Load balancing method, device and system

Abstract

The invention provides a load balancing method, device and system. The method comprises the following steps of: when an equipment finding request message sent by an FCoE (Fiber Channel over Ethernet) terminal is received, acquiring the forwarding priority of each piece of FCF (Fiber Channel Forwarder) equipment corresponding to the FCoE terminal respectively according to FCF information collected from each piece of FCF equipment in the same network; and sending an equipment finding answering message to the FCoE terminal, wherein the equipment finding request message carries the forwarding priority, so that the FCoE terminal can be used for forwarding a message by selecting FCF equipment with the highest forwarding priority according to the forwarding priority of each piece of FCF equipment corresponding to the FCoE terminal. The invention further provides a load balancing method, the FCF equipment, the FCoE terminal and a load balancing system. According to the invention, load balance of the FCF equipment is realized, and excessively high load and flow of the FCF equipment with a high forwarding priority are avoided.

Description

technical field [0001] The present invention relates to communication technology, in particular to a load balancing method, device and system. Background technique [0002] Storage Area Network (hereinafter referred to as: SAN) is a fast and dedicated network that connects different storage devices to servers. figure 1 It is a schematic diagram of a typical architecture of a SAN network in the prior art. Fiber Channel (Fibre Channel; hereinafter referred to as: FC) is the most mainstream supporting technology in the existing SAN, which itself defines a set of protocol stacks that follow the Open System Interconnect (hereinafter referred to as: OSI) model, through FC Relevant protocol standards realize mutual visits between SAN network servers and storage devices. Converged Enhanced Ethernet (Converged Enhanced Ethernet; hereinafter referred to as CEE) may include a data center bridge (Data Center Bridging; hereinafter referred to as DCB) and a data center Ethernet (Data Ce...

AI Technical Summary

Problems solved by technology

[0004] However, the existing technology will cause the load and traffic of the FCF device with high forwarding priority to be too large, while other FCF devices are in an idle state, and the load of the device will be unbalanced.
