SDN framework-based flow table configuring and delivering method and system

Abstract

The invention discloses an SDN framework-based flow table configuring and delivering method and system. The method comprises the steps of receiving configuration information of a floating IP, wherein the configuration information comprises a binding relationship of the floating IP and a network adapter ID of a corresponding virtual machine; determining, by using an SDN framework, whether the virtual machine runs according to the configuration information; and if the virtual machine runs, configuring and delivering a flow table to a virtual exchange corresponding to the virtual machine. According to the method, the flow table is configured and delivered to the virtual exchange corresponding to the virtual machine by using the SDN framework according to running condition of the configuration information in the virtual machine; due to use of characteristics of efficiency, programming and good expandability of the SDN framework, the learning cost of the user and configuration complexity are lowered to a great extent, and great flexibility is ensured, so that the virtual exchange can process the packet according to the flow table, the virtual machine realizes a south-north communication function through the floating IP, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of computer application technology, in particular to a method and system for delivering flow table configuration 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 and management costs, and strong flexibility and scalability. However, in terms of network, the traditional network can no longer meet the characteristics of data center network virtualization. [0003] In cloud computing, massive adoption and deployment of virtualization is a fundamental technology paradigm. The extensive deployment of server virtualization technology has greatly increased the computing density of the data center; at the same time, in order to achieve business flexibility, some virtual machine VM (Virtual Machin...

[0004] In the prior art, although the north-south traffic in the data center can be implemented through a virtual switch (OpenvSwitch, OVS), that is, the network address translation of the virtual machine is completed through the virtual switch. With the support of the virtual switch for the flow table, the user can control it through the flow table. Traffic capture and message processing, but users need to configure the flow table supported by the virtual switch according to the floating IP to complete the flow table distribution process, which undoubtedly greatly increases the user's learning cost and configuration complexity, which is not conducive to users to experience
