Claim 13:
14. A method of increasing responsiveness of a server using a Transmission Control Protocol (TCP) connection comprising:
A) opening the TCP connection to receive and send TCP data packets, comprising:
(i) receiving at a server a first request for a first image data file over a network from a client;
(ii) sending from the server to the client a first image data file in response to the first request;
(iii) sending from the server to the client a first timestamp at a first time (t1);
(iv) receiving at the server from the client at a second time (t2) the first timestamp;
(v) determining a first difference (d1) given by t2 less t1;
(vi) receiving at the server a request for extra TCP data packets;
(vii) sending from the server to the client a second timestamp at a third time (t3);
(viii) receiving at the server from the client at a fourth time (t4) the second timestamp;
(B) determining a second difference (d2) given by t4 less t3;
(C) calculating an extra travel time (e) given by d2 less d1;
(D) calculating best based on a plurality of measurements of bread, where bread is given by C/T, where C is an amount of data bits of information that was read in a time elapsed between ci and ci-1, where C=ci−ci-1 and T is a time elapsed between ti and ti-1, where T=ti−ti-1+e; and
(E) if the amount of data bits of information is greater than 10 kilobytes and e exceeds a threshold emax, then reducing a send bandwidth to blimit where bsend=max(f1*best, f2*blimit), where f1 and f2 are factors thereby increasing server-client responsiveness of requested data files.
