Abstract
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.
