A network intercommunication method, applied to a gateway device. The gateway device comprises a VN2VN_Port and an F_Port; the gateway device accesses a lossless Ethernet network via the VN2VN_Port, and is connected to an FC device having an N_Port via the F_Port; the gateway device receives an FLOGI message sent by the FC device, and configures identification information for the FC device according to the FLOGI message, the identification information comprising a WWPN, an N_Port ID and an MAC address; a Probe Request containing the identification information is sent to an FCoE device in the lossless Ethernet network in a multicast manner; when a Probe Reply sent by each FCoE device in the FCoE devices is received, and according to the Probe Reply sent by each FCoE device, it is determined that the identification information configured for the FC device does not conflict with identification information about any FCoE device in the lossless Ethernet network, and a corresponding relationship between the FC device and the identification information is stored; and an FLOGI Accept message is sent to the FC device, the FLOGI Accept message carrying the identification information. The present invention achieves intercommunication between an FCoE device with a VN-Port and an FC device with an N-Port with relatively low costs.
Description
Technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a method and device for network intercommunication. Background technique [0002] Fibre Channel Storage Area Network (English: Fibre Channel Storage Area Network, abbreviation: FC-SAN) is generally composed of N port (English: N_Port) equipment and Fibre Channel network (English: FC Fabric), where N-Port equipment can be configured with The FC device of a host bus adapter (English: Host Bus Adapter, abbreviation: HBA), the FC device may be a host or a storage device. The N-Port device needs to register with the FC Fabric during initialization, and the FC Fabric allocates an N-port identifier (English: N_Port_ID) to the N-Port device, which is used to identify the N-Port device in a subsequent communication process. [0003] Virtual N Port-Virtual N Port (English: Virtual N_Port to Virtual N_Port, abbreviation: VN2VN_Port) network is a new type of ne...
