Problems solved by technology

It can be seen that the edge nodes and the main nodes of the sub-rings block and release more ports respectively, and the processing is more complicated, and the processing complexity increases with the number of sub-rings increasing
[0035] 2) Since the edge node corresponding to the sub-ring is blocked and both SRPT links fail, the edge node and the nodes connected to the edge node are blocked, and these nodes cannot communicate with other nodes, for example, image 3 Node F in the network cannot communicate with node B, resulting in these nodes being isolated and network node resources cannot be fully utilized

Embodiment Construction

[0091] The present invention improves the existing SRPT state detection and fault handling mechanism, uses a certain sub-ring link in the dual-homing network as the backup link of the SRPT link, and when the SRPT fails, the backup link is used as the backup link for other sub-rings. The ring transmits RRPP protocol packets, which can avoid the formation of loops between sub-rings, simplify the port operations of edge nodes and sub-ring master nodes, and improve the utilization of network node resources. The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0092] The embodiment of the present invention introduces the concept of a backup link. The backup link refers to the link on the sub-ring except the part that intersects with the main ring. by figure 2 For example, the remaining link of sub-ring 1 after removing the part of node B-node C: node B-node F-node C is the backup link of sub-ring 1. ...

Abstract

The invention provides a processing method and node equipment for a loop fault in a dual-homing network. When the SRPT link fails, the present invention can simplify the SRPT state detection and fault handling mechanism in the prior art by using a certain sub-ring to transmit RRPP protocol messages for other sub-rings, and reduce the number of isolated ring nodes and improve the Utilization of network node resources.

Description

technical field [0001] The present invention relates to the technical field of Rapid Ring Protection Protocol (RRPP, Rapid Ring Protection Protocol), in particular to a method for processing a ring failure in a dual-homing network and a node device. Background technique [0002] RRPP 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 restore the communication path between the nodes on the ring network when a link on the Ethernet ring is disconnected. The following briefly introduces related concepts in RRPP. [0003] RRPP ring: A ring-connected Ethernet network topology is called an RRPP ring. In this document, the RRPP ring is referred to as "ring" for short. RRPP rings are divided into major rings and subrings. An RRPP domain can contain multiple RRPP rings, but only one main ring, and the others are sub-rings. Each ring has the following two states...
