本发明涉及通信领域，尤其涉及一种业务流传输的方法和设备。The present invention relates to the field of communications, and in particular, to a method and device for service stream transmission.
背景技术Background technique
运营商核心网设备云化之后，主要存在两种网络转发模式。一种是硬直通方式，也就是SR-IOV(Single-Root I/O Virtualization)方式，这种方式是虚拟机监视器Hypervisor将物理网卡虚拟出多个虚拟网卡，利用数据平面开发套件DPDK(Data PlaneDevelopment Kit)或者其他技术使虚拟功能直通给虚拟机VM使用。另一种是虚拟交换vSwitch(Virtual Switch)。方式，其本质是软件交换，云化的操作系统利用中断或者轮询的等手段将网卡收发的报文在虚拟机VM之间进行交换传递。vSwitch方式的的转发能力整体较SR-IOV方式弱一些，部分商用的虚拟交换机转发能力在几百Kpps左右，所以当网络出现流量突发的情况下，vSwitch往往容易成为端到端的转发瓶颈。一旦出现转发瓶颈之后，vSwitch当前无法做到高优先级报文的优先保障。比如数据流量和VoLTE语音报文，可能同时受到无差别丢弃，导致端到端高优先级报文无法得到有效保障。高优先级的报文可能反而被丢弃，丢弃原因主要是vSwitch当前无法有效获取到数据流的优先级级别，因而无法进一步进行有效地高优先级处理。After the operator's core network equipment is cloudified, there are mainly two network forwarding modes. One is the hard pass-through method, which is the SR-IOV (Single-Root I/O Virtualization) method. In this method, the virtual machine monitor Hypervisor virtualizes the physical network card into multiple virtual network cards, and uses the data plane development kit DPDK (Data PlaneDevelopment Kit) or other technologies to make the virtual function pass-through to the virtual machine VM. The other is virtual switching vSwitch (Virtual Switch). The essence of the method is software switching. The cloud-based operating system uses interrupts or polling to exchange and transmit the packets sent and received by the network card between virtual machines and VMs. The forwarding capability of the vSwitch mode is generally weaker than that of the SR-IOV mode. The forwarding capability of some commercial virtual switches is around several hundreds of Kpps. Therefore, when the network bursts with traffic, the vSwitch tends to become an end-to-end forwarding bottleneck. Once a forwarding bottleneck occurs, the vSwitch cannot currently guarantee the priority of high-priority packets. For example, data traffic and VoLTE voice packets may be discarded indiscriminately at the same time, so that end-to-end high-priority packets cannot be effectively guaranteed. High-priority packets may be discarded instead. The reason for the discarding is that the vSwitch cannot effectively obtain the priority level of the data stream, and therefore cannot further effectively process high-priority packets.
运营商网络中数据报文优先级标示可以通过链路层VLAN(Virtual Local AreaNetwork，虚拟局域网)优先级以及网络层的DSCP(Differentiated Service Code Point，差分服务码点)进行，或网关设备中通过业务质量QoS(Quality of Service)标示。核心网设备云化之后vSwitch可以识别VLAN优先级或者DSCP进行调度决策。为了保障在接收报文端vSwitch同样能够进行优先级差异处理，那么首先需要给报文优先级级别标识。The priority marking of data packets in the operator network can be performed through the link layer VLAN (Virtual Local Area Network, virtual local area network) priority and the network layer DSCP (Differentiated Service Code Point, Differentiated Service Code Point), or through the gateway device. Quality QoS (Quality of Service) mark. After the core network devices are cloudized, the vSwitch can identify VLAN priorities or DSCP to make scheduling decisions. To ensure that the vSwitch on the receiving end can also process the priority difference, you need to first identify the priority level of the packets.
传统的报文DSCP或者VLAN优先级标记方法是由报文发出端，通常即应用服务器来填写相应的DSCP值或者VLAN优先级，该方法由于服务器发送报文端不受运营商设备控制，无法准确体现服务差异，因此不能很好地进行业务质量控制。The traditional packet DSCP or VLAN priority marking method is that the sender of the packet, usually the application server, fills in the corresponding DSCP value or VLAN priority. This method cannot be accurate because the server sending the packet is not controlled by the operator's equipment. It reflects service differences, so it can't carry out business quality control very well.

