摘要： An edge network device controls the quality-of-service of incoming network traffic flows by limiting the bandwidth of incoming network traffic flows. To ensure that incoming network traffic classes quickly converge to the desired bandwidth allocations, the maximum bandwidth allocation to each network traffic class is dynamically varied based on current overall usage. The maximum bandwidth allocated to each traffic class at any given moment is the sum of its minimum guaranteed bandwidth and a portion of the available excess bandwidth. Each traffic class' portion of the excess bandwidth is proportional to the ratio between its minimum guaranteed bandwidth and the sum of all traffic classes' minimum guaranteed bandwidths. Phantom network packets equivalent to the difference between each traffic class' allocated and actual bandwidth may be added to its scheduling queue to implement this dynamic variation. Phantom packets occupy transmission slots during packet scheduling and are discarded when selected for transmission.

摘要： A method and apparatus are provided for scheduling a heterogeneous communication flow. A heterogeneous flow is a flow comprising packets with varying classes or levels of service, which may correspond to different priorities, qualities of service or other service characteristics. When a packet is ready for scheduling, it is queued in order in a flow queue that corresponds to the communication flow. The flow queue then migrates among class queues that correspond to the class or level of service of the packet at the head of the flow queue. Thus, after the head packet is scheduled, the flow queue may be dequeued from its current class queue and requeued at the tail of another class queue. If the subsequent packet has the same classification, it may be requeued at the tail of the class queue or may remain in place for another servicing round.
摘要翻译：提供了一种用于调度异构通信流的方法和装置。异构流是包括具有不同等级或级别的服务的分组的流，其可以对应于不同的优先级，服务质量或其他服务特征。当一个数据包准备好进行调度时，它会在与通信流对应的流队列中排队。然后，流队列在对应于在流队列的头部处的分组的类或服务级别的类队列之间迁移。因此，在头分组被调度之后，流队列可以从其当前类队列出队并在另一队列的尾部重新排队。如果后续分组具有相同的分类，则可以在类队列的尾部重新排列，或者可以保留在另一个维修周期的位置。

摘要： A method and apparatus for implementing a Multipoint Infrastructure Transport (MINT) protocol in a data network. The present invention includes a method for distributing data in a data network. The data network connects a plurality of nodes and at least a portion of the plurality of the nodes form a multicast group. One of the nodes in the multicast group is designated as a rendezvous node. The method includes a step of maintaining a data store containing a group state at each of the nodes in the multicast group. State updates, received at the rendezvous node are used to update the group state in the data store at the rendezvous node. The state updates are propagated, using a reliable protocol, from the rendezvous node to the other nodes in the multicast group. Finally, the group states in the data stores at the other nodes in the multicast group are updated.
