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 a method and device for intercommunication between SDN and non-SDN. The method includes: determining each edge network device of SDN and the edge port of each edge network device; The port identification of the edge port, so that each edge network device receives the protocol packet recorded in the report on the protocol packet, and then reports the protocol packet and the port identification of the edge port; after receiving the protocol packet and the port identification of the edge port , and send an opening notification to the edge network device that reports the protocol message, so that the edge network device that reports the protocol message enables the protocol corresponding to the protocol message on the edge port that receives the protocol message and uses the port address to communicate with the non-SDN The network device of the protocol message learns and reports the routing table items; obtains the routing table of the entire network according to the received routing table items and sends it to each network device of the SDN. This solution will not cause SDN route flapping, thereby greatly improving 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...
