Method, apparatus, name server and system for establishing FCOE communication connection

摘要

Embodiments of the present invention disclose a method, an apparatus, and a system for establishing an FCoE communication connection and a name server. According to a WWN world wide name identifier of a target to be accessed, a destination MAC address used to access the target to be accessed is acquired. According to the destination MAC address, a login operation is performed for the target to be accessed, to establish an FCoE fiber channel over Ethernet communication connection, so that an FCoE initiator may directly establish a communication connection with an FCoE target, thereby reducing data transmission delay and lightening the processing load of an original FCoE forwarder.

1. A method, executed in a lossless Ethernet by a Fiber Channel over Ethernet (FCoE) initiator configured to initiate a data access operation of a first target device, for establishing an FCoE connection between the first target device and the FCoE initiator, the method comprising:
sending, to one or more FCoE forwarders and one or more target devices in the lossless Ethernet, discovery solicitation messages for acquiring Media Access Control (MAC) addresses of the FCoE forwarders and the target devices; receiving, from one or more of the FCoE forwarders and one or more of the target devices, discovery advertisement messages in response to the discovery solicitation messages, wherein one of the discovery advertisement messages sent from the first target device includes a first MAC address of the first target device; sending, to a name server, a message including a World Wide Name (WWN) identifier of the first target device for acquiring identifier information of the first target device; receiving, from the name server, an answer message carrying the identifier information of the first target device; determining that the identifier information matches with at least a portion of the first MAC address of the first target device; and performing, a login operation to establish the FCoE connection with the first target device according to the first MAC address.
