摘要： Reducing memory access bandwidth consumption in a hierarchical packet scheduler. A hierarchical packet scheduler is maintained, wherein the hierarchical packet scheduler includes one or more levels, each level including one or more schedulers, wherein one or more threads serve each level. Scheduling operations are performed at each scheduler of the hierarchical packet scheduler by reading a portion of scheduler state from external memory.

摘要： A method and apparatus for sorting packets by packet schedulers using a connected trie data structure is described. According to one embodiment of the invention, the packet scheduler receives a packet on a network and assigns the packet a time stamp value. The packet is inserted into a trie data structure that represents a scheduling horizon and includes a plurality of packets. The packet scheduler transmits the packet over the network based on its sorted order within the trie data structure.

摘要： Bandwidth is allocated by leveraging a bursty characteristic of data transmission signals to efficiently utilize network resources. Network performance is observed over a time period to identify patterns of data transmission rates as different signals are processed. To compensate for the fact that different jobs/tasks peak at different times, the total bandwidth limit may be increased by a scaling factor. The scaling factor is calculated using information obtained by observing network performance during the time period. The scaling factor is used to increase the total bandwidth available for all jobs/tasks executing during the time period without exceeding any bandwidth limits. The data transmission rate of each job/task may then be adjusted to utilize the newly available bandwidth.
