Problems solved by technology

like figure 1 In the service chain from client to server shown, DN first sends the service flow to SN1, SN1 processes the service flow and then returns the processed service flow to DN, and DN sends the service flow processed by SN1 to SN2, SN2 returns to DN after processing the service flow, and DN sends the service flow processed by SN1 and SN2 to SN3, and SN3 returns to DN after processing the service flow. In the above method, as long as a certain value-added If a service node fails, such as SN1 downtime, the service chain from client to server will be interrupted. It can be seen that the reliability of the service chain in the prior art is very low

Abstract

The embodiment of the present invention discloses a service chain management method, flow point, controller and value-added service node, wherein one method includes: the entry flow point of the service chain receives the detection message of the service chain, and the service chain It includes at least one value-added service node, and the detection message carries status information of each value-added service node; the entry diversion point judges whether the service chain is in a normal operation state according to the detection message. By adopting the invention, the management of the service chain can be realized, thereby improving the reliability of the service chain.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a management method of a service chain, a diversion point, a controller and a value-added service node. Background technique [0002] Data center refers to a complete set of integrated IT application environment that realizes centralized processing, storage, transmission, exchange and management of data information in a physical space. In the current data center network, the deployment of value-added service equipment, such as firewalls, intrusion prevention systems (English: Intrusion Prevention System, IPS for short), etc., is closely related to the network topology. The close correlation between value-added services and network topology leads to value-added The deployment of business equipment is extremely inflexible. Therefore, in order to flexibly deploy value-added service equipment in the data center network, a service chaining (English: service chaining) technolog...
