    摘要： There is provided a method for adaptive data transfer over packet networks. The method comprises selecting a first communication path for transferring the data to the second computer, starting to transfer the data over the first communication path to the second computer, monitoring transfer characteristics of the first communication path related to the data transfer, storing the transfer characteristics associated with the first communication path in a database, comparing the transfer characteristics against one or more previously stored transfer characteristics related to one or more prior data transfers, and determining whether to alter a transfer algorithm being utilized for transferring the data to the second computer based on the comparing.

    摘要： Shared memory management apparatus and techniques are disclosed. A shared memory provides queues for storing communication traffic that is to be scheduled for transmission. Based on amounts of communication traffic stored in the queues, a determination is made as to whether or not communication traffic is to be removed from the shared memory, and if so, communication traffic is removed. Traffic may be selected for removal based on one or more of: a scheduling algorithm for scheduling communication traffic out of the queues for transmission, thresholds associated with the queues, and latency of the communication traffic stored in the queues. Removal of communication traffic from the shared memory is coordinated with scheduling of communication traffic in some embodiments.

    摘要： A network node (5) including a line card (20) for packet-based data communications is disclosed. The line card (20) includes a transmit FIFO buffer (24T) and a receive FIFO buffer (24R), for buffering communications within the line card (20). Each of the buffers (24T, 24R) operate in a dual-port fashion, receiving asynchronous read and write requests, for reading data words from and writing data words to the buffers (24T, 24R). The buffers (24T, 24R) each include a memory array (45) of conventional single port random access memory cells, for example static RAM cells. Clock cycles are assigned by the buffers (24T, 24R) as internal read and internal write cycles, in alternating fashion. A write buffer (42) receives input data words, and schedules a double-data-word write to the memory array (45) upon receiving a pair of input data words, in the next internal write cycle. A read request buffer (44) receives read strobes, or read enable signals, from a downstream function, and upon receiving two such strobes, schedules the read of a double-data-word from the memory array (45). By converting the asynchronous read and write requests into scheduled reads and writes, respectively, the buffers (24T, 24R) operate as dual-port FIFO buffers.
