Patent ID: 8917601

Claim:
A method of managing data across IB networks, the method comprising: multicasting a first ARP request from a source node, the first ARP request including an IP address of a source port of the source node; performing load-balancing of host traffic across a plurality of ports of a plurality of nodes by sending a reply from a destination node corresponding to the IP address included in the first ARP request, the reply being sent over the source port to the source node; and selecting the source port of the source node to which to respond, based on an IP over IB GUID of the destination node, wherein the selecting includes: identifying a corresponding IP address of a destination node to the IP address of the source node, determining in a first level of an ARP cache a corresponding IP over IB GUID of the destination node to the IP address of the destination node, and locating a corresponding IB address to the IP over IB GUID of the destination node in a second level of the ARP cache.
