In-cloud east-west traffic traction method and system based on an SDN (Software Defined Network)

Abstract

The invention provides an in-cloud east-west traffic traction method and system based on an SDN (Software Defined Network), and realizes integration of in-cloud traffic acquisition and management. The system comprises a flow acquisition module, an integrated controller module and a Web management module. The method comprises the following steps: deploying a flow collection module in a virtual machine form on each host machine of a cloud platform, calling an open interface of the cloud platform by a web management module to obtain a host machine and virtual machine list, and selecting a host machine or a virtual machine needing to be monitored on a page provided by the web management module; issuing a port mirroring strategy to a cloud platform through a rest interface by a web management module, and mirroring virtual machine traffic clicked by a user to a traffic collection module deployed in a current host machine; and collecting and analyzing the flow. According to the invention, the SDN controller manages the collection equipment and the cloud platform in a centralized manner, carries out unified scheduling from a global perspective, and perceives the migration of the virtual machine, can collect the east-west flow in the virtual environment, reduces the collection of unnecessary flow, and relieves the performance pressure.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to an SDN-based east-west flow pulling method and system in a cloud. Background technique [0002] The proportion of cloud services in various industries in my country is increasing. Since 2017, more than 70% of my country's provinces and cities have introduced policies to promote local enterprises to accelerate their migration to the cloud. After enterprises go to the cloud, they no longer use physical machines to deploy services on a large scale. Most of them use virtualization technology to manage computing resources in a unified pool. At this time, the traffic between business interactions between different virtual machines on the same physical machine no longer passes through the network. physical switch. The traffic collection scheme of the traditional data center is very mature, but the implementation of traffic collection in the cloud environment faces the fol...

However, in the cloud environment, most servers are accessed through 10G or 20G high-density access. Since switch mirroring can only collect all traffic based on interfaces and cannot be filtered, it will affect performance and stability.

Third, after the virtual machine is migrated, the static image policy cannot be migrated synchronously.
