本发明涉及通信技术领域，特别涉及一种实现分组传送网性能劣化定位方法和系统。The invention relates to the field of communication technology, in particular to a method and system for realizing performance degradation positioning of a packet transport network.
背景技术Background technique
随着运营商市场竞争的加剧，用户体验成为运营商关注的重点。对于基础承载网络层面而言，需要持续完善基于客户感知的端到端业务质量保障机制。目前分组传输网(PTN)承载集客专线或者移动基站回传业务过程中，缺乏有效的端到端性能劣化定位手段。With the intensification of competition in the operator market, user experience has become the focus of operators' attention. For the basic bearer network layer, it is necessary to continuously improve the end-to-end service quality assurance mechanism based on customer perception. Currently, there is a lack of effective means for locating end-to-end performance degradation when the packet transmission network (PTN) carries private lines for customers or backhaul services of mobile base stations.
目前PTN网络采用分层服务提供商(LSP)隧道或者伪线(PW)的OAM机制，或者采用插入外部仪表探针的方式，可以监测到端到端业务的性能劣化。但是当检测到性能劣化以后，维护人员定位出现丢包率或者时延性能劣化的位置非常困难。At present, the PTN network adopts the OAM mechanism of Layered Service Provider (LSP) tunnel or Pseudowire (PW), or inserts an external instrument probe to monitor the performance degradation of end-to-end services. However, after performance degradation is detected, it is very difficult for maintenance personnel to locate the location where packet loss rate or delay performance degradation occurs.
参见图1，图1为PTN承载集客专线组网示意图。城域PTN网络一般分为城域核心、汇聚和接入三个层次，网络结构相对复杂。Referring to Fig. 1, Fig. 1 is a schematic diagram of a PTN-carried inbound dedicated line network. The metropolitan area PTN network is generally divided into three levels: metropolitan area core, convergence and access, and the network structure is relatively complex.
现有的OAM机制均为端到端的性能检测机制。对于接入层出现的性能劣化，还可以通过接入环上落地业务进行综合判定，如到达公司分支设备1的LSP上没有检测到性能劣化，而经过公司分支设备1对应的PTN设备到达公司分支设备2上的LSP出现了性能劣化，可以初步定位性能劣化点在公司分支设备1到公司分支设备2之间的PTN链路上。但是对于汇聚层和核心层，业务相对复杂，难于定位性能劣化点。Existing OAM mechanisms are all end-to-end performance detection mechanisms. For performance degradation at the access layer, a comprehensive judgment can also be made through the landing services on the access ring. For example, no performance degradation is detected on the LSP that reaches company branch device 1, but the company branch arrives at the company branch through the PTN device corresponding to company branch device 1. The performance of the LSP on device 2 is degraded. The point of performance degradation can be preliminarily located on the PTN link between company branch device 1 and company branch device 2. But for the aggregation layer and the core layer, the business is relatively complex, and it is difficult to locate the point of performance degradation.

为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图并举实施例，对本发明的技术方案进行详细说明。In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.
本申请实施例中提供一种实现分组传送网性能劣化定位方法，应用于包括源PTN设备、中间PTN设备和目的PTN设备的PTN中，源PTN设备为源维护终结点(MEP)所在的PTN设备，中间PTN设备为维护中间点(MIP)所在的PTN设备，目的PTN设备为目的MEP所在的PTN设备。In the embodiment of the present application, a method for locating packet transport network performance degradation is provided, which is applied to a PTN including a source PTN device, an intermediate PTN device, and a destination PTN device, where the source PTN device is the PTN device where the source maintenance termination point (MEP) is located , the intermediate PTN device is the PTN device where the maintenance intermediate point (MIP) is located, and the destination PTN device is the PTN device where the destination MEP is located.
参见图2，图2为本申请实施例中PTN示意图。图2中与公司分支设备相连的PTN设备为源PTN设备，即PTN设备1，该PTN设备上的MEP为源MEP，与公司总部设备相连的PTN设备为目的PTN设备，即PTN设备5，该PTN设备上的MEP为目的MEP，其他PTN设备为中间PTN设备，该PTN设备上的节点为MIP。Referring to FIG. 2, FIG. 2 is a schematic diagram of the PTN in the embodiment of the present application. In Figure 2, the PTN device connected to the branch device of the company is the source PTN device, that is, PTN device 1, the MEP on the PTN device is the source MEP, and the PTN device connected to the company headquarters device is the destination PTN device, that is, PTN device 5. The MEP on the PTN device is the destination MEP, other PTN devices are intermediate PTN devices, and the nodes on the PTN device are MIPs.
