Abstract: An input/output (I/O) switch fabric includes input physical ports that convey packets associated with at least a first network flow. Moreover, virtual routers in the I/O switch fabric, which have associated routing tables, provide types of service and/or routes for different source-destination pairs based on link-layer information and network-layer information in the packets. Note that different virtual routers can provide different types of service and/or different routes. For example, a type of service associated with a first virtual router may include changing packet headers when crossing service domains in a global network, and a type of service associated with a second virtual router may avoid changing packet headers when providing connectivity in the network. Furthermore, the I/O switch fabric includes output physical ports that convey packets associated with at least a second network flow. The virtual routers may facilitate InfiniBand inter-subnet crossing.

Abstract: A system and method can support efficient packet processing in a network environment. The system can comprise a thread scheduling engine that operates to assign a thread key to each software thread in a plurality of software threads. Furthermore, the system can comprise a pool of direct memory access (DMA) resources that can be used to process packets in the network environment. Additionally, each said software thread operates to request access to a DMA resource in the pool of DMA resources by presenting an assigned thread key, and a single software thread is allowed to access multiple DMA resources using the same thread key.

Abstract: An input/output (I/O) switch fabric includes first physical ports that convey multiple network flows. Moreover, classifiers in the I/O switch fabric separate packets for network flows associated with different types of service. Then, the I/O switch fabric conveys the packets to different virtual switch ports without interference between the separated packets associated with different network flows. Furthermore, second physical ports in the I/O switch fabric output the packets, where a given second physical port outputs packets for at least some of the network flows associated with different types of service. In this way, the given second physical port can output packets having: the same source and destination; different sources and the same destination; or the same source and different destinations.

Abstract: An InfiniBand switch fabric is described. This InfiniBand switch fabric includes a hierarchy of switches having physical ports. These physical ports have associated local routing tables for nearest-neighbor connections to the physical ports. Moreover, relationships between the nearest-neighbor connections to each of the physical ports specified in the local routing tables are based in part on network-layer global identifiers that are assigned based on the hierarchy. Furthermore, local routing tables in the switches facilitate paths or routes for packets through the InfiniBand switch fabric without using a global routing table in the switches. In addition, the InfiniBand switch fabric includes a fabric manager, coupled to the switches, having the global routing table to assign the network-layer global identifiers.
