Abstract

The present invention provides a service chain drainage method and device. By removing the security port connected to the security device from all VLANs, turning off the input and output rule check of the security port and the address learning function of the security port, the traffic will not flow in the security device. Flooding does not affect the forwarding path when the traffic is output, and prevents the traffic from being forwarded from the original input port when the traffic is output through the ingress mark of the traffic. It provides a service chain drainage solution in which the security device is transparent mode, which solves the traditional deployment method. There are performance bottlenecks, single point of failure and poor scalability.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a service chain drainage method and device. Background technique [0002] The deployment of security devices for traditional network egress is as follows: figure 1 As shown, the traditional deployment method has the following problems: [0003] 1. Performance bottleneck [0004] The deployment in series requires traffic to pass through all devices, and the network node with the worst performance will become the bottleneck of the entire chain. However, current security devices have limited processing capabilities and cannot keep up with the speed of traffic growth. [0005] 2. Single point of failure [0006] The series deployment mode makes the entire network unable to work properly when a node on the path fails. [0007] 3. Poor scalability [0008] When a security device needs to be added, the topology needs to be changed, causing the entire network to...
