染色位的第一数值集中的各个数值与所述出口节点接收到的所述第一染色位的第二数值集中的各个数值至少存在一个数值不相同时，则确定存在冲突。When each value in the first value set of the first colored bit received by the ingress node is different from each value in the second value set of the first colored bit received by the egress node, at least one value is different At the same time, it is determined that there is a conflict.
如下表4所示，入口节点上报的所述第一染色位的第一数值集为[111…1]，出口节点上报的所述第一染色位的第一数值集为[111…0](假设以上省略处的数值相同，都为1或都为0)，则可以确定利用所述染色位进行报文流量性能检测与该报文的其他业务存在冲突。或者，如上述表2中，如果入口节点上报的所述第一染色位的第一数值集为[110…1]，则可以不用等到接收出口节点的第二数值集即可直接确定利用所述染色位进行报文流量性能检测与该报文的其他业务存在冲突，或者如果出口节点上报的所述第一染色位的第二数值集为[110…1](假设以上省略处的数值相同，都为1或都为0)，则也可以不用等到接收入口节点的第一数值集即可直接确定利用所述染色位进行报文流量性能检测与该报文的其他业务存在冲突。As shown in Table 4 below, the first value set of the first dyed bit reported by the entry node is [111...1], and the first value set of the first dyed bit reported by the exit node is [111...0] ( Assuming that the above omitted values are the same (both are 1 or all are 0), it can be determined that there is a conflict between using the dyed bits to detect packet traffic performance and other services of the packet.

在另一具体实施方式中，当所述入口节点接收到的所述第一染色位的第一数值集中的各个数值与所述出口节点接收到的所述第一染色位的第二数值集中的各个数值都为空(即及不为0也不为1)的情况下，确认为异常，可能为无业务流量或者IP FPM的流量特征与实际业务流量不匹配等，并提示用户检查配置或者检查网络情况。可以理解在这种情况下，在这种情况下，也可以默认为利用所述染色位进行报文流量性能检测与该报文的其他业务存在冲突，而选择其他染色位继续进行上述判断。In another specific implementation manner, when each value in the first value set of the first colored bits received by the ingress node is the same as that in the second value set of the first colored bits received by the egress node If each value is empty (that is, neither 0 nor 1), it is confirmed as an abnormality. It may be that there is no business traffic or the traffic characteristics of IP FPM do not match the actual business traffic, etc., and the user is prompted to check the configuration or check Network situation. It can be understood that in this case, in this case, it can also be defaulted that using the dyed bit to perform packet traffic performance detection conflicts with other services of the packet, and select other dyed bits to continue the above judgment.
在所述入口节点或出口节点接收到的多个报文中的第一染色位数值统计值的场合下：In the case of the statistical value of the first colored bit value in the plurality of messages received by the ingress node or the egress node:
当所述入口节点接收到的所述第一染色位的第一统计值与所述出口节点接收到的第一染色位的第二统计值相同，且所述第一统计值和第二统计值中数值为0的统计值都为0或者所述第一统计值和第二统计值中数值为1的统计值都为0时，则确定不存在冲突。When the first statistical value of the first colored bit received by the ingress node is the same as the second statistical value of the first colored bit received by the egress node, and the first statistical value and the second statistical value When the statistic values with a value of 0 are all 0 or the statistic values with a value of 1 among the first statistic value and the second statistic value are both 0, it is determined that there is no conflict.
如下表5所示，所述入口节点接收到的多个报文中(此处以10个为例)的第一染色位的第一统计值中，数值为0的计数为10个，数值为1的计数为0个，出口节点接收到的多个报文中的第一染色位的第二统计值中，数值为0的计数为10个，数值为1的计数为0个，则可以确定利用所述染色位进行报文流量性能检测与该报文的其他业务不存在冲突。可以理解，下表5中，如果所述第一统计值中，数值为0的计数为0个，数值为1的计数为10个，以及第二统计值中，数值为0的计数为0个，数值为1的计数为10个，则也可以确定利用所述染色位进行报文流量性能检测与该报文的其他业务不存在冲突。As shown in Table 5 below, among the first statistical values of the first dyed bits in the plurality of messages received by the ingress node (here, 10 are taken as an example), the counts with a value of 0 are 10, and the value is 1 The count is 0, and among the second statistical values of the first colored bits in multiple messages received by the egress node, the count of the value 0 is 10, and the count of the value 1 is 0, then it can be determined that the use There is no conflict between the packet flow performance detection performed by the dyed bits and other services of the packet. It can be understood that in Table 5 below, if in the first statistical value, counts with a value of 0 are 0, counts with a value of 1 are 10, and in the second statistical value, counts with a value of 0 are 0 , and the number of counts with a value of 1 is 10, then it can also be determined that there is no conflict between using the dyed bit to perform packet traffic performance detection and other services of the packet.
