    Abstract: The disclosed embodiments relate to a system for communicating packets through a network switch fabric. During operation, at an aggregation point in the network switch fabric, the system segregates packet flows from multiple sources into a set of quality-of-service (QoS) buckets. Next, the system monitors traffic rates for each QoS bucket. The system then determines a state for each QoS bucket by comparing a traffic rate for the QoS bucket with one or more state-specific thresholds. When a packet is subsequently received for a given QoS bucket, the system performs an action based on a state of the given QoS bucket.

    Abstract: A system for communicating a multi-destination packet through a network switch fabric is described. The system receives the multi-destination packet at an input port of the network switch fabric, wherein the multi-destination packet is directed to multiple output ports, and wherein the network switch fabric has a virtual output queue (VOQ) architecture, wherein each input port maintains a separate VOQ for each output port. The system sends the multi-destination packet by inserting the multi-destination packet into VOQs associated with the multiple output ports. While inserting the multi-destination packet in each VOQ, if the VOQ is empty, the system inserts the multi-destination packet at a head of the VOQ. Otherwise, if the VOQ is not empty and if the VOQ contains an end of a last complete packet received by the VOQ, the system inserts the multi-destination packet into the VOQ at the end of the last complete packet.

    Abstract: The disclosed embodiments provide a system that operates a switch fabric. During operation, the system creates a set of virtual links for a first set of physical ports in the switch fabric. Next, the system uses a set of virtual port numbers to create a set of mappings between the set of virtual links and a second set of physical ports in the switch fabric, wherein the second set of physical ports is connected to the first set of physical ports using a single physical link. The system then uses the mappings to provide non-blocking behavior in traffic from the first set of physical ports to the second set of physical ports.

    Abstract: A system and method can support efficient packet processing in a network environment. The system can comprise a direct memory access (DMA) resources pool that comprises one or more of DMA resources. Furthermore, the system can use a plurality of packet buffers in a memory, wherein each said DMA resource can point to a chain of packet buffers in the memory. Here, the chain of packet buffers can be implemented based on either a linked list data structure and/or a linear array data structure. Additionally, each said DMA resource allows a packet processing thread to access the chain of packet buffers using a pre-assigned thread key.

    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.
