Link fault reporting method and processing method, and transmission node and primary node

Abstract

The embodiment of the invention provides a link fault reporting method and a processing method, and a transmission node and a primary node. The reporting method comprises that: the transmission node on a looped network monitors a primary port of the transmission node so as to wait for receiving a message; if the transmission node does not receive any message on the primary port within a preset receiving period of time, a first link fault message is sent to the primary node on the looped network from a secondary port which is matched with the primary port so that the primary node judges that a link fault occurs in the looped network according to the first link fault message, wherein the receiving period of time is less than a transmission period of time of an entire link of the looped network. The situation that the link fault occurs in the looped network can be judged by the technical scheme under the condition that the primary node does not need to wait until time of a Fail timer of the primary node is out so that time for detecting that the link fault occurs in the looped network by the primary node is reduced.

Description

technical field [0001] The invention relates to communication technology, in particular to a link failure reporting method, processing method, transmission node and master node. Background technique [0002] Rapid Ring Protection Protocol (RRPP for short) is a link layer protocol specially applied to Ethernet rings. It can prevent the broadcast storm caused by the data ring when the Ethernet ring is complete, and can quickly activate the backup link to restore the communication path between the nodes on the ring network when a link on the Ethernet ring is disconnected. [0003] The master node on the ring network actively detects the health status of the ring network through the ring network active detection mechanism (Polling mechanism). If the HELLO message sent by itself can be received from its secondary port before the Fail timer expires, it means that the ring network link is complete; otherwise, the ring network is considered to have a link failure. The timing durat...

Problems solved by technology

[0004] However, when a port is down due to a physical port failure, service board hardware failure, or an optical transceiver abnormality, the transit node may not be able to detect it, so it will not actively send a LINK-DOWN packet to the master node. The master node only A link failure in the ring network can only be determined after the Fail timer expires, and the fault detection time is too long
