Abstract

The invention relates to a method and system for determining an optimal path in SDN (Software Defined Network). The SDN comprises an SDN controller, an access equipment and an SDN switch. A link is detected by the SDN controller, the access equipment and the SDN switch, so as to determine the optimal path of the service in the SDN. The SDN controller comprises an SDN communication module, an SDN communication extension module, a detection module, a topology module, a service module, a service path computing module and other extensible service modules; the SDN switch comprises a standard SDN switch function module, an SDN communication extension module and a detection module; the access equipment includes a detection module. By adoption of the invention, various kinds of scenes can be adapted; and aiming at different scenes, one optimal path can be selected from a plurality of presetting optimal path algorithms.

Description

technical field [0001] The present invention specifically relates to a method and system for determining an optimal path in an SDN network. Background technique [0002] Software Defined Network (Software Defined Network, SDN) is a revolutionary change, which solves some problems that cannot be avoided in traditional networks, including lack of flexibility, slow response to changes in requirements, inability to realize network virtualization and high cost etc. SDN separates the control plane from the data plane in network switches and routers. The SDN controller implements functions such as network topology collection, routing calculation, flow table generation and distribution, and network management and control. [0003] Therefore, the role of routers in our future inter-data center network will change, from the original two functions of computing paths and forwarding messages to only the ability to forward messages, and the computing paths will be handed over to centrali...
