1. A system for providing site independent real-time multimedia transport over packet-switched networks comprising:

  • a network;

    a first node selected from a group of nodes wherein said first node is coupled with said network and wherein said first node comprises;

    a packet store;

    an automatic repeat request module coupled with said packet store;

    a time clock; and

    , a timing synchronizer configured to time stamp a first packet and a second packet obtained from said automatic repeat request module with a time parameter obtained from said time clock;

    a plurality of second nodes selected from said group of nodes wherein said plurality of second nodes are coupled with said network and wherein said plurality of second nodes comprises;

    a receiver time clock;

    a receiver timing synchronizer coupled with said receiver time clock;

    a clock recovery module coupled with said receiver timing synchronizer;

    a receiver automatic repeat request buffer;

    a receiver automatic repeat request module coupled with said receiver automatic repeat request buffer;

    said first node configured to transmit to said plurality of said second nodes; and

    , said plurality of second nodes configured to restore packet order, remove jitter and recover lost packets and where said each of said plurality of second nodes further comprise a network monitor configured to calculate and update a minimum hold time based on network jitter and round-trip time.
