Embodiment Construction

[0054] Aiming at the problems existing in the prior art that cause SDN route oscillations and seriously affect user experience, the embodiment of the present invention provides a method for intercommunication between SDN and non-SDN, which is applied in the controller of SDN, and the process is as follows: figure 2 As shown, the specific execution steps are as follows:

[0055] S21: Determine each edge network device of the SDN and an edge port connecting each edge network device to a non-SDN network device.

[0056] Such as figure 1 As shown, SDN and non-SDN are connected to each other, and the network equipment connected with non-SDN network equipment in SDN can be defined as the edge network equipment of SDN, and the number of edge network equipment can be one or more; and the edge network A port connected to a non-SDN network device in the device may be defined as an edge port of an edge network device, and each edge network device may have one or more edge ports.

Abstract

The invention discloses an intercommunication method and apparatus of an SDN and a non-SDN. The method comprises the following steps: determining edge network devices of the SDN and edge ports of theedge network devices; issuing protocol message reporting tables and port identifiers of the corresponding edge ports to the edge network devices, so that the edge network devices report protocol messages and the port identifiers of the edge ports when receiving the protocol messages recorded in the protocol message reporting tables; after the protocol messages and the port identifiers of the edgeports are received, issuing an opening notification to the edge network devices reporting the protocol messages, so that the edge network devices reporting the protocol messages open protocols corresponding to the protocol messages on the edge ports that receive the protocol messages, performs routing table entry learning with the network devices that send the protocol messages in the non-SDN by using port addresses, and reports routing table entries; and obtaining a whole network routing table according to the received routing table entries, and issuing the whole network routing table to thenetwork devices of the SDN. By adoption of the scheme, no routing oscillation of the SDN is caused, thereby greatly improving the user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for interworking between a Software Defined Network (SDN) and a non-SDN. Background technique [0002] SDN is a new type of network architecture in the Emulex network and a way to realize network virtualization. SDN network devices need to support the SDN control mode before they can be controlled by the SDN controller. Therefore, the existing SDN is basically a newly constructed network, and the old network devices basically do not support providing interfaces for the SDN controller to customize the network. Therefore, how to integrate SDN and old non-SDN to make network deployment more flexible has always been a big problem. [0003] Such as figure 1 In the network architecture shown, there are three non-SDN: Internet-1, Internet-2 and Internet-3, Internet-1 is connected to SDN through non-SDN network device 1, Internet-2 is connected to SD...
