Embodiment Construction

[0055] The present invention will be further described in detail in conjunction with the following specific embodiments and accompanying drawings. The process, conditions, experimental methods, etc. for implementing the present invention, except for the content specifically mentioned below, are common knowledge and common knowledge in this field, and the present invention has no special limitation content.

[0056] The present invention comprises the following steps:

[0057] controller connection switch

[0058]The controller is connected to the switch, and the two establish a TCP channel. When the controller first receives a registration message from a switch (based on the Openflow protocol or other SDN protocols), it will install a flow table. The match information and actions of this flow table are as follows:

[0059] matches

priority

action

All

0

To controller

[0060] This is a flow table with a priority of 0 that matches all flows...

Abstract

The invention discloses an SDN multi-controller extensible cooperation method. The method, on the basis of maintaining basic performance of a network, greatly improves extensibility of the network, and comprises the steps of selecting different network roles; establishing an in-band control channel; carrying out abstraction and view establishment; and carrying out route forwarding on the basis of hierarchical topology and the like. The method solves the problem that it is hard for a conventional single controller to apply in a large-scale network. The main achievements are that the method can be implemented under existing hardware conditions, reduces network synchronization overhead and enables an SDN to be able to be applied in the large-scale network.

Description

technical field [0001] The invention belongs to the field of network technology, in particular to a multi-controller scalable coordination method of a software-defined network (SDN). Background technique [0002] The software-defined network is a revolution point of the modern network, and it is proposed for the deficiencies of the modern network in the face of the modern complex and changeable network environment and network requirements. It is a design mechanism of overthrowing and starting over, abandoning the distributed infrastructure of traditional networks, proposing a method of separating the control plane and data forwarding plane, and adopting a centralized control method to obtain unimaginable flexibility of traditional networks. However, because of the centralized control of SDN, if one control core is still used when it is applied to a wide area network, the load on the controller will become extremely large, and at the same time, the control delay will be great...
