Ring network link failure processing method, device and ring network

Abstract

The embodiment of the invention provides a ring network link failure processing method, a ring network link failure processing device and a ring network. The ring network link failure processing method comprises the following steps of: detecting whether a link in the ring network fails or not; after the link is detected to fail, deleting the media access control information of a new blocked port; and transmitting a topological variation message to an adjacent node in the ring network by using a healthy port, wherein the topological variation message carries the information of the new blocked port. The embodiment of the invention also provides the corresponding device and the ring network. In the technical scheme provided by the invention, when the link fails, the number of ports deleting the medium access control (MAC) information can be reduced, the processing time and traffic convergence time of equipment can be shortened, simultaneously broadcasting traffic in the equipment is reduced and switching performance is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of network technologies, and in particular, to a method and device for processing loop network link faults, and a loop network. Background technique [0002] In the field of ring protocols, with the emergence of carrier-grade Ethernet, Ethernet has now become a carrier-grade network standard. The easiest way to enhance the function of Ethernet is to adopt the ring network technology with high reliability. At present, the Ethernet ring network control protocols in the industry include: Resilience Ethernet Protocol (Resilience Ethernet Protocol, hereinafter referred to as: REP), Rapid Ring Protection Protocol (hereinafter referred to as: RRPP), Smart Ethernet Protocol (Smart Ethernet Protocol) , hereinafter referred to as: SEP) and so on. [0003] Taking the SEP protocol as an example, each port in each network segment in the ring network has its own link state attribute (Link State Attribute...

Problems solved by technology

[0005] It can be seen that in the prior art, when a link failure occurs, the MAC information of each port connected to the loop network on the node needs to be deleted, and the processing time required for deleting the MAC information is relatively long. Therefore, the prior art The processing scheme for link failure in the middle increases the processing time of the device and the convergence time of the traffic.

And in the subsequent process of each node learning and generating MAC information, the broadcast traffic will also increase significantly, which will degrade the performance of the loop network
