Equipment switching method, device and system based on fiber communication network

Abstract

The invention discloses an equipment switching method, device and system based on a fiber communication network, which is used for solving the problems of low information interaction efficiency between a host end and a data center network and loss of transmitted information possibly caused by the equipment switching mode in the prior art. The method comprises the steps as follows: based on the first state information of current multiple detection objects and the second state information of the multiple detection objects in the normal state, an FCoE (Fiber Communication over Ethernet) exchanger judges whether a path from itself to the data center network fails; and if so the host end is notified to be switched to other FCoE exchangers. As the FCoE exchanger detects whether a path from itself to the data center network fails and notifies the host end to perform equipment switching in case of failure, the host end can be switched to other FCoE exchangers in time so as to perform information interaction with the data center network, thereby improving the information interaction efficiency between the host end and the data center network and avoiding the loss of transmitted information.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a device switching method, device and system based on an optical fiber communication network. Background technique [0002] In an optical fiber communication network based on Fiber Channel over Ethernet (FCoE) technology, the host end performs information exchange with the data center network through the connected FCoE switch, where the FCoE switch is used to communicate between the host end and the data center network. Forward data. [0003] In order to improve the reliability of information exchange between the host end and the data center network, the host end is usually connected to at least two FCoE switches, and performs information exchange with the data center network through the FCoE switch with the highest priority among the at least two FCoE switches. When the host side detects that the FCoE switch with the highest priority fails, or the line between th...
