Embodiment Construction

[0020] Functional Overview

[0021] In an embodiment of the present invention, a link fault detection solution is provided. In this implementation solution, the forked node includes a first port, preferably, also includes a second port, and the first port is connected to the first link. The first link is in the forwarding state, the first port is in the connected state, and when the first port switches from the connected state to the disconnected state, the fork node determines that the first link has failed.

[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

Abstract

The invention discloses link fault detection method and system, applied to an Ethernet double-return connection system which comprises double-return bifurcated bridge nodes and double-return links. In the link fault detection method, a protection group is set for each double-return bifurcated bridge node, wherein the protection group comprises the master port and the slave port of the double-return bifurcated bridge node; and for each protection group, when one port of the protection group is detected to be switched to an off state from a connection state, the double-return link connected with the port is judged to go wrong. According to the technical scheme of the invention, the problem of poor reliability and real-time property of link fault notification can be solved and high-efficiency link fault detection can be realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a link fault detection method and system. Background technique [0002] The Ethernet widely adopts the networking structure of the Ethernet dual-homing connection network, that is, an Ethernet connection network in which an Ethernet area is connected to another area through a primary link and a backup link. Under normal circumstances, data passes through the active link. When the active link fails, the traffic is switched to the standby link, so as to realize the redundant backup of the link functionally and improve the reliability of the network. [0003] Among the services of the Ethernet network, some services have higher and higher requirements on the reliability and real-time performance of the network, and sometimes there are many nodes on the dual-homing link. Therefore, it is necessary to protect the Ethernet dual-homing connection with high reliability, and quickly per...
