Abstract

This application provides a method and system for collaborative management of multiple control domains in an SDN network. When a cross-domain request occurs in a single-domain controller, the cross-domain request is integrated and encapsulated with the content of the request that needs to be involved in global decision-making, and the package is obtained The optimization request is sent to the multi-domain cooperative controller, and the multi-domain cooperative controller calculates the complete path information required for the cross-domain request according to the optimization request, and feeds back the information to the single domain controller. The flexibility of message processing of the controller is improved, and the utilization efficiency of the network is improved.

Description

technical field [0001] The present invention relates to the technical field of software-defined networks, in particular to a method and system for collaborative management of multiple control domains of an SDN network oriented to wide-area interconnection. Background technique [0002] With the wide application of new technologies such as big data, cloud computing, Internet of Things and mobile Internet in the power industry, new requirements and challenges have been put forward for the construction of power backbone transmission networks. During the construction of the power backbone transmission network, not only data centers are deployed on the backbone network to provide business support, but also provincial and municipal levels have gradually deployed their own data centers. Due to regional network management and vendor competitiveness, multi-vendor, multi- Scenarios for domain networking and wide-area interconnection exist. Although the Software Defined Network (SDN, ...