An example of the service flow priority parameter is shown in Table 1 below, and each service flow identifier corresponds to a corresponding priority.
表1，业务流优先级参数示例Table 1, example of business flow priority parameters
或者，201b–202b，配置优先级的另一个方式是策略控制设备根据应用服务器的请求而发送相关业务流优先级参数。例如，步骤201b，策略控制设备收到应用服务器发送的diameter协议的鉴权认证请求AAR(Authentication-Authorization-Request)消息后，在步骤202b返回鉴权认证响应AAA(Authentication-Authorization-Answer)消息中，携带相关业务流优先级信息，包括DSCP参数或者VLAN优先级参数以及对应的流信息。Or, 201b-202b, another way of configuring the priority is that the policy control device sends the relevant service flow priority parameter according to the request of the application server.

应用于上述图1所示的系统中，本发明的实施例提供了另一种业务流传输的方法。如图3所示，策略控制设备将业务流的优先级确定规则配置到应用服务器中，应用服务器根据规则在下发的业务流中携带优先级。具体包括下列步骤：Applied to the system shown in FIG. 1 above, the embodiment of the present invention provides another method for transmitting service flow. As shown in FIG. 3 , the policy control device configures the priority determination rule of the service flow in the application server, and the application server carries the priority in the delivered service flow according to the rule. Specifically include the following steps:
301a-302a，策略控制设备可以主动通知应用服务器业务流优先级确定规则。例如，步骤301a，策略控制设备在向应用服务器发送diameter协议的重鉴权请求RAR(Re-Auth-Request)消息中，携带相关业务流优先级信息，包括业务流确定规则。步骤302a，应用服务器收到RAR消息后，返回重鉴权响应(Re-Auth-Answer)消息。业务流确定规则的一个例子如下面表2，每个业务流类型配置了相应的优先级参数。301a-302a, the policy control device may actively notify the application server of the service flow priority determination rule. For example, in step 301a, the policy control device sends the re-authentication request RAR (Re-Auth-Request) message of the diameter protocol to the application server, carrying relevant service flow priority information, including service flow determination rules. Step 302a, after receiving the RAR message, the application server returns a re-authentication response (Re-Auth-Answer) message. An example of the service flow determination rule is shown in Table 2 below, and corresponding priority parameters are configured for each service flow type.
表2，业务流优先级确定规则示例Table 2, Examples of business flow prioritization rules
或者，301b–302b，策略控制设备也可以根据应用服务器的请求而发送业务流优先级确定规则。例如，步骤301b，策略控制设备收到应用服务器发送的diameter协议的鉴权认证请求AAR(Authentication-Authorization-Request)消息后，在步骤302b返回鉴权认证响应AAA(Authentication-Authorization-Answer)消息中，携带如表2所示的业务流优先级确定规则。，包括DSCP参数或者VLAN优先级参数以及对应的流信息。Alternatively, in 301b-302b, the policy control device may also send the service flow priority determination rule according to the request of the application server. For example, in step 301b, after receiving the authentication-authorization-request AAR (Authentication-Authorization-Request) message of the diameter protocol sent by the application server, the policy control device returns the authentication-authorization-response AAA (Authentication-Authorization-Answer) message in step 302b , carrying the service flow priority determination rules shown in Table 2. , including DSCP parameters or VLAN priority parameters and corresponding flow information.
303，应用服务器收到上述优先级参数后，根据上述表2，如果要向用户下发的业务流，则根据业务类型和表2匹配获得业务优先级参数。在下发的业务流数据中携带所述优先级参数，包括DSCP参数或者VLAN优先级参数。303 , after receiving the above-mentioned priority parameter, according to the above-mentioned Table 2, if the service flow to be delivered to the user is to be delivered, the service priority parameter is obtained by matching the service type with Table 2.
