Problems solved by technology

[0005] Since the virtual switch is an intermediate node on the network traffic transmission path, it cannot judge the overall transmission quality from the source end to the destination end of the network traffic. In the case of a path link failure, the switching of the above-mentioned network traffic transmission path can be realized, and it is impossible to switch the network traffic transmission path when the quality of network traffic transmission is abnormal

Abstract

The invention discloses a method and a system for controlling network flow transmission path switching. The method comprises a virtual switch or a virtual machine base instrument manages a functional entity, and according to path information transmitted by a virtual machine on network flow with transmission quality change, determines a switching plan; the virtual switch switches network flow transmission paths according to the switching plan. The method and the system for controlling network flow transmission path switching can achieve switching of the network flow transmission paths according to the network flow transmission quality.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method and system for controlling network traffic transmission path switching. Background technique [0002] With the development of cloud technology, virtualization technology, as the basic technology of cloud computing, has been widely used in the field of enterprise data centers and large-scale cluster computing. [0003] Virtualization technology virtualizes one computer into multiple virtual logical computers, namely virtual machines (VM). Virtual machines generally use virtual network cards, virtual switches, and server physical network ports connected to switches in the chassis or top-of-rack switches to communicate with the outside of the server. [0004] In order to ensure the reliability of transmission, the virtual switch generally uses at least two server physical network ports to communicate with the outside of the server. At least two server physical n...
