Abstract:
A method of processing sampled packets from a packet sender for transmission over a transmission system having a periodically allocated bandwidth to a packet recipient, the method comprising the steps of:determining unsolicited grant arrivals in response to a request from the packet sender; determining time needed between adjacent unsolicited grant arrivals for storing the sampled packets and for processing stored sampled packets; sampling voice packets by clocking packet sampling using a clock derived from and synchronized with a cable modem clock of a cable modem communicative with a cable modem termination system; scheduling processing of the stored sample packets to be ready for transmission at a next unsolicited grant arrival; and transmitting, upon receipt of an unsolicited grant arrival, processed sampled packets for further transmission to the packet recipient over the transmission system having a periodically allocated bandwidth; wherein the step of determining time needed includes the step of counting time between unsolicited grant arrivals and upon reaching a count indicative of the interval between unsolicited grant arrivals, providing for transmission of the currently stored sampled packets at the next unsolicited grant arrival.
