Abstract:
A method for adaptive packet-length speech transport over a data network comprising the steps of:determining an end-to-end transmission delay between said first and second communication devices, including obtaining data from a server regarding a network topology of a network segment between said first and second communication devices; calculating a permissible packet length for transmission of voice information over a voice-over-data-network connection between said first and second communication devices at least partially based upon said end-to-end transmission delay, said step of calculating including calculating said permissible packet length based on an inverse correlation between packet length and said determined end-to-end transmission delay such that calculations of short permissible packet lengths are associated with determinations of long end-to-end transmission delays, said inverse correlation being determined prior to said transmission of said voice information; and transmitting voice information over said voice-over-data-network connection from said first communication device to said second communication device in a first set of packets having a length conforming to said permissible packet length.
