System and method for implementing dynamic load sharing function of network service access under nfv architecture

Abstract

The present invention relates to a system and method for realizing dynamic load sharing function of network service access under NFV framework, including several access nodes and several edge nodes, both of which are VNF nodes, and each VNF node is connected with The internal networks of the system are all connected, and the edge node is connected to the external remote user module, and periodically multicasts its own IP address to the access node, and the edge node calculates its IP address based on the received load status of the access node. Load indicators, and select a suitable access node for the external remote user module to access; the access node is connected to each edge node, and is used to periodically unicast the real-time load status of itself through the protocol message to the edge node, and record the IP address of the edge node in the current network. Adopting the invention can avoid realizing load sharing of user access under the NFV architecture through a proprietary load balancer, and can realize dynamic expansion and contraction of VNF resources at the same time.

Description

technical field [0001] The present invention relates to the field of NFV, in particular to the technical field of NFV architecture system, and specifically refers to a system and a method thereof for realizing the dynamic load sharing function of network service access under the NFV architecture. Background technique [0002] In the NFV architecture system, network administrators can create and delete virtual containers in the virtual resource pool to carry user access services. This can be called VNF. A common method is: create a certain amount of VNFs in advance, and select VNFs in order to go online when users access. When the VNF reaches the upper limit of user access capacity, select the next idle VNF or create a new VNF. When the number of users access reaches a certain amount, some users will inevitably go offline. These users may be connected on any VNF, so some VNFs will be fully loaded and some VNFs will be idle. If there are new users to access in the future, th...
