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 service chain grouping and reorganization method of mobile edge computing includes the following steps: step S1, establish a mobile edge computing system; step S2, the hash group manager of the edge node judges whether the edge node can provide the received user equipment The service functions of the required service chain; step S3, all service functions in the service chain are configured on edge nodes; step S4, part of the service functions in the service chain are configured on edge nodes, and the remaining service functions are configured on core network nodes; step S5 , all service functions in the service chain are configured on the core network nodes; Step S6, reorganize the group nodes. In this solution, user equipment requirements are grouped. A group only needs to configure a set of service chains, and users in the group share this service chain. Therefore, the usage of flow entries when configuring service chains is reduced, and the possibility of group table overflow is reduced. Reliability, as well as the number of information exchanges between edge nodes and core network nodes, thereby reducing the delay in the control layer.

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...
