Network deployment for OVS and Linux bridge in SDN new-type network

Abstract

The invention discloses network deployment for OVS and Linux bridge in an SDN new-type network. An SDN controller can directly manage and control an OpenFlow hardware switch, so physical servers connected with the OpenFlow hardware switch can communicate through the SDN network. The SDN controller also can permeate into a Linux kernel by taking a traditional switch device as a medium and manages and controls an Open vSwitch and Linux bridges. For the OVS, a flow table rule is directly issued, a corresponding policy is made, fine-grained networking planning is carried out on a virtual network,network bridge virtualization is carried out on a Linux network protocol stack, various network bridges are virtualized, and network connection among virtual machines is realized. A control module formanaging and controlling the Linux bridges is added to the SDN controller, so the control over the Linux kernel is directly realized, and the flexible switching between the OVS and Linux bridges is realized. The network deployment is applicable to a universal and expandable cloud network scene.

Description

technical field [0001] The invention relates to the field of network deployment, in particular to the network deployment of OVS and Linux bridge in a new SDN network. Background technique [0002] With the widespread application of the new SDN network architecture in data centers, data centers, as centralized pools of enterprise IT resources, are the centers of data calculation, network transmission, and storage, and networks, as modules that provide data exchange, are the core of data centers. One of the infrastructure, it is directly related to the performance, scale, scalability and manageability of the data center. The data center network with traditional network equipment as the core has been difficult to adapt to the rapid deployment, flexible management and control of businesses and networks by enterprises and users. As a new network architecture, SDN separates control and forwarding, and abstracts the control plane to centralize control and flexibly manage the cloud...

Problems solved by technology

[0004] Users still rely on traditional networks. At the same time, enterprises or individuals can temporarily meet their needs on traditional network equipment, but when it is necessary to expand new services or add new equipment for deployment, the flexibility of the traditional network architecture is not good, and the deployment is not easy. Disadvantages such as flexibility and inconvenient configuration will gradually be exposed

At the same time, in order to operate computing and network resources more flexibly, enterprises and institutions gradually tend to shift to the cloud, build their own private clouds or even rent public clouds to meet the business needs of units and departments, but they still face rapid deployment and flexible configuration question
