Method for Realizing Virtual Programmable Router under Separation Architecture of Forwarding and Control

Abstract

The invention discloses a method achieving virtual programmable router under a framework of forwarding and control separation. The method achieving the virtual programmable router under the framework of forwarding and control separation comprises the following steps: receiving an instruction which creates the virtual programmable router instruction by a control part management unit receiving user, and calculating the number and the parameter of virtual control parts and virtual forwarding parts and corresponding relations between the virtual control parts and the virtual forwarding parts; informing each control part by the control part management unit to create the virtue control parts which are needed, and informing each forwarding parts through a forwarding part management unit to create the virtual forwarding parts which are needed; informing the corresponding relations to the virtual control parts and virtual forwarding parts; requesting chain building to the virtual control parts through a ForCES protocol according to the corresponding relations, and achieving a single virtual programmable router which is composed of a plurality of the virtual control parts and a plurality of the virtual forwarding parts; and achieving management and maintenance of the virtual programmable router by units. The method achieving the virtual programmable router under the framework of forwarding and control separation improves the flexibility, the dynamics, the expandability and the manageability of a physical router, and overall performance of the router can be improved through load balancing.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a method for realizing a virtual programmable router under the forwarding and control separation framework. Background technique [0002] As we all know, problems such as address shortage, QoS, security, and IP multicast that the Internet has been facing for a long time have not been effectively resolved. The root cause is that the Internet's huge scale and complex and heterogeneous management system make it difficult to deploy and apply technologies such as IPv6, DiffServ, secure routing, and PIM-SM on a large scale, resulting in the rigidity of Internet technology innovation. Network virtualization is the key to solving the current Internet rigidity problem. Its core idea is to separate the two functions of network service provision and infrastructure provision on the basis of resource virtualization. Construct multiple independent and non-interfering virtual network p...
