Abstract

The invention discloses an SDN management network architecture, including: an SDN controller, a core node three-layer switch, an openflow switch, a branch node three-layer switch, a VPN server, and an Internet access device; the SDN controller is deployed at the core node of the network, The SDN controller is connected to the layer-3 switch of the core node; the layer-3 switch and the openflow switch of the branch node are deployed in the branch node, and the management port and a service port of the openflow switch are respectively connected to the two ports of the layer-3 switch of the branch node; the VPN server is deployed At the core node, connect to the Internet through the Internet access device; establish an in-band management channel based on the SDN service network between the core node and the branch node, and the in-band management channel is a virtual private line established by configuring the initialization flow table of the openflow switch; Between the node and the branch node, a VPN dedicated line is established through the Internet, which is called an out-of-band escape management channel, and its usage level is lower than that of the in-band management channel.

Description

technical field [0001] The present invention relates to network technology, in particular to an SDN management network architecture, a method for establishing an SDN management network, and a switching method for an SDN management network. Background technique [0002] SDN (Software Defined Networking) is an innovative network architecture compared to traditional networks. By separating the data plane and control plane of network devices, the data plane has flexible and programmable flow forwarding capabilities. The basic SDN network architecture consists of an SDN controller and an openflow switch. A management network needs to be built between the SDN controller and the openflow switch for intercommunication. The SDN controller is supported to deliver the flow table to the openflow switch and the openflow switch to report the status to the SDN controller, etc. information. [0003] Under the prior art, in common commercial deployment, there are mainly two implementation s...
