Embodiment Construction

[0063] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0064] The system for realizing the dynamic load sharing function of network service access under the NFV architecture of the present invention includes several access nodes and several edge nodes, and both the access nodes and the edge nodes are VNF nodes, Each of the VNF nodes described is connected to the internal network of the system, wherein:

[0065] 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 the IP address according to the received load status of the access node. The load indicator of the access node described above, and select the corresponding access node for the external remote user module;

[0066] The access node is connected to each of the edge nodes, and is used to periodically...

Abstract

The invention relates to a system and a method for realizing a network service access dynamic load sharing function under an NFV architecture. The system comprises a plurality of access nodes and a plurality of edge nodes, wherein the access node and the edge node are both VNF nodes; each VNF node is connected with an internal network of the system; wherein the edge node is connected with an external far-end user module, the IP address of the edge node is periodically multicast to the access node, and the edge node calculates the load index of the edge node according to the received load stateof the access node and selects an appropriate access node for the external far-end user module to access; And the access node is connected with each edge node and is used for periodically sending thereal-time load state of the access node to the edge nodes in a unicast manner through protocol messages and recording the IP addresses of the edge nodes in the current network. By adopting the methodand the device, load sharing of user access under the NFV architecture can be avoided through a special load balancer, and meanwhile, dynamic capacity expansion and shrinkage of VNF resources can berealized.

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...
