Abstract

The invention discloses a method for blocking edge port in Ethernet ring network, Ethernet ring network system and equipment, belonging to the communication field. The method comprises: after receiving the main ring fault notice message transmitted by an auxiliary edge node, an edge node checks the number of the edge port; unblocking the edge port when the edge port has a number of one; selecting one edge port from multiple edge ports unblocked and blocking unselected edge port when the edge port has more than one; the edge node and auxiliary edge node of the system. The equipment comprises a main ring fault detection module and an edge port block module. When the main ring has multi-point fault, one edge port is unblocked and other edge ports are blocked, thereby ensuring the normal transmission of business flow and preventing broadcasting ring circuit.

Description

technical field

[0001] The invention relates to the communication field, in particular to a method for blocking an edge port in an Ethernet ring network, an Ethernet ring network system and equipment. Background technique

[0002] RRPP (Rapid Ring Protection Protocol) is a link layer protocol specially applied to the Ethernet ring network. It can prevent broadcast storms caused by data loops in the Ethernet ring network. When a link on the Ethernet ring network When disconnected, the backup link can be activated quickly to restore the communication link between the nodes on the ring network.

[0003] In the RRPP protocol, the RRPP intersecting ring networking mode is supported. Refer to the RRPP networking schematic diagram provided in Figure 1, in which the ring composed of nodes 1, 2, 3, and 4 is the main ring, and nodes 3, 4, and The ring formed by 5 and node 6 is a sub-ring; both the main ring and the sub-ring have master nodes, which are respectively node 1 and node 5 ...
