摘要
Packet production by a digital signal processor (DSP) (16) is synchronized wiith modem transmission opportunities in a cable network. The cable modem (17) computes the average waiting time a packet spends waiting to be transmitted by the modem (17). The DSP (16) re-syncs transfer of packets to the modem (17) 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 (17). This invention is a mechanism for resynchronization that is largely independent of any propagation delays inherent in the hardware architecture.
