Embodiment Construction

[0026] The core idea of ​​the present invention is: through ACL, forwarding entry, or flooding, broadcasting or multicasting in a VLAN, the fault message is transmitted to the master node through the protocol message, which does not need to occupy additional VLAN resources of the system, and improves the reliability of the system. Resource utilization; the ring topology of the present invention can realize failover within 50 milliseconds.

[0027] refer to figure 1 , is a schematic diagram of the Fast Ethernet ring network protection domain of the present invention, and relates to steps s1 and s2 of the Fast Ethernet ring network protection method of the present invention.

[0028] In step s1, an Ethernet automatic protection ring is created, and the automatic protection ring includes a master node. Nodes can be switches or routers, with two ports on each switch connected to ports on other switches, and so on, until a ring is formed.

[0029] In step s2, the master node sets...

Abstract

This invention discloses a kind of fast looped network protection method. It concludes: the fast looped network protection area is set up. Nodes are connected with each other through ports to form a loop. Each node is consisted with two ports that are connected with loop; master node sets the first port to retransmission mode and sets the second port to blocking mode; the link trouble is acquired through accessing control table, retransmission table entry or virtual local area network. The said virtual local area network retransmits data messages and protocol messages; when acquiring the link trouble, master node sets the second node to retransmission mode. The retransmission tables of master node and other nodes are refreshed. A special control VLAN aiming at protocol message does not need. Thus, it can save VLAN ID resource of each node.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a fast ring network protection method and system. Background technique [0002] With the gradual popularization and application of the Ethernet ring network, users have higher and higher requirements on the reliability of the Ethernet ring network. In the current application of the Ethernet ring network, the performance provided by the Spanning Tree Protocol (STP (Spanning Tree Protocol) family) can no longer meet the requirements of the Ethernet ring network. STP (Spanning Tree Protocol) can provide path redundancy. Using STP can make only one effective path between two terminals. STP defines a tree in a large network and forces certain backup paths to be in standby. If part of the network in the spanning tree is unreachable, or the STP path cost value changes, the spanning tree algorithm will recalculate the spanning tree topology and re-establish the connection by ...
