摘要： An information handling system includes a plurality of sequentially connected units including a first unit, a second unit and a third unit. Packets of information flow from the first unit directly to the second unit and then to the third unit, and each of the plurality of units provides a respective dynamic output indication indicating if that unit output a packet. The information handling system further includes a control unit that determines, utilizing all of the plurality of dynamic output indications, packet buffering capacities of the plurality of units, and guaranteed packet flows between adjacent ones of the plurality of units, if the first unit can output a packet directly to the second unit without packet loss. In response to this determination, the control unit outputs a control signal to the first unit.

摘要： An information handling system includes a producer that outputs packets, a buffer that receives packets from the producer, buffers the packets, and eventually outputs the packets, and a control unit that controls the flow of packets from the producer to the buffer. The control unit receives as inputs a producer output indication indicating that the producer has output a packet to the buffer and a buffer output indication indicating that the buffer has output a packet. Based upon a capacity of the buffer, a number of the producer output indications, a number of buffer output indications, and a number of grant messages output to the producer within a feedback latency of the control unit, the control unit whether the producer can output a packet without packet loss. In response to a determination that the producer can output a packet without packet loss, the control unit outputs a grant message to the producer indicating that the producer is permitted to output a packet.

摘要： An information handling system includes a plurality of producers that output packets of information, at least one consumer of the packets, and an information pipeline coupling the consumer and at least a particular producer among the plurality of producers. The information pipeline includes a shared resource having a bandwidth shared by multiple of the plurality of producers. The information handling system further includes a control unit that regulates packet output of the particular producer and that receives as inputs a producer output indication indicating that the particular producer output a packet and a shared resource input indication indicating that a packet output by the particular producer has been accepted by the shared resource for transmission to the consumer. Based upon these inputs, a number of grant messages output to the particular producer within a feedback latency of the control unit, and a portion of the bandwidth allocated to the particular producer, the control unit whether the particular producer can output a packet without packet loss. In response to a determination that the particular producer can output a packet without packet loss, the control unit outputs a grant message to the particular producer indicating that the particular producer is permitted to output a packet.

摘要： An information handling system includes a producer that outputs packets of information, a plurality of buffers that can each receive packets from the producer and output the packets, and a control unit. The control unit receives at least one producer output indication indicating whether the producer output a packet to one of the plurality of buffers and a plurality of buffer output indications that each indicate whether a respective one of the plurality of buffers has output a packet. Based upon capacities of the plurality of buffers, the producer output indications, the buffer output indications and a number of grant messages output to the producer within a feedback latency of the control unit, the control unit whether the producer can output a packet without packet loss. If so, the control unit provides a grant message to the producer indicating that the producer is permitted to output a packet.
