Abstract:
1. A method of controlling packet delay through a packet buffer of a digitized packet-based transmission network, said packet buffer being operative to store packets received from said network and to controllably read out packets therefrom for application to a digitized packet signal processor, said method comprising the steps of: (a) establishing a nominal value of buffer delay through said packet buffer for packets received from said network; and (b) in response to an increase in delay in receipt of packets from said network, increasing buffer delay from said nominal value to an increased buffer delay and maintaining said increased buffer delay value in the absence of a further increase in delay in receipt of packets from said network, and thereafter iteratively further increasing said buffer delay, as necessary, for any further increase in delay in receipt of packets from said network, so that the value of buffer delay is adjusted as necessary to a delay value sufficient to accommodate the maximum encountered transport delay through said network.
