Buffering is used throughout high performance network systems to handle delays in the system. In general, buffer size will need to be scaled proportionally to the amount of data 'in flight' at any time. For very high performance applications that are not sensitive to network delays, it is possible to interpose large end to end buffering delays by putting in intermediate data storage points in an end to end system, and then to use automated and scheduled non-real-time data transfers to get the data to their final endpoints.

Maximum achievable throughput for a single TCP connection is determined by different factors. One trivial limitation is the maximum bandwidth of the slowest link in the path. But there are also other, less obvious limits for TCP throughput. Bit errors can create a limitation for the connection as well as RTT.

If the sender has not received acknowledgement for the first packet it sent, it will stop and wait and if this wait exceeds a certain limit, it may even retransmit. This is how TCP achieves reliable data transmission. Even if there is no packet loss in the network, windowing can limit throughput.

Because TCP transmits data up to the window size before waiting for the acknowledgements, the full bandwidth of the network may not always get used. The limitation caused by window size can be calculated as follows:. For a 4. But still everything stays exactly the same.

I have the feeling this has something to do with my router. The IP at the top of the SpeedGuide. Does this change something?

Thanks a lot. Connect your comp direct to the modem, bypassing your router, and test again. Unfortunately, my modem and router are one and the same. It's the SpeedTouch [i]. If things do not change after updating your modem's driver, I suggest you call your ISP to replace the modem.

Thanks a lot for your help. Replies: 9 Last Post: , PM. Replies: 2 Last Post: , PM. Replies: 11 Last Post: , PM. Replies: Last Post: , AM. By rmrucker in forum General Broadband Forum.
