the processor is further configured to transfer the requested data stored in the cache to the destination communication terminal, via the communication network, by performing the mode of window control defined by the control parameter.

9. The relay device of claim 7, wherein the processor is further configured to insert the selected control parameter into the request for data message, and thereafter relay the request for data message containing the selected control parameter to the transmitter device.

17. The relay device of claim 7, wherein the selected control parameter for determining the window size for the mode of window control includes an initial window size;

and

wherein to direct the at least one of the transmitter device and the communication interface of the relay device to transmit the requested data via the communication network to the destination communication terminal based upon the mode of window control defined by the selected control parameter comprises;

the processor configured to direct the at least one of the transmitter device and the communication interface of the relay device to transmit the requested data based upon the initial window size.

18. The relay device of claim 7, wherein the attribute for determining the window size for the mode of window control includes a window size increment attribute;

and

wherein to direct the at least one of the transmitter device and the communication interface of the relay device to transmit the requested data via the communication network to the destination communication terminal based upon the mode of window control defined by the selected control parameter comprises;

the processor configured to direct the at least one of the transmitter device and the communication interface of the relay device to transmit the requested data based upon the window size increment attribute.

10. A system for communication between a transmitter device and a terminal device on a network comprising:

a relay device and a data server configured to intercommunicate via a communication network, the relay device including a control parameter management table, wherein the control parameter management table includes a plurality of initial window size parameters, wherein each of the initial window size parameters defines a mode of window control to be performed during data transmission of data through the communication network;

the relay device is further configured to receive a request for data message that specifies requested data to be sent through the communication network to a communication terminal, wherein the relay device is further configured to determine a model type of the communication terminal based upon the request for data message;

the relay device is further configured to select an initial window size parameter from the control parameter management table as a function of the model type of the communication terminal; and

the relay device is further configured to direct at least one of the relay device and the data server to control transmission of data requested to the communication terminal as a function of the mode of window control defined by the initial window size parameter.
