Embodiment Construction

[0044] Aiming at the problems existing in the prior art, an embodiment of the present invention provides a method for processing multi-point faults of an EPRS ring, which can be applied to an ERPS network including a main ring and multiple sub-rings.

[0045] In the embodiment of the present invention, for two interconnected nodes on a sub-ring: (1) Common (public) ports are respectively configured on the two interconnected nodes, and the Common port is a port on the public link of the main ring and the sub-ring . In addition, non-common ports and sub-ring ports are also included on interconnection nodes. The non-common ports refer to the ports other than the common ports on the main ring of interconnection nodes. The sub-ring ports refer to the ports other than the common ports on the same sub-ring as the common ports on the interconnected nodes. (2) Interconnection MAC (Media Access Control, Media Access Control) addresses are respectively configured on the two interconnec...

Abstract

The invention discloses a processing method and device for a multi-point fault of an EPRS loop circuit. The method includes the following steps: when a fault happens in a link of a Common port of a first interconnection node, the first interconnection node determines whether a multi-point fault happens in a main ring which the first interconnection node is in; and if the first interconnection node determines that the multi-point fault happens in the main ring, a first priority of triggering of a first MS event by the first interconnection node is determined; and the first interconnection node blocks a first subring port of the first interconnection node and sends a first MS message through the first subring port, wherein the first MS message carries the first priority. In the processing method and device for the multi-point fault of the ERPS loop circuit is capable of preventing problems of traffic interrupt and the like.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and equipment for processing multi-point faults of an EPRS loop. Background technique [0002] ERPS (Ethernet Ring Protection Switching, Ethernet Ring Protection Switching) is a link layer protocol specially applied to Ethernet rings. When the Ethernet ring is complete, ERPS can prevent broadcast storms caused by data loops. When a link on the Ethernet ring is disconnected, ERPS can quickly restore the communication path between each node (that is, network device) on the Ethernet ring, and has a high convergence speed. [0003] Such as figure 1 As shown in FIG. 2 , it is a schematic diagram of networking of a multi-ring ERPS network, and the ERPS network includes a main ring and two sub-rings. Among them, the main ring includes node A, node B, node C and node D, node A is the master node, node B is the neighbor node, node C and node D are common nodes, and the l...
