Methods and arrangements are disclosed for transferring digital data over a limited speed communications link between a client side subarrangement ( 401 ) and a server side subarrangement ( 402 ). Within the client side subarrangement ( 401 ), a client application ( 411, 502 ) receives and transmits digital data using a first communications protocol stack ( 412, 503, 504, 505 ) and, within the server side subarrangement ( 402 ), a server application ( 426, 572 ) receives and transmits digital data using the first communications protocol stack ( 425, 573, 574, 575 ). Digital data is transferred between the client application ( 411, 502 ) and the server application ( 426, 572 ) through a client proxy ( 511 ) within the client side subarrangement ( 401 ) and an access gateway ( 551 ) within the server side subarrangement ( 402 ). Said client proxy ( 511 ) performs protocol conversations between the first communications protocol stack ( 412, 503, 504, 505 ) and a second communications protocol stack ( 415, 521, 522, 523, 524, 525, 526 ) that provides a bandwidth efficiency that is better than a bandwidth efficiency to which the first communications protocol corresponds.
