Patent ID: 7162535

Claim:
An arrangement for transferring digital data over a limited-transmission-capacity communications link, comprising: a client side subarrangement, a server side subarrangement located at a different side of the limited-transmission-capacity communications link than the client side subarrangement, within the client side subarrangement, a client application arranged to receive and transmit digital data using a first communications protocol stack, and within the server side subarrangement, a server application arranged to receive and transmit digital data using the first communications protocol stack; within the client side subarrangement, a client proxy arranged to perform protocol conversions between the first communications protocol stack and a second communications protocol stack, and within the server side subarrangement, an access gateway arranged to perform protocol conversions between the first communications protocol stack and the second communications protocol stack; wherein: said client proxy and said access gateway are arranged to convey transferred digital data between the client application and the server application so that, between said client proxy and said access gateway, digital data are transferred according to the second communications protocol stack, and said second communications protocol stack corresponds to a bandwidth efficiency that is higher than a bandwidth efficiency to which the first communications protocol stack corresponds.
