Abstract: Upstream burst transmit times are dynamically communicated to the transmit unit in grants issued over time and in any order. A critical parameter is when to trigger the operation to order the buffered data stream for transmission. If the ordering operation is triggered too soon, a later grant of an earlier burst transmit time may not be accounted for and the subsequent transmission could violate the transmission order rule. If the ordering operation is triggered too late, the decision to transmit a burst at an earlier burst transmit time may violate the margin rule. To address these concerns, a fetch offset time in advance of each granted burst transmit time is assigned. As each fetch offset time is sequentially reached, a next partial data portion of the buffered data stream is prepared for burst communication.
