Method for obtaining network address and FCoE target and communication system

Abstract

The embodiment of the invention provides a method for obtaining a network address and a fiber channel over Ethernet (FCoE) target and a communication system. The method comprises the following steps that: according to a network registration request sent by an FCoE initiator, whether the FCoE initiator has a network address in an FCoE network is determined; if not, the network registration request is forwarded to an FCoE forward (FCF); And a network registration request response message from the FCF is received, and the response message is returned to the FCoE initiator that sends the network registration request, wherein the network registration request response message includes the network address in the FCoE network of the FCoE initiator. Therefore, the FCoE initiator can successively obtain the network address in the FCoE network on condition that the present FCoE initiator and the present FCF are not changed, so that the investment of a client on the present FCoE initiator and the FCF is protected, and the network construction cost is also saved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for obtaining a network address, an Ethernet fiber channel protocol target device and a communication system. Background technique [0002] Fiber Channel over Ethernet (FCoE) is a new technology standard formulated by the American National Standards Institute, which can map Fiber Channel to Ethernet, so that Storage Area Network (Storage Area Network) can be transmitted on Ethernet , SAN) data. [0003] In the prior art, the FCoE initiator (FCoE Initiator) sends a broadcast to all FCF (FCoE forward, Fiber Channel over Ethernet protocol converter) broadcast addresses (ALL-FCF-MACs) defined in the standard to obtain the Ethernet fiber in the current network The Media Access Control (MAC) address of the channel protocol converter (FCoE forward, FCF), the FCoE initiator selects an FCF address from the obtained FCF MAC addresses to send the Flogi registration information, and the F...

Problems solved by technology

[0004] The inventor found in the process of implementing the present invention that when the FCoE initiator performs network registration in the FCoE network, the FCoE initiator selects any FCF to perform Flogi registration. The target obtains the N-Port ID, so it cannot obtain the network address in the FCoE network, so it cannot establish a communication connection with the network nodes in the FCoE network
