Abstract

The invention provides an SDN (Software Defined Network)-based path calculation method and device under multi-dimensional constraints, and the method comprises the steps: receiving a path calculationrequest of a service, and enabling a plurality of service scenes of the service to be available; wherein the path calculation request comprises a constraint type corresponding to the service and an evaluation type corresponding to the service; matching the constraint type with a preset multi-dimensional constraint model to obtain a multi-dimensional constraint set corresponding to the service; matching the evaluation type with a preset evaluation model to obtain an evaluation function corresponding to the service; and carrying out path calculation according to a multi-dimensional constraint set and an evaluation function. The problems that in the prior art, a service module of an SDN controller is coupled with a path calculation module, an SDN controller is low in operation efficiency dueto the fact that a path calculation module cannot serve as an independent component to be used for other business scenes and path calculation performance is bottleneck due to the fact that constraintsused in the path calculation process are fixed are solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for calculating a path under multi-dimensional constraints based on an SDN network. Background technique [0002] Software Defined Network (SDN for short) is a new type of network structure, in which the SDN controller is the middle layer in the three-layer architecture, which plays a key role in linking the past and the future, and the core of the controller is the control plane and the forwarding plane Separation, the control plane completely controls the forwarding behavior, making the device completely a white box. The business application layer is the top layer of the SDN network, and it is some applications that use controllers to implement security, management and other special functions. Therefore, the application layer is the direction controlled by the SDN controller. [0003] The asset library is used to store resource information, such as nodes...
