Problems solved by technology

The setting of a flow entry takes about 10~20ms, which will cause network delay
[0009] 2. Group table overflow problem
Migration to switches that can only accommodate a few thousand flow entries due to the high cost of TCAM
When the number of entries of the flow entry exceeds the storage capacity of the flow table, the group table overflow problem occurs

Embodiment Construction

[0067] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0068] In the SDN network architecture, the control plane and the forwarding plane are separated, the management and status of the network are logically centralized, and the underlying network foundation is independent from the application. As a result, the network obtains unprecedented programmable, controllable and automated capabilities . This allows users to easily build highly scalable and elastic networks based on business needs. Based on the SDN network architecture, operators can control the forwarding path of user traffic and realize customized mobile service links.

[0069] To realize the transfer-control separation architecture of the SDN network, it is necessary to establish a communication interface standard between the SDN controller and the data forwarding layer. OpenFlow is a standard protocol of SDN, which allows the controller to directly ...

Abstract

The invention relates to a service chain grouping and reforming method for mobile edge calculation, which comprises the following steps of: S1, establishing a mobile edge calculation system; S2, judging whether the edge node can provide the service function of the received service chain required by the user equipment or not by the Hash group manager of the edge node; S3, configuring all service functions in the service chain at the edge node; S4, configuring a part of service functions in the service chain at an edge node, and configuring the remaining service functions at a core network node; S5, configuring all service functions in the service chain at the core network node; and S6, reforming the group nodes. According to the scheme, user equipment requirements are grouped, one group only needs to be configured with one group of service chains, and users in the group share the service chains, so that the usage amount of flow entries when the service chains are configured is reduced, the possibility of group table overflow is reduced, the number of times of information exchange between edge nodes and core network nodes is reduced. Therefore, the delay of the control layer is reduced.

Description

technical field [0001] The invention belongs to the technical field of communication control, in particular to a service chain grouping and reorganization method of mobile edge computing. Background technique [0002] The core design of the SDN (Software Defined Network) architecture is the separation of the control plane and the forwarding plane. The typical architecture of an SDN network is generally divided into three layers, which are the application layer, the control layer, and the data forwarding layer from top to bottom. In practical applications, network administrators can send network policies to the control layer through the application layer for network policy configuration, so that users can program, so the rapid response based on application and traffic changes does not need to be completely dependent on The equipment supplier's long-term software and hardware upgrades are completed. Since SDN migrates the control function from the traditional distributed netw...
