摘要： A first set of instructions associated with an egress of a datagram may be determined, the first set of instructions identifying a first subset of a second set of instructions, the first subset including multiple individual network identifiers identifying which network portion to transmit a replication of the datagram. Which one of the multiple individual network identifiers corresponds to the datagram may be determined from the first subset of the second set of instructions and may be based on the egress of the datagram, wherein each network identifier corresponds to a different egress. The replication of the datagram may be provided to the egress of the determined network identifier for transmission to the network portion as identified by the determined network identifier corresponding to the datagram.

摘要： A method and a system for allocating memory in a memory buffer that is part of a data distribution device. Generally, the allocation of memory is for the purpose of storing datagrams. The method allocates memory in the buffer based, at least partially, on how ingress ports that are operably connected to the memory buffer have previously used the buffer to store datagrams. The system typically includes one or more detectors that monitor how various ingresses into the data distribution device are using and have used the memory buffer.

摘要： A network device for scheduling packets in a plurality of queues includes a plurality of leaky bucket modules, each of the plurality of leaky bucket mechanisms being associated with one of a plurality of queues and configured to process information based on a predefined bandwidth, a scheduler configured to schedule services of the plurality of queues and a metering module for tracking whether or not the plurality of queues has exceeded a predefined threshold through the leaky bucket modules. If the plurality of queues has exceeded the predefined threshold, the metering module is configured to compute a new bandwidth allocation for each of the plurality of queues, the new bandwidth allocation replacing the predefined bandwidth and being proportional to the predefined bandwidth for each of the plurality of queues.