表5多个报文中第一染色位数值统计值Table 5 Statistical value of the first coloring bit value in multiple messages
入口节点将报文转发到出口节点的过程中可能出现丢包的情况，因此会导致入口节点和出口节点统计到的报文总数不相同，如下表6所示，所述入口节点接收到的多个报文中(此处以10个为例)的第一染色位的第一统计值中，数值为0的计数为10个，数值为1的计数为0个。由于可能出现丢包的情况，所述出口节点接收到的多个报文中的第一染色位的第二统计值中，数值为0的计数为8个，数值为1的计数为0个。由于第一统计值与第二统计值都为0，因此可以确定所述染色位与该报文的其它业务不存在冲突，可以利用第一染色位进行报文流性能测量。同样可以理解，下表6中，如果所述第一统计值中，数值为0的计数为0个，数值为1的计数为10个，以及第二统计值中，数值0的计数为0，数值为1的计数为8个，则也可以确定利用所述染色位进行报文流性能检测与该报文的其它业务不存在冲突。Packet loss may occur when the ingress node forwards packets to the egress node, so the total number of packets counted by the ingress node and the egress node will be different, as shown in Table 6 below, the number of packets received by the ingress node Among the first statistical values of the first dyed bits in a message (here, 10 are taken as an example), counts with a value of 0 are 10, and counts with a value of 1 are 0. Due to possible packet loss, among the second statistical values of the first colored bits in the plurality of messages received by the egress node, there are 8 counts with a value of 0, and 0 counts with a value of 1. Since both the first statistical value and the second statistical value are 0, it can be determined that there is no conflict between the colored bit and other services of the packet, and the first colored bit can be used to measure packet flow performance. It can also be understood that in the following table 6, if in the first statistical value, the count of the value 0 is 0, the count of the value 1 is 10, and in the second statistical value, the count of the value 0 is 0, If the number of counts with a value of 1 is 8, it can also be determined that there is no conflict between using the dyed bit to perform packet flow performance detection and other services of the packet.
表6多个报文中第一染色位数值统计值Table 6 Statistical value of the first coloring bit value in multiple messages
当所述入口节点接收到的所述第一染色位的第一统计值与所述出口节点接收到的第一染色位的第二统计值不相同时，则确定存在冲突。When the first statistical value of the first colored bit received by the ingress node is different from the second statistical value of the first colored bit received by the egress node, it is determined that there is a conflict.
如下表7所示，当所述入口节点接收到的多个报文中(此处以10个为例))的第一染色位的第一统计值中，数值为0的计数为8个，数值为2的计数为0个时，则可以不用等到接收出口节点的第二统计值即可直接确定利用所述染色位进行报文流量性能检测与该报文的其他业务存在冲突；或者当出口节点接收到的多个报文中的第一染色位的第二统计值中，数值为0的计数为8个，数值为1的计数为2个时，也可以不同等到接收入口节点的第一统计值即可直接确定利用所述染色位进行报文流量性能检测与该报文的其他业务存在冲突。As shown in Table 7 below, when the number of messages received by the entry node (take 10 as an example here) in the first statistical value of the first dyed bit, the number of counts with a value of 0 is 8, and the value When the count of 2 is 0, it can be directly determined that there is a conflict between using the dyed bit to perform message traffic performance detection and other services of the message without waiting to receive the second statistical value of the egress node; or when the egress node Among the second statistical values of the first colored bits in the received multiple messages, when the count of the value 0 is 8, and the count of the value 1 is 2, it may not wait until the first statistical value of the entry node is received. It can be directly determined that there is a conflict between using the dyed bit to perform packet traffic performance detection and other services of the packet.
