摘要： A method and apparatus are provided for scheduling unicast and multicast data in an input-queued network device. According to one aspect of the present invention, a combined schedule is created by pipelined staging of multicast and unicast scheduling. Multicast cells are scheduled for transmission among multiple interfaces of a crossbar by performing a multicast cell scheduling cycle for multiple classes of service that are supported by the network device. Then, unicast cells are scheduled for transmission among the interfaces at a lower priority than the previously scheduled multicast cells by performing a unicast cell scheduling cycle for the multiple classes of service using only those interfaces that remain unmatched after completion of the multicast cell scheduling cycle.

摘要： A scheduling device for managing a packet queue of a communication gateway includes a receiving portion configured to receive data packets according to at least one communication protocol, a processor, and classification module configured to separate the received data packets into a first traffic queue and a second traffic queue separate from the first traffic queue. The first traffic queue includes a low latency service flow classified to have strict priority. The second traffic queue includes a primary service flow classified as having a classic priority.

摘要： One embodiment includes multiple distribution nodes sending packets of different ordered sets of packets among multiple packet switching devices arranged in a single stage topology to reach a reordering node. The reordering node receives these packets sent over the different paths and stores them in reordering storage, such as, but not limited to, in queues for each distribution node and packet switching device combination. The reordering node sends packets stored in the reordering storage from the reordering node in original orderings. In response to determining that an aggregation quantum of packets received from the multiple distribution nodes via a particular packet switching device and stored in the reordering storage is outside a range or value, packets being communicated via the particular packet switching device to the reordering node are rate limited.

摘要： Systems and methods for systematic hybrid network scheduling for multiple traffic classes with host timing and phase constraints are provided. In certain embodiments, a method of scheduling communications in a network comprises scheduling transmission of virtual links pertaining to a first traffic class on a global schedule to coordinate transmission of the virtual links pertaining to the first traffic class across all transmitting end stations on the global schedule; and scheduling transmission of each virtual link pertaining to a second traffic class on a local schedule of the respective transmitting end station from which each respective virtual link pertaining to the second traffic class is transmitted such that transmission of each virtual link pertaining to the second traffic class is coordinated only at the respective end station from which each respective virtual link pertaining to the second traffic class is transmitted.

摘要： An approach, executed by a computer, includes receiving at least an initial polling quantity and an initial polling frequency and polling an endpoint application using the initial polling quantity and the initial polling frequency. The approach includes determining a first number of events not consumed in a queue of a listening application and a second number of events generated at the endpoint application and remaining in a queue at the endpoint application and comparing the number of events in each queue. The approach includes adjusting at least one of the initial polling quantity and the initial polling frequency based, at least in part, on the comparison of the first number of events not consumed in the queue of the listening application and the second number of events generated at the endpoint application and remaining in the queue at the endpoint application.

摘要： In an apparatus for receiving and forwarding data packets on a network, a network device includes a plurality of ports for coupling to the network and for transmitting packets to devices disposed in or coupled to the network. At least one processor configured to process packets received via the network processes packets by selectively forwarding processed packets to one or more of the ports. A plurality of queues are defined in a memory, each configured to store packets to be transmitted by ports in the plurality of ports. A queue manager is configured to selectively assign a subset of the plurality of queues to a subset of the plurality of ports.

摘要： A network node comprises an optical input, an optical output, a random-access queue and a processing system. It receives a data packet, at the optical input and determines whether to process it as a guaranteed-service packet or as a statistically-multiplexed packet. A guaranteed-service packet is output within a predetermined maximum time of receipt, optionally within a data container comprising container control information. A statistically-multiplexed packet is queued. The node determines a set of statistically-multiplexed packets that would fit a gap between two guaranteed-service packets; selects one of the packets; and outputs it between the two guaranteed-service packets.
