Abstract:
System and method for supporting intra- and inter-subnet address resolution in a network environment using the same linear forwarding tale (LFT) for both the intra- and inter-subnet forwarding. Subnet prefix values in global route headers (GRHs) are used for linear forwarding table (LFT) lookup in a high performance computing environments. An exemplary can provide for use of an Inter Subnet Route Number (ISRN) embedded in the subnet prefix values in the GRHs for LFT lookup in a network switch environment in a high performance computing environment such as a network having an InfiniBand (IB) architecture. A method can provide, at a computer environment, including a network fabric, one or more subnets, each of which subnets are associated with one or more network switches or hosts. The system and method is compatible with legacy switches and nodes that are not conversant with the ISRNs.

Claim (Index 1):
A method for using packet headers for linear forwarding table lookup in a network switch environment in a high performance computing environment, the method comprising:\n providing, at a computer environment including a network fabric, first and second subnets, the first subnet being different than the second subnet, the first subnet comprising a first set of network switches, a first linear forwarding table (LFT), and a first plurality of physical ports, and the second subnet comprising a second set of network switches, a second LFT, and a second plurality of physical ports; and allowing the first LFT of the first set of network switches to be used for both intra-subnet forwarding decisions of packets to be forwarded between ones of the first set of network switches of the first subnet and inter-subnet forwarding decisions of the packets to be forwarded between the first and second sets of network switches of the first and second subnets respectively by:\n receiving a first packet at a first network switch of the first set of network switches of the first subnet; \n inspecting a local route header (LRH) of the first packet; \n determining a condition of the LRH of the first packet; and\n making the inter-subnet forwarding decision based on the first LFT indexing, using a selected portion of the LRH of the first packet applied to the LFT, a Special Switch Port (SSP) of the first plurality of physical ports of the first subnet, or \n making the intra-subnet forwarding decision.
