Data packet transmission

A server for communicating with terminals wherein packets of data are transmitted from said server to said terminals, and wherein said server is configured to

• transmit a plurality of data packets to a terminal at a first rate of transmission;
• receive acknowledgement data from said terminal to acknowledge the receipt of data packets at said terminal;
• retransmit data packets that are not acknowledged to said terminal;
• monitor a packet retransmit requirement;
• and
• adjust said rate of transmission from said first rate to a second rate in response to an output of a control procedure that receives said packet retransmit requirement as an input.

A terminal for communicating with a server wherein packets of data are transmitted from said terminal to said server, and wherein said terminal is configured to

• transmit a plurality of data packets to a said server at a first rate of transmission;
• receive acknowledgement data from said server to acknowledge the receipt of data packets at said server;
• retransmit data packets that are not acknowledged to the server;
• monitor a packet retransmit requirement;
• and
• adjust said rate of transmission from said first rate to a second rate in response to an output of a control procedure that receives said packet retransmit requirement as an input.

Instructions executable by a network of computers and/or programmable data processing devices such that when executing said instructions stations connected to said network will transmit data over said network, such that said network performs the steps of:

• transmitting a plurality of data packets from said first station to said second station at a first rate of transmission;
• returning acknowledgement data from said second station to said first station to acknowledge the receipt of data packets at said second station;
• retransmitting data packets that are not acknowledged from said first station to said second station;
• monitoring, at said first station, a packet retransmit requirement;
• and
• adjusting, at said first station, said rate of transmission from said first rate to a second rate in response to an output of a control procedure that receives said packet retransmit requirement as an input.

Instructions executable by a combination of a server and mobile terminals connected to said server over a radio network, such that when executing said instructions said combination performs the steps of:

• transmitting a plurality of data packets from said server to a network connected terminal at a first rate of transmission;
• returning acknowledgement data from said terminal to said server to acknowledge the receipt of data packets at said terminal;
• retransmitting data packets that are not acknowledged from said server to said terminal;
• monitoring, at said server, a packet retransmit requirement;
• and
• adjusting, at said server, said rate of transmission from said first rate to a second rate in response to an output of a control procedure that receives said packet retransmit requirement as an input.

A computer readable medium having machine-readable instructions executable by a computer such that when executing said instructions a computer will perform the steps of:

• transmitting a plurality of data packets to a networked device at a first rate of transmission;
• receiving acknowledgement data from said networked device to acknowledge the receipt of data packets at said terminal;
• retransmitting data packets that are not acknowledged to said terminal;
• monitoring retransmit information;
• and
• adjusting said rate of transmission from said first rate to a second rate in response to an output of a control procedure that receives said retransmit information as an input.
