SDN ARCHITECTURE, SDN ARCHITECTURE-BASED MESSAGE FORWARDING METHOD

摘要

An SDN architecture and a method for forwarding message based on the SDN architecture are provided. The SDN architecture includes controllers and a forwarding device, and the SDN further includes: a monitoring controller, which is connected between the multiple controllers and the forwarding device and configured to receive or monitor control plane messages of the multiple controllers, and determine a flow table to be sent to the forwarding device according to a local strategy and the control plane messages of the multiple controllers. By adopting the technical solutions provided by the present disclosure, the technical problems of message forwarding behavior disorder caused by lack of a communication standard between the multiple controllers and incapability in unified coordination of decisions of the multiple controllers for the forwarding device and the like in the related technology are solved, so that reliability of a network and message forwarding accuracy are improved.