表8多个报文中第一染色位数值统计值Table 8 Statistical value of the first coloring bit value in multiple messages
在另一具体实施方式中，当所述入口节点接收到的所述第一染色位的第一统计值中，数值为0的统计值和针对数值为1的统计值都不为0，或者当所述出口节点接收到的所述第一染色位的第二统计值中，数值为0的统计值和针对数值为1的统计值都不为0时，则确认为异常，例如可能为无业务流量或者IP FPM的流量特征与实际业务流量不匹配等，并提示用户检查配置或者检查网络情况。可以理解在这种情况下，在这种情况下也可以默认为利用所述染色位进行报文流量性能检测与该报文的其他业务存在冲突，而选择其他染色位继续进行上述判断。In another specific implementation manner, when the first statistical value of the first colored bit received by the ingress node, neither the statistical value with a value of 0 nor the statistical value with a value of 1 is 0, or when In the second statistical value of the first colored bit received by the egress node, if the statistical value for the value of 0 and the statistical value for the value of 1 are not 0, it is confirmed as abnormal, for example, it may be no service The traffic or the traffic characteristics of IP FPM do not match the actual service traffic, etc., and the user is prompted to check the configuration or check the network status. It can be understood that in this case, it can also be defaulted that using the dyed bit to perform packet traffic performance detection conflicts with other services of the packet, and select other dyed bits to continue the above judgment.
在入口节点和出口节点接收染色位配置信息之后至入口节点和出口节点根据染色位配置信息判断染色位是否与其它业务存在冲突之前，所述方法还包括：After the ingress node and the egress node receive the dyed bit configuration information and before the ingress node and the egress node judge whether the dyed bit conflicts with other services according to the dyed bit configuration information, the method further includes:
控制设备通知入口节点周期性的将所述染色位置位为1或者周期性的将所述染色位复位为0。The control device notifies the ingress node to periodically set the colored bit to 1 or periodically reset the colored bit to 0.
举例来说，入口节点根据控制设备的通知，在一个周期内将待检测染色位置位为1。入口节点在下一个周期内将待检测染色位复位为0，对染色位进行特征标识。For example, the entry node sets the dyeing position to be detected as 1 in one cycle according to the notification of the control device. In the next cycle, the entry node resets the dyed bits to be detected to 0, and performs characteristic identification on the dyed bits.
入口节点接收到染色位的位置信息后，在设定周期内对染色位进行特征标识，这种特征标识方法与IP FPM流性能测量中的特征标识方法相同。然后入口节点和出口节点采用S302中的方法，收集和统计染色位的数据信息并将所述所述数据信息上报给控制设备，由控制设备根据上述相同的计算方法来判断染色位是否与该报文的其它业务存在冲突。After the ingress node receives the location information of the dyed bits, it performs feature identification on the dyed bits within a set period. This feature identification method is the same as the feature identification method in IP FPM flow performance measurement. Then the entry node and the exit node adopt the method in S302 to collect and count the data information of the dyed bits and report the data information to the control device, and the control device judges whether the dyed bits are consistent with the reported data according to the same calculation method as above. Wen's other business conflicts.
入口节点对待检测染色位进行周期性特征标识的方法与IP FPM流性能检测的方法相同，因此这种检测方法更加接近IP FPM流性能检测的要求。另一方面，如下表9所示，入口节点接收到待检测染色位的位置信息后，对接收到的多个报文中(此处以10个为例)的第一染色位的第一统计值中，数值为0的计数为8，数值为1的计数为2。入口节点根据控制设备的要求在设定周期内将待检测染色位复位为0，因此入口节点在对染色位进行特征标识之后再次统计待检测染色位的第一统计值，数值为0的计数为10个，数值为1的计数为0个。所述出口节点接收到的多个报文中第一染色位的第二统计值中，数值为0的计数为10个，数值为1的计数为0个。由于入口节点在进行特征标识之后的第一统计值与出口节点的第二统计值中值为1均有大于0的整数计数，值为0均无计数，因此可以确定所述染色位与该报文的其它业务不存在冲突。如上表7中所示，在入口节点不对待检测染色位进行周期性特征标识，如果出现表7中所统计的数值，则会直接确定IP FPM流性能检测的染色位与其它业务存在冲突。如果入口节点和出口节点进行特征标识后，入口节点和出口节点同样是值为0均有大于0的整数计数，值为1技术均为0，则同样可以确认所述染色位与该报文的其它业务不存在冲突。因此，上述方法使得染色位冲突判断结果更加准确。The method of periodical feature identification of the color bit to be detected by the ingress node is the same as the method of IP FPM flow performance detection, so this detection method is closer to the requirements of IP FPM flow performance detection. On the other hand, as shown in Table 9 below, after the ingress node receives the position information of the dyed bits to be detected, the first statistical value of the first dyed bits in the received multiple messages (here 10 are taken as an example) In , the count of 0 is 8, and the count of 1 is 2. The entry node resets the coloring bit to be detected to 0 within the set period according to the requirements of the control device, so the entry