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.

The application provides a service chain processing method, related network elements and a system. The method comprises the steps that: a first network element receives a first request message, and the first request message comprises a first service chain; if the first service chain can be aggregated with a second service chain deployed in a network, the first network element determines an aggregation sequence of the first service chain and the second service chain according to an input packet space, an output packet space and a matching space of a network functional unit of the first servicechain and an input packet space, an output packet space and a matching space of a network functional unit of the second service chain; and further, the first network element generates a third servicechain according to the aggregation sequence, and the third service chain comprises the first service chain and the second service chain. By the method, the obtained aggregated service chain accords with a specific application scene so as to avoid a problem of abnormal service chain deployment.
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...
