a method and device for local area network emulation over an infiniband fabric . an ib lan driver at a first node on an ib fabric receives the port and associated local identifier of one or more remote peer nodes on the ib fabric . an ieee 802 . 3 ethernet mac address with one lid imbedded is generated . the imbedded lid is for one or more remote peer nodes . the ib lan driver sends the ethernet mac address to an address resolution protocol . a logical address of a remote peer node is generated by a network protocol . the logical address is mapped to an ethernet mac address . the ib lan driver sends the ethernet mac address onto the ib fabric to the one or more remote peer nodes . the remote peer nodes appear to reside on an ethernet network to the network protocol .
