Problems solved by technology

Since the IETF ForCES working group has always defined its technology in a network device node, the ForCES technology has not been well promoted to applications like cloud computing networks, which limits its attention and influence in the industry

Embodiment

[0040] In order to make it easier for those skilled in the art to understand and realize the present invention, the technical solution of the present invention will be further described in conjunction with the accompanying drawings, and a specific embodiment of the method described in the present invention will be given.

[0041] 1) Overall scheme design

[0042] The present invention adopts a control part and a forwarding part to realize the extension plug-in of ForCES, and realizes the three-layer forwarding function of Neutron based on the ForCES plug-in, and realizes the distributed routing function by deploying the plug-in agent in each computing node, so that OpenStack Only the north-south traffic goes through the network nodes, while the east-west traffic does not need to go through the network nodes, and is directly forwarded by the plug-in agent on the computing node. Such as figure 1 As shown, the control part is deployed on the control node and is composed of a dat...

Abstract

The invention discloses a software-defined network realization method based on ForCES. In the present invention, based on the SDN framework of Neutron, an implementation scheme based on ForCES extension plug-in is proposed. The basic architecture of ForCES extension plug-in includes two parts: plug-in and plug-in agent. The plug-in creates a three-layer route through message interaction with Neutron, and converts the user's attribute operation on the logical function block into a specific operation on the virtual network, routing, and network interface. The plug-in agent is located on the network node and computing node. The container of the logical function block entity is used to realize the network layer processing of the data packet; the present invention also provides the design and modeling method of the relevant IETF ForCES logical function block, so that the user can conveniently use the northbound interface provided by the ForCES extension plug-in Redefining the Openstack network.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a ForCES-based software-defined network implementation method. Background technique [0002] Cloud computing is a new revolution in the information technology industry, and another important technological revolution after the computer revolution and the Internet revolution. The emergence of cloud computing means that people can use the virtual resources of the Internet, users can manage and control the purchased services, and can obtain on-demand network resources in a multi-tenant environment through cloud computing. Because the network is only a part of service deployment. In addition to the network, it is also necessary to allocate computing resources, storage resources, etc. for the business. If there is a platform that can centrally manage these resources, and when the virtual machine needs to be changed (add, delete, migrate), you only need to input the reso...
