Embodiment Construction

[0032] figure 2 The flow chart of the FCoE communication method provided by the embodiment of the present invention; image 3 A network structure diagram applicable to the FCoE communication method provided by the embodiment of the present invention. The embodiment of the present invention aims at that when there is no FCF device in the communication network, any two FCoE devices in the Ethernet will be unable to communicate, which reduces the communication capability of the FCoE device, and provides an FCoE communication method. The specific steps of the method are as follows:

[0033] Step S101, the source FCoE device generates a source FC address according to the source WWN number uniquely corresponding to the source FCoE device;

[0034] Such as image 3 There is no FCF device in the shown network structure diagram. In the embodiment of the present invention, it is reasonable to assume that the source FCoE device is image 3 In FCoE device 1, the destination FCoE devic...

Abstract

Embodiments of the present invention provide an FCoE communication method, device and system. The method includes: the source FCoE device generates a source FC address according to the source WWN number uniquely corresponding to the source FCoE device; if the source FC address does not conflict with the FC addresses of other FCoE devices, broadcast address request information; The FC address, the destination FC address and the destination MAC address generate communication request information, and send the communication request information to the destination FCoE device. In the embodiment of the present invention, the source FCoE device generates the source FC address according to the source WWN number, obtains the destination FC address and destination MAC address corresponding to the destination FCoE device through broadcast address request information, and sends communication request information to the destination FCoE device. When there is no FCF device, it is guaranteed that any two FCoE devices in the Ethernet can communicate, and the communication capability of the FCoE device is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an FCoE communication method, device, and system. Background technique [0002] The Fiber Channel over Ethernet (FCoE) technical standard can map Fiber Channel to Ethernet, and insert Fiber Channel information into Ethernet packets, so that Fiber Channel requests and exchanges between servers and storage devices Data travels over Ethernet without the need for a dedicated Fiber Channel fabric. [0003] Such as figure 1 As shown, FCoE device 1 in the prior art is connected to FCF device 1 through Ethernet, FCoE device 2 is connected to FCF device 2 through Ethernet, FCF device 1 is connected to FC network 1 at the same time, FCF device 2 is connected to FC network 2 at the same time, and FC network 1 includes FC node 1, and FC network 2 includes FC node 2, that is, FCoE device 1 in Ethernet can communicate with FC node 1 in FC network 1 through...
