  • Patent number: 9813362
    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.

  • Patent number: 9774461
    Abstract: A system for communicating a multicast packet through a network switch fabric is described. The system receives the multicast packet at an input port of the network switch fabric, where the multicast packet is directed to multiple output ports, and where the network switch fabric has a virtual output queue (VOQ)-based architecture, in which each input port maintains a separate VOQ for unicast packets to each output port and one or more VOQs for multicast packets destined to multiple output ports. The system sends the multicast packet by inserting the multicast packet into the one or more VOQs associated with the multiple output ports, so that multicast packets are queued separately from unicast packets. Moreover, the system may optionally dynamically modify a number of the one or more VOQs for the multicast packets based on a number of multicast flows through the network switch fabric.

  • Patent number: 9692704
    Abstract: A system for communicating packets through a network switch fabric is described. 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. The system also associates packet flows from the multiple sources with a global QoS bucket. The system monitors traffic rates for each QoS bucket in the set of QoS buckets and the global QoS bucket. The system determines a state for each QoS bucket by comparing a traffic rate for the QoS bucket with state-specific thresholds. The system also determines a state for the global QoS bucket by comparing a traffic rate for the global QoS bucket with state-specific global thresholds. When a packet is received for a given QoS bucket, the system performs an action based on a state of the given QoS bucket and a state of the global QoS bucket.

  • Patent number: 9590823
    Abstract: Implementations of the present disclosure involve an apparatus, device, component, and/or method for a hardware efficient flow to port affinity management table for link aggregation for a network fabric switch with Ethernet Gateway functionality. Rather than maintaining a state per traffic flow list, the present disclosure utilizes a handle or hash value derived from the traffic flow and associates an output port state to the hash value. The output port state for the hash value is further associated with a portlist that is based on at least a traffic flow policy of the server or group of servers associated with the traffic flow. In addition, the management table may be adjusted based on state changes to one or more of the output ports such that, if a port becomes unavailable, the management table may be adjusted to account for the unavailability of the port.
