Message transmission method, service chain system, and computer-readable storage medium

Abstract

The invention discloses a message transmission method, a service chain system and a computer-readable storage medium. The method comprises the following steps: when a service function proxy node receives a network flow message sent by a classifier, if the received network flow message is not the first message of the network flow, obtaining the identification information recorded corresponding to the network flow; if the service function proxy node receives the network flow message sent by the classifier, obtaining the identification information recorded corresponding to the network flow; if the service function proxy node receives the network flow message, obtaining the identification information. If the identification information is the first identification, the optimized transmission path in the service chain path information sent by the service chain controller is obtained, and the network flow message is transmitted in the service chain according to the optimized transmission path.The optimized transmission path is that when the network flow message needs to be transmitted to the next hop of the service chain, the service function proxy node sends the network flow message to the next hop service function node. The invention reduces the forwarding times between the service function node and the service function proxy node which do not support NSH on the service chain, shortens the transmission path of the message in the service chain, reduces the forwarding time delay, and improves the service quality.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a message transmission method, a service chain system and a computer-readable storage medium. Background technique [0002] The value-added service (Value-Added Service, VAS) is more and more abundant. In order to solve the flexible deployment of value-added services, a Service Function Chain (SFC) technology is introduced. In a service chain system, there are multiple service chains, and each service chain is a series of sequential SF (Service Function, business function) sequences. The number, type, and order of SFs on each service chain can be different, and different flows go through different service chains. [0003] When the service chain is deployed, the message needs to be forwarded multiple times between the service function proxy nodes (SFC Proxy) that do not support NSH (Network Service Header, Network Service Header) SF on the service chain, which incre...

Problems solved by technology

[0004] The main purpose of the present invention is to provide a message transmission method, a service chain system, and a computer-readable storage medium, aiming at solving the problem of multiple message transmission between service function nodes that do not support NSH on the service chain and service function agent nodes. Repeated forwarding increases the consumption of network bandwidth and forwarding delay, resulting in technical problems of service quality degradation
