1. A method of managing traffic for a virtual connection of a packet-based communications network, said method comprising the steps of:

  • transmitting packets from source equipment to destination equipment;

    time-division multiplexing the packets from the source equipment;

    measuring the data-rate of the multiplexed packets;

    temporarily storing said multiplexed packets in a queue;

    transmitting said stored packets over said virtual connection;

    determining a factor related to the rate at which packets are transmitted over said virtual connection towards said destination equipment; and

    transmitting said factor to a data-rate management processor to control the rate at which the packets are sent upstream from said multiplexing, wherein said factor is based on the length of said queue and the time taken to transmit said factor to said data-rate management processor to prevent said queue from overflowing.
