Patent ID: 8743878

Claim:
A method for path resolving in a symmetric InfiniBand network comprising a plurality of nodes, the method comprising: receiving, by a first node, a predetermined subnet prefix for each element in the symmetric InfiniBand network; transmitting, from the first node, a Management Datagram (MAD) to a second node, the MAD including a query for a Global Unique Identifier (GUID) for a port in the second node, the GUID comprising an assigned identifier for the port; receiving, by the first node, the GUID for the port in response to the MAD, wherein the predetermined subnet prefix and the GUID are received by the first node separate from each other; determining a Global Identifier (GID) for the port via concatenating the received GUID and the predetermined subnet prefix; querying a local port in the first node for each of a partition key (PKEY) for the local port, a GID for the local port, a Maximum Transit Unit (MTU) for the local port, and a data rate for the local port; and receiving the PKEY, the GID for the local port, the MTU for the local port, and the data rate for the local port in response to the query, wherein transmitting the MAD comprises transmitting the MAD utilizing a Source Local Identifier (SLID) in the first node to a Destination Local Identifier (DLID) in the port.
