Embodiment Construction

[0043] figure 1 It is a system architecture diagram of a business chain combination method proposed in the prior art, such as figure 1 As shown, the method in the prior art mainly involves a strategy map editor / viewer, a strategy map combiner, a software-defined networking (software-defined networking, SDN) controller, and a rule detector. The functions of each part are as follows:

[0044] Policy graph editor / viewer: mainly responsible for receiving network policy request information. Network policy is described in the form of a graph consisting of nodes and edges, where nodes represent terminal sets, and edges represent communication links (including service chains).

[0045] Strategy map combiner: mainly combines the input strategies.

[0046] SDN controller: Generate forwarding rules based on the result of policy combination.

[0047] Rule detector: Responsible for checking whether the generated forwarding rules will conflict with the deployed rules.

Abstract

The present application provides a service chain processing method, related network element and system, the method includes: a first network element receives a first request message, the first request message includes a first service chain, if the first service chain and the The second service chain that has been deployed in the network can be aggregated, then the first network element according to the input packet space of the first service chain, the output packet space and the matching space of the network function unit and the second service chain. The matching space of the input packet space, the output packet space and the network functional unit determines the aggregation order of the first service chain and the second service chain, and then the first network element generates a third service chain according to the aggregation order. A service chain, the third service chain includes the first service chain and the second service chain. The aggregated business chain obtained by this method conforms to specific application scenarios, so as to avoid the problem of abnormal deployment of the business chain.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a service chain processing method, related network elements and systems. Background technique [0002] The fifth generation (fifth generation, 5G) network is a new generation of communication network. The 5G network requires flexibility and customization to meet various business scenarios and network requirements. Among them, customized network strategy is an important function supported by 5G network. Specifically, the system architecture of the 5G network includes an application function (application function, AF) network element and a policy control function (policy control function, PCF) network element. Among them, the terminal can request the required network policy through the AF network element, and further process it through the PCF network element, and automatically deploy the network policy to the network to meet the terminal's demand for customiz...
