Abstract

The invention belongs to the technical field of the communication, and specifically discloses a SDN controller cluster and a network system. The SDN controller cluster comprises a SDN controller group, and a cache server group for correspondingly storing control data of the SDN controller group according to a search rule configured in the SDN controller group, wherein the control data at least comprises configuration information, a control rule, routing information and topological data. Through the SDN controller cluster and network system provided by the invention, the control logic and the data storage of the SDN controller are separably stored, namely.e., the data storage is placed on a distributed cache system in a unified way, each SDN controller only has the control logic and has nodata storage, the redundancy of the data is not increased when the large-scale SDN controller cluster is required; and different SDN control data can be stored on different cache systems so as to realize the lateral extension of the data storage.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an 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-scale SDN contr...
