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 r...

Abstract

The invention provides topology discovery method and equipment of a resilient packet ring (RPR) in an SDN. By means of the topology discovery method and equipment, the topology discovery of the RPR can be achieved in the SDN; besides, different from the topology discovery of an existing RPR, the mode that the TP frame, the ATD frame and the TC frame are adopted for all network equipment in the topology discovery of the existing RPR to spread the topology information is eliminated, the protocol level functions of the existing RPR are uniformly integrated to an SDN controller, and the network topology information is collected by the SDN controller in a concentrated mode.

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...