下面结合附图，详细说明本申请实施例中实现PTN性能劣化定位过程。这里的PTN性能劣化，即PTN中各PTN设备之间的链路的性能劣化，链路的性能劣化指链路是否拥塞等。The process of locating PTN performance degradation in the embodiment of the present application will be described in detail below with reference to the accompanying drawings. Here, the performance degradation of the PTN refers to the performance degradation of the link between the PTN devices in the PTN, and the performance degradation of the link refers to whether the link is congested or not.
参见图3，图3本申请实施例中PTN性能劣化定位流程示意图。具体步骤为：Referring to FIG. 3 , FIG. 3 is a schematic diagram of a PTN performance degradation locating process in the embodiment of the present application. The specific steps are:
步骤301，源PTN设备使用快速报文发送周期发送LB请求报文。In step 301, the source PTN device sends the LB request message using the fast message sending period.
现有实现中，环回(Loop Back，LB)请求报文的发送周期为慢周期发送，即1个/秒，本申请该实施例中扩展为快速报文发送周期，如3.33ms，或10ms发送一个，即300个/s、100个/s。In the existing implementation, the sending period of the loopback (Loop Back, LB) request message is sent in a slow period, that is, 1 message per second. In this embodiment of the present application, it is extended to a fast message sending period, such as 3.33ms, or 10ms Send one, that is, 300/s, 100/s.
在具体实现时，在周期改变的情况下，可以根据实际需要增加LB请求报文的发送速率，如10Mbps。In specific implementation, when the period changes, the sending rate of the LB request message can be increased according to actual needs, such as 10 Mbps.
步骤302，中间PTN设备接收到LB请求报文时，向目的PTN设备方向发送LB请求报文，并向源PTN设备发送LB响应报文。Step 302, when the intermediate PTN device receives the LB request message, it sends the LB request message to the destination PTN device, and sends the LB response message to the source PTN device.
步骤303，目的PTN设备接收到LB请求报文时，向源PTN设备发送LB响应报文。Step 303, when the destination PTN device receives the LB request message, it sends the LB response message to the source PTN device.
该实施例中，中间的PTN设备，以及目的PTN设备增加发送响应LB响应报文的功能，即在接收到LB请求报文时，向源PTN设备返回LB响应报文。In this embodiment, the intermediate PTN device and the destination PTN device add the function of sending a response LB response message, that is, when receiving the LB request message, return the LB response message to the source PTN device.
中间PTN设备在接收到LB请求报文时，向目的PTN设备发送LB请求报文的实现同现有实现。When the intermediate PTN device receives the LB request message, the implementation of sending the LB request message to the destination PTN device is the same as the existing implementation.
步骤304，源PTN设备接收中间PTN设备和目的PTN设备发送的LB响应报文，并分别记录每个周期内接收到的中间PTN设备，以及目的PTN设备发送的LB响应报文的条数。Step 304, the source PTN device receives the LB response messages sent by the intermediate PTN device and the destination PTN device, and records the number of LB response messages received by the intermediate PTN device and the destination PTN device in each cycle.
源PTN设备在接收到其他PTN设备返回的LB响应报文时，记录每周期接收到LB响应条数。具体实现时，可以使用每接收一条报文，将接收到的报文的条数增加1。When the source PTN device receives LB response packets returned by other PTN devices, it records the number of LB responses received per cycle. During specific implementation, the number of received messages may be increased by 1 each time a message is received.
如发送LB请求报文的周期T，从时刻t1开始，则当前周期为t1到t1+T；则接收LB响应报文的对应的周期为t1+d到t1+T+d，使用时间延时一定时间d作为接收LB响应报文的对应周期，这里只是一种举例，不限制具体实现周期记录的接收LB响应报文的条数的方式。For example, the cycle T of sending LB request messages starts from time t1, and the current cycle is t1 to t1+T; the corresponding cycle of receiving LB response messages is t1+d to t1+T+d, using time delay A certain period of time d is used as the corresponding period for receiving LB response messages, which is just an example here, and does not limit the specific implementation of the method of periodically recording the number of received LB response messages.
