Abstract

The invention discloses an SDN management network architecture, which comprises an SDN controller, a core node layer 3 switch, openflow switches, branch node layer 3 switches, a VPN server and internet access equipment, wherein the SDN controller is deployed at a core node of a network; the SDN controller is connected to the core node layer 3 switch; the branch node layer 3 switches and the openflow switches are deployed at branch nodes; a management port and a service port of each openflow switch are respectively connected to two ports of the corresponding branch node layer 3 switch; the VPNserver is deployed at the core node and is connected to internet through the internet access equipment; in-band management channels are established between the core node and the branch nodes based onan SDN service network, and the in-band management channels are virtual leased lines established by configuring an initialization flow table of the openflow switches; and VPN leased lines are established between the core node and the branch nodes through the internet and are taken as out-of-band escape management channels which have lower levels of usage than the in-band management channels.

Description

technical field

[0001] The 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 schemes: a...
