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. like figure 1 As shown, the control part is deployed on the control node and is composed of a databa...

Abstract

The invention discloses a software defined network realization method based on ForCES (Forwarding and Control Element Separation). According to the method, on the basis of an SDN frame of a Neutron, a realization scheme based on a ForCES extension plug-in is provided. The basic architecture of the ForCES extension plug-in comprises two parts: the plug-in and plug-in agents. The plug-in establishes a three-layer route through message interaction with the Neutron and converts attribute operation of a user for logic function blocks into specific operation for a virtual network, the route and network interfaces. The plug-in agents are located on network nodes and computing nodes, are containers for placing logic function block entities and are used for realizing network layer processing of data packets. The invention also provides a design and modeling method for related IETF ForCES logic function blocks, a user can redefine an Openstack network conveniently through northbound interfaces provided by the ForCES extension plug-in.

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...
