Anbefales: ADSL+CFOS Speed

"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 won´t let you achieve full download speed.

 

By contrast, cFos Traffic Shaping takes a different approach. It prioritizes data transfer in such a fashion that all important data packets (along with the ACKnowledgment packets) will just speed past regular packets. In effect, this means uploads will no longer congest the DSL connection.

 

cFos Traffic-Shaping technology recognizes a number of important packet types and prioritizes them to keep Internet traffic running smoothly, which does in turn result in particularly low ping times. This not only accelerates surfing and download speeds significantly, but it is also a decisive advantage for online gaming.

Jeg kan skrive under på at dette fungerer! Jeg har lenge irritert meg grønn over ADSL-linjen ble nesten ubrukelig ved upload av filer, spesielt hvis jeg hadde P2P klient i bakgrunnen. Etter installering av CFOS speed merkes det knapt at uplink kanalen er belastet. Anbefales!
