Problems solved by technology

[0008] For an RRPP network with subrings, if the primary ring has a multi-point failure, or the auxiliary edge node does not receive the subring Edge-Hello packet, to prevent broadcast loops, the edge port of the edge In this case, the edge nodes will block all the edge ports, which will cause the nodes on the sub-ring to be isolated, unable to forward packets, and unable to communicate with services on the main ring

Embodiment 1

[0030] This embodiment provides a method for edge port blocking in an Ethernet ring network. The Ethernet ring network includes a main ring and a sub-ring. The main ring and the sub-ring intersect at two nodes. One of the two nodes is an edge node, and the other To assist edge nodes, the method includes:

[0031] 1) After the edge node receives the Major-Fault message (main ring failure notification message) sent by the auxiliary edge node, it checks the number of edge ports;

[0032] 2) When the number of edge ports is one, the edge port is not blocked;

[0033] 3) When there are multiple edge ports, select one edge port from the plurality of edge ports without blocking, and block the unselected edge ports.

[0034] Among them, the above-mentioned edge nodes will periodically send Edge-Hello packets to the auxiliary edge nodes. When the auxiliary edge nodes do not receive the Edge-Hello packets within the preset time, they will consider the main ring link to be faulty. Send...

Embodiment 2

[0053] Referring to Figure 6, this embodiment provides an Ethernet ring network system, the Ethernet ring network includes a main ring and a sub-ring, the main ring and the sub-ring intersect at two nodes, one of the two nodes is an edge node, and the other is a Auxiliary edge nodes, where,

[0054] The edge node is used to send the main ring integrity check message to the auxiliary edge node. After receiving the main ring failure notification message sent by the auxiliary edge node, check the number of edge ports. The edge port is only connected to the sub-ring port; when the number of edge ports is one, the edge port is not blocked; when the number of edge ports is multiple, select an edge port from multiple edge ports without blocking, and block the unselected edge port;

[0055] The auxiliary edge node is used to judge whether the main ring integrity check message sent by the edge node is received within a preset time, and if not, send a main ring failure notification mess...

Embodiment 3

[0065] Referring to FIG. 7, this embodiment provides a device, which is an edge node where the main ring and the sub-ring intersect in the Ethernet ring network, including:

[0066] The main ring failure detection module is used to confirm that the main ring fails after receiving the main ring failure notification message sent by the auxiliary edge node;

[0067] The edge port blocking module is used to check the number of edge ports after the main ring failure detection module confirms the main ring failure, wherein, the edge port is a port that only connects to the sub-ring; when the number of edge ports is one, no blocking The edge port; when there are multiple edge ports, select one edge port from the plurality of edge ports to not block, and block the unselected edge port.

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 ...
