Abstract
Packet production by a digital signal processor (DSP) is synchronized with modem transmission opportunities in a cable network. The cable modem computes the average waiting time a packet spends waiting to be transmitted by the modem. The DSP re-syncs transfer of packets to the modem by using this average waiting time minus a small amount sufficient to account for the maximum anticipated propagation delay, as the amount to delay the transmission of its next packet to the cable modem. This invention is a mechanism for re-synchronization that is largely independent of any propagation delays inherent in the hardware architecture.
