Claim:
1. A method for controlling network traffic congestion in a telecommunication path between a wired segment server employing TCP protocols and a host operating system on a first side and a wireless mobile client employing a client operating system and a mobile client on a second side of the telecommunication path, comprising: providing an intermediate accelerator apparatus between the wired segment server and the mobile client device in the telecommunication path without modification to the wired segment server, to the host operating system, to the wireless mobile client and to the client operating system; measuring, via the intermediate accelerator apparatus inserted between the wired segment server and the mobile client device, reception timings of packets; at the intermediate accelerator apparatus, buffering TCP incoming packets from the wired segment server and immediately returning TCP ACKs to the wired segment server, the TCP ACKs reporting receiver window size according to the buffer availability at the accelerator device rather than the buffer availability of the wireless mobile client; controlling packet transmission from the accelerator apparatus to the mobile client irrespective of window size, unless the window size is zero or below a defined threshold, by rate based congestion control, thereby using only the intermediate accelerator apparatus to control packet transmission between the wired segment server and the mobile client.
