Abstract

The invention belongs to the technical field of communication, and specifically discloses a large-scale SDN controller cluster and a network system. The cluster comprises an SDN controller group; a buffering server group which is used for storing the control data of the SDN controller group, wherein the control data at least comprises configuration information, a control rule, routing informationand topological data. According to the invention, the control logic and data storage of the SDN controller are separated, i.e., enabling the data storage to be set in one distributed buffering system.Each SDN controller just has the control logic, and does not has the data storage, so the redundancy of data does not increase all the time when the large-scale SDN controller cluster is needed. Also, different types of SDN control data can be placed in different buffering systems, thereby achieving the lateral expansion of data storage.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a large-scale SDN controller cluster and a network system. Background technique [0002] The SDN controller is the core of the SDN (Software Defined Network) network. It is mainly responsible for the centralized control of the entire SDN network. It plays a very important role in grasping the resource view of the entire network and improving the quality of network resource delivery. [0003] Existing SDN controllers store control logic and data (such as configuration information, control rules, routing information, etc.) together, that is to say, each SDN controller has its own independent data storage. It is very convenient when only a few SDN controllers need to be configured in a network. You only need to configure these SDN controllers into a cluster, and the data of each SDN controller will be copied to each other to ensure its high availability. But when a large-sca...
