Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] The method provided by the present invention can realize the topology discovery of RPR in SDN, and the topology discovery is different from the existing RPR topology discovery, specifically: the present invention cancels the use of TP frames, ATD frames and TC frames propagate topology information, and centralize the functions of the existing RPR protocol layer to the SDN controller, realizing the centralized collection of network topology information by the SDN controller.

[0056] pass below figure 2 The method provided by the invention is described:

[0057] see figure 2 , figure 2 The flow chart of the method provided by the present invention. In this method, for the convenience of description, the present invention collectively re...

Abstract

This application provides a topology discovery method and device for RPR in SDN. The present invention can realize the topology discovery of RPR in SDN, and, different from the topology discovery of the existing RPR, the present invention cancels the use of TP frames, ATD frames, and TC frames to propagate topology information by each network device in the existing RPR topology discovery, and will The functions of the existing RPR protocol layer are centralized on the SDN controller, which realizes the centralized collection of network topology information by the SDN controller.

Description

technical field [0001] The present application relates to network communication technology, in particular to a method and device for implementing a Resilient Packet Ring (RPR: Resilient Packet Ring) in a Software Defined Network (SDN: Software Defined Network). Background technique [0002] SDN is a new type of network architecture, which is used to extract the control plane of network equipment from scattered network equipment to form a centralized controller, which can work on the cloud server array, with the help of the powerful computing of the cloud server Ability to complete various tasks such as topology collection, service processing, and forwarding decision-making of the entire network. [0003] RPR is a new type of media access control (MAC: Media Access Control) protocol, which can run on optical synchronous network (SONET: Synchronous Optical Network) / synchronous digital system (SDH: Synchronous Digital Hierarchy), dense wavelength division multiplexing (DWDM ...
