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

Embodiment Construction

[0035] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0036] see figure 1 and figure 2 , the embodiment of the present application provides a link management method, the link management method can be applied to a switch, the link management process of the switch running on the forwarding plane is responsible for link failure processing, in other words, the method can be managed by a link Process execution, the switch is deployed in the Ethernet ring network, the Ethernet ring network can include the main service link and the backup service link, and the link management process only handles the related services of the main service link failure.

[0037] If the switch is respectively connected to the main service link and the backup service link in the Ethernet ring network, the link management method may include: if the link management pr...

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 ...