node counts the first statistical value of the coloring bit to be detected after the characteristic identification of the coloring bit, and the count of the value of 0 is 10, the count of 1 is 0. Among the second statistical values of the first colored bits in the plurality of messages received by the egress node, counts with a value of 0 are 10, and counts with a value of 1 are 0. Since the first statistical value of the entry node after the feature identification and the second statistical value of the exit node have an integer count greater than 0 for a value of 1, and have no count for a value of 0, it can be determined that the coloring bit and the report There is no conflict with Wen's other business. As shown in Table 7 above, the ingress node does not perform periodic feature identification on the dyed bit to be detected. If the statistical value in Table 7 appears, it will be directly determined that the dyed bit of IP FPM flow performance detection conflicts with other services. If after the ingress node and the egress node carry out the feature identification, the ingress node and the egress node also have an integer count greater than 0 with a value of 0, and a value of 1 means that both are 0, then it can also be confirmed that the dyed bit is consistent with the message's There is no conflict with other businesses. Therefore, the above method makes the result of judging the color bit conflict more accurate.

举例来说，通过检测确定染色位与该报文的其它业务不存在冲突的情况下，SDN控制器将该染色位的位置通过下发到入口节点和出口节点。入口节点和出口节点根据SDN控制器下发的信息确定染色位的位置后，入口节点周期性的对染色位进行特征标识，比如在一个周期将染色位置位为1，在下一个周期复位为0，从而可将业务报文按照染色位的标识划分为不同的测量区，比如将染色位标识为1的划分为第一测量区，将标识为0的划分为第二测量区。For example, when it is determined through detection that there is no conflict between the dyed bit and other services of the packet, the SDN controller sends the position of the dyed bit to the ingress node and the egress node. After the ingress node and the egress node determine the position of the dyed bit according to the information sent by the SDN controller, the ingress node periodically identifies the characteristic of the dyed bit, such as setting the dyed position to 1 in one cycle and resetting it to 0 in the next cycle. Therefore, the service packets can be divided into different measurement areas according to the identification of the color bit, for example, the color bit identification of 1 is divided into the first measurement area, and the identification of the color bit is 0 is divided into the second measurement area.
S304从所述入口节点接收第一统计数据，并从所述出口节点接收第二统计数据，所述第一统计数据为所述入口节点在设定周期内对染色为进行标识的统计数据，所述第二统计数据为所述出口节点在所述周期内对染色位的统计数据。S304 Receive first statistic data from the entry node, and receive second statistic data from the exit node, the first statistic data is the statistic data for the entry node to identify dyeing within a set period, so The second statistical data is the statistical data of the dyed bits by the egress node in the period.
举例来说，入口节点和出口节点根据染色位的特征标识将业务报文划分为不同测量区。入口节点和出口节点对不同测量去分别进行测量统计，并将测量统计的数据上报给控制设备。For example, the ingress node and the egress node divide the service packets into different measurement areas according to the characteristic identification of the colored bits. The ingress node and the egress node respectively perform measurement statistics for different measurements, and report the measurement statistics data to the control device.
S305根据所述第一统计数据和所述第二统计数据获得报文流性能检测数据。S305 Obtain packet flow performance detection data according to the first statistical data and the second statistical data.
举例来说，控制设备接收到入口节点和出口节点发送的第一统计数据和第二统计数据后，根据所述数据获得报文流性能测量结果。以测量报文丢包统计为例，如下表10所示，如果入口节点统计标识为1的报文个数为10，出口节点统计获得的标识为1的报文个数为9个，则可以计算出业务报文的丢包数为1。For example, after receiving the first statistical data and the second statistical data sent by the ingress node and the egress node, the control device obtains a packet flow performance measurement result according to the data. Taking packet loss statistics of measurement packets as an example, as shown in Table 10 below, if the ingress node counts 10 packets with the flag 1, and the egress node counts 9 packets with the flag 1, then you can The calculated packet loss number of service packets is 1.
