1. A method of controlling a packet switched network bandwidth which includes a plurality of multimedia transceiver for transferring multimedia communications from at least one multimedia transceiver to at least one other multimedia transceiver, wherein the method comprising the steps of:
- transmitting a first type of communication with a first bit rate;
transmitting a second type of communication simultaneously with said first type of communication for a predefined period of time;
calculating said network bandwidth for providing said network available bandwidth; and
adjusting packet transmission bitrate in accordance with said network available bandwidth for controlling said network bandwidth.

4. A method for controlling data transportation over a network, comprising the steps of:
-
a. transmitting data at a first bit rate;
b. detecting an available bandwidth of said network, said detection being in real time and substantially simultaneous with said transmission of data with a first bit rate; and
c. transmitting data at a second bit rate, said second bit rate being in accordance with said available bandwidth of said network that was detected in step (b). - View Dependent Claims (5)