每个PTN设备有唯一的标识(ID)，在发送LB响应报文时，携带该唯一标识，使源PTN设备能够识别出哪个PTN设备发送的LB响应报文。Each PTN device has a unique identifier (ID), which is carried when sending the LB response message, so that the source PTN device can identify which PTN device sends the LB response message.
该实施例中发送LB请求报文和LB响应报文的优先级设置为与LSP业务报文的优先级相同，能够反映网络因为拥塞导致的丢包现象。如果业务报文的优先级变化，则发送LB请求报文和LB响应报文的优先级同样跟随变化，即保持同LSP业务优先级一致即可。In this embodiment, the priority of sending the LB request message and the LB response message is set to be the same as that of the LSP service message, which can reflect the packet loss phenomenon caused by the network congestion. If the priority of the service message changes, the priority of sending the LB request message and the LB response message also changes accordingly, that is, it only needs to be consistent with the service priority of the LSP.
步骤305，源PTN设备根据记录的相邻两个PTN设备同一周期内发送LB响应报文的条数，计算相邻两个PTN设备之间的链路的丢包数，当计算的丢包数为0时，确定该相邻两个PTN设备之间链路性能正常；当计算的丢包数不为0时，确定该相邻两个PTN设备之间链路性能劣化。Step 305, the source PTN device calculates the number of lost packets on the link between the two adjacent PTN devices according to the recorded number of LB response messages sent by the two adjacent PTN devices in the same cycle, when the calculated number of lost packets When it is 0, it is determined that the link performance between the two adjacent PTN devices is normal; when the calculated packet loss number is not 0, it is determined that the link performance between the two adjacent PTN devices is degraded.
本步骤中源PTN设备根据记录的相邻两个PTN设备同一周期内发送LB响应报文的条数，计算相邻两个PTN设备之间的链路的丢包数，包括：In this step, the source PTN device calculates the number of lost packets on the link between the two adjacent PTN devices according to the recorded number of LB response messages sent by the two adjacent PTN devices in the same cycle, including:
当相邻两个PTN设备为源PTN设备和中间PTN设备时，相邻两个PTN设备之间的链路的丢包数为，源PTN设备发送LB请求报文的条数，与记录的接收的该中间PTN设备发送的LB响应报文的条数的差值；When the two adjacent PTN devices are the source PTN device and the intermediate PTN device, the number of lost packets on the link between the two adjacent PTN devices is, the number of LB request packets sent by the source PTN device, and the number of records received The difference in the number of LB response messages sent by the intermediate PTN device;
当相邻两个PTN设备为两个中间PTN设备，或，中间PTN设备和目的PTN设备时，相邻两个PTN设备之间的链路的丢包数为，记录的所述两个PTN设备发送LB响应报文的条数的差值。When the two adjacent PTN devices are two intermediate PTN devices, or the intermediate PTN device and the destination PTN device, the number of packets lost on the link between the two adjacent PTN devices is, the recorded two PTN devices The difference between the number of LB response packets sent.
仍以图2为例，当相邻两个PTN设备为PTN设备1和PTN设备2时，PTN设备1和PTN设备2之间的链路丢包数为：S-R1；S为PTN设备1发送LB请求报文的条数，R1为PTN设备返回LB响应报文的条数。Still taking Figure 2 as an example, when the two adjacent PTN devices are PTN device 1 and PTN device 2, the number of lost packets on the link between PTN device 1 and PTN device 2 is: S-R1; S is PTN device 1 The number of LB request messages sent, and R1 is the number of LB response messages returned by the PTN device.
当相邻两个PTN设备为PTN设备3和PTN设备4时，PTN设备3和PTN设备4之间的链路丢包数为：(S-R4)-((S-R3)-((S-R2)-(S-R1))-(S-R1))-((S-R2)-(S-R1))-(S-R1)＝R4-R3，其中，R2、R3、R4分别为PTN设备2、PTN设备3和PTN设备4返回LB响应报文的条数。When the two adjacent PTN devices are PTN device 3 and PTN device 4, the link packet loss number between PTN device 3 and PTN device 4 is: (S-R4)-((S-R3)-((S -R2)-(S-R1))-(S-R1))-((S-R2)-(S-R1))-(S-R1)=R4-R3, wherein R2, R3, R4 are respectively Return the number of LB response packets for PTN device 2, PTN device 3, and PTN device 4.
