cFos Traffic Shaping reduces delays during data transfer and allows you to surf the Internet up to three times faster. Finally, you can use the full bandwidth of your DSL connection!

During TCP/IP transfer, a certain amount of data needs to be confirmed upon reception before more can be sent. Stalling data confirmation results in delays and transfer-rate slowdowns, thus forcing the sender to wait. Especially for ADSL, it is possible to slow a download to a crawl by choking the upstream channel (which has the smaller bandwidth anyway) with an upload. This is because in such a scenario there is not enough upstream bandwidth left for data confirmation.
The standard solution so far has been to try and compensate for this by increasing TCP window size, thereby allowing more data to be sent without immediate confirmation. The main problem here is that this also leads to high ping times (latency) and significant delays during Webpage rendering. Latency of up to 2 seconds is not uncommon for TCP windows with a size of 64k. In short, huge window sizes just wonґt let you achieve full download speed.
