Gateway group method and system based on SDN framework

Abstract

The present invention discloses a gateway group method and system based on an SDN framework. The system comprises: a control plane module used to receive gateway group configuration information and send the gateway group configuration information to a network bridge management module; the network bridge management module used to create a network bridge according to the gateway group configuration information and trigger a network bridge adding event to inform a flow table processing module; and the flow table processing module used to push a flow table to an OpenvSwitch connected to a standard southbound interface of the SDN framework by the standard southbound interface of the SDN framework to complete the issuing of the flow table after monitoring the network bridge adding event. The flow table issued by a gateway node is responsible for the forwarding of the north-south traffic. The flow table issued by a calculation node contains an OpenFlow group flow table, which is responsible for the forwarding of the virtual machine traffic from the calculation node to the gateway node. Through a gateway group, the efficiency of the message processing is improved and the problems of performance degradation and low error redundancy and complex user configuration caused by the north-south traffic in the traditional single node gateway processing data center are solved.

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...
