A gateway group method and system based on SDN framework

Abstract

The invention discloses a gateway group system and method based on an SDN framework. The system includes: a control plane module, which receives gateway group configuration information, and sends the gateway group configuration information to a network bridge management module; and a network bridge management module, according to the gateway group configuration information Create a bridge and trigger the bridge addition event to notify the flow table processing module; the flow table processing module, after listening to the bridge addition event, uses the standard southbound interface of the SDN framework to push the flow table to the connected OpenvSwitch to complete Issuance of the flow table, the flow table issued by the gateway node is responsible for the forwarding of north-south traffic, the flow table issued by the computing node contains the OpenFlow group flow table, and is responsible for the forwarding of virtual machine traffic from the computing node to the gateway node; the gateway group improves It improves the processing efficiency of the message, and solves the problems of performance degradation caused by the traditional single-node gateway processing data center north-south traffic, low error redundancy and complex user configuration.

Description

technical field [0001] The invention relates to the technical field of gateway group design, in particular to a gateway group method and system based on an SDN framework. Background technique [0002] With the rapid development of computer technology and integrated circuit technology, cloud computing has become a new trend in enterprise IT construction due to its advantages in high system utilization, low manpower / management costs, and strong flexibility / expandability. However, in terms of network, the traditional network cannot meet the characteristics of data-neutral network virtualization and the concept of NaaS (Network as a Service). [0003] As a new network innovation architecture, SDN (Software Defined Network) solves the problem of network virtualization with a new design concept and has achieved good and rapid development. It has fully possessed the technical maturity that can be applied in the product environment; and in In cloud computing, massive adoption and d...
