Abstract

The invention provides a service chain drainage method and device. A security port which is connected with a security device is removed from all VLANs. The functions of input and output rule checking and address learning of the security port are closed, so that flow flooding on the security device is prevented, and a forwarding path is not affected by flow output. Through a flow entrance sign, output flow is prevented from being forwarded from an original input port. According to the invention, a service chain drainage scheme is provided; the security device is in a transparent mode; and the problems of performance bottlenecks, single point faults and poor scalability of a traditional deployment manner are solved.

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...
