A link management method, board and switch

Abstract

The present application provides a link management method, a board and a switch, the method is applied to the link management process deployed in the switch, the switch is deployed in the Ethernet ring network and is connected to the main service link in the Ethernet ring network respectively and the standby service link connection, the link management process only processes related services related to the failure of the main service link, and the method includes: if it is determined that the main service link is faulty, enabling the backup service link. By deploying the link management process in the switch that only handles the related services related to the failure of the main service link, once the main service link fails, the link management process can detect and process the fault message at the first time, so as to enable low-latency Backup service links to ensure service stability.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a link management method, a board card, and a switch. Background technique [0002] ERPS (Ethernet Ring Protection Switching, Ethernet Ring Protection Switching) is a two-layer ring breaking protocol standard defined by ITU-TG.8032. The G.8032 protocol realizes the protection of the Ethernet ring network. In the Ethernet ring network based on G.8032, it usually includes a main service link and an RPL (Ring Protection Link, ring protection link) link. The RPL The link is usually used as a backup service link. Normally, the primary service link is enabled, but the backup service link is not enabled. Once the primary service link fails, the switches in the Ethernet ring network perform link switching to enable the backup service link. [0003] However, because the core process of the switch is not only responsible for the link switching of the process, it ...

Problems solved by technology

[0003] However, since the core process of the switch is not only responsible for the link switching of the process, it is also responsible for processing other services related to the Ethernet ring network, so the fault cannot be detected and processed by the core process at the first time, resulting in a relatively long delay in link switching long, affecting business stability
