Patent ID: 7724748

Claim:
A method, including: at a local Infiniband (IB) node having an Infiniband local area network (IBLAN) driver in an IB subnet emulating an Ethernet network interface card (NIC) driver; the IB node receiving an outbound Ethernet frame wherein a destination Ethernet address in the outbound Ethernet frame corresponds to a remote Ethernet address extracted from a local address resolution protocol (ARP) table, and wherein the remote Ethernet address and a destination network address are associated in the local ARP table; embedding the outbound Ethernet frame in at least one outbound IB request packet to tunnel the outbound Ethernet frame across the IB subnet; and causing the at least one outbound IB request packet to be sent to at least one remote IB node on the IB subnet, wherein the at least one remote IB node is configured with a remote IBLAN driver; upon receiving the outbound Ethernet frame at the local IBLAN driver, extracting a destination IB local identifier (LID) embedded in the destination Ethernet address in the outbound Ethernet frame; and populating a destination IB LID field in a local route header associated with the at least one outbound IB request packet with the destination IB LID, wherein the destination IB LID corresponds to the at least one remote IB node.