本实施例中为了避免LSP路由上的MIP所在PTN设备不能终结和响应LM/DM报文这一固有机制，以及难于针对不在本地终结的LSP进行收发报文性能计数统计，导致不能实现丢包的测量；而是通过对LB机制进行扩展，继承了其中间维护节点能够收发LB报文这一特点，通过提高LB报文的收发速率，由初始发送节点对收发报文进行计数统计实现丢包测量，来准确定位性能劣化的位置。In this embodiment, in order to avoid the inherent mechanism that the PTN equipment where the MIP on the LSP is located cannot terminate and respond to LM/DM messages, and it is difficult to perform statistics on sending and receiving messages for LSPs that are not terminated locally, resulting in the inability to realize packet loss Measurement; instead, by extending the LB mechanism, it inherits the feature that the intermediate maintenance node can send and receive LB messages. By increasing the sending and receiving rate of LB messages, the initial sending node counts the sent and received messages to achieve packet loss measurement. , to accurately locate the location of performance degradation.
基于同样的发明构思，本申请还提出一种实现PTN性能劣化定位系统。参见图4，图4为本申请实施例中实现PTN性能劣化定位系统示意图。该系统包括：源PTN设备、中间PTN设备和目的PTN设备；其中，源PTN设备为源维护终结点MEP所在的PTN设备，中间PTN设备为维护中间点MIP所在的PTN设备，目的PTN设备为目的MEP所在的PTN设备；Based on the same inventive idea, this application also proposes a system for locating PTN performance degradation. Referring to FIG. 4 , FIG. 4 is a schematic diagram of a system for locating PTN performance degradation in an embodiment of the present application. The system includes: source PTN equipment, intermediate PTN equipment, and destination PTN equipment; among them, the source PTN equipment is the PTN equipment where the source maintenance termination point MEP is located, the intermediate PTN equipment is the PTN equipment where the maintenance intermediate point MIP is located, and the destination PTN equipment is the destination PTN equipment. PTN equipment where the MEP is located;
源PTN设备，使用快速报文发送周期发送环回LB请求报文；接收中间PTN设备和目的PTN设备发送的LB响应报文，并分别记录每个周期内接收到的中间PTN设备，以及目的PTN设备发送的LB响应报文的条数；根据记录的相邻两个PTN设备同一周期内发送LB响应报文的条数，计算相邻两个PTN设备之间的链路的丢包数，当计算的丢包数为0时，确定该相邻两个PTN设备之间链路性能正常；当计算的丢包数不为0时，确定该相邻两个PTN设备之间链路性能劣化；The source PTN device sends a loopback LB request message using the fast message sending cycle; receives the LB response message sent by the intermediate PTN device and the destination PTN device, and records the received intermediate PTN device and destination PTN in each cycle The number of LB response messages sent by the device; according to the recorded number of LB response messages sent by two adjacent PTN devices in the same cycle, calculate the number of lost packets on the link between two adjacent PTN devices. When the calculated packet loss number is 0, it is determined that the link performance between the two adjacent PTN devices is normal; when the calculated packet loss number is not 0, it is determined that the link performance between the two adjacent PTN devices is degraded;

较佳地，Preferably,
源PTN设备，具体用于根据记录的相邻两个PTN设备同一周期内发送LB响应报文的条数，计算相邻两个PTN设备之间的链路的丢包数时，当相邻两个PTN设备为源PTN设备和中间PTN设备时，相邻两个PTN设备之间的链路的丢包数为，源PTN设备发送LB请求报文的条数，与记录的接收的该中间PTN设备发送的LB响应报文的条数的差值；当相邻两个PTN设备为两个中间PTN设备，或，中间PTN设备和目的PTN设备时，相邻两个PTN设备之间的链路的丢包数为，记录的所述两个PTN设备发送LB响应报文的条数的差值。The source PTN device is specifically used to calculate the number of lost packets on the link between two adjacent PTN devices based on the recorded number of LB response packets sent by two adjacent PTN devices in the same period. When two PTN devices are the source PTN device and the intermediate PTN device, the number of lost packets on the link between two adjacent PTN devices is, the number of LB request messages sent by the source PTN device, and the recorded received intermediate PTN The difference between the number of LB response messages sent by the device; when two adjacent PTN devices are two intermediate PTN devices, or the intermediate PTN device and the destination PTN device, the link between two adjacent PTN devices The number of lost packets is the recorded difference between the number of LB response messages sent by the two PTN devices.
