Abstract:
1. A method of carrying packetized voice data over a data network, the method comprising: aggregating multiple datagrams bound for a common intermediate switching point into a tunnel packet payload, each datagram comprising a voice data payload from a selected voice data stream and a compressed header-formatted header from which—when combined with information from one or more previous datagram headers from the same voice data stream—the datagram's destination endpoint can be derived; encapsulating the tunnel packet payload in a tunnel packet having a tunnel header and forwarding the tunnel packet to the intermediate switching point; and deaggregating the tunnel packet payload at the intermediate switching point and assigning the datagrams to new tunnel packet payloads based on a destination endpoint derived from each datagram's header and one or more previous datagram headers from the same voice data stream; wherein the tunnel header is configured so that a packet-switched network device routing or forwarding packets according to a network address does not reference the tunnel packet payload.
