cFosSpeed is a network driver, which attaches itself to existing Internet connections. It then optimizes data transfer by means of Traffic Shaping.

Traffic Shaping is a method for optimizing the Internet traffic. It allows maximum speed while ensuring minimal Ping.

You can use cFosSpeed with a router and/or a DSL-modem or cable-modem. You can also use cFosSpeed with other types of Internet access, ie. whenever you already have an existing Internet connection.

cFosSpeed supports a wide variety of connections, like DSL, cable, ISDN, UMTS, WIMAX etc.

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 DSL and cable, 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 512k. In short, huge window sizes just won't let you achieve full download speed.

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

Traffic Shaping technology does keep ping times low and transfer rates consistently high at the same time.

Still, to achieve optimal ping times, you should prioritize your game(s) as high as possible. You will find that we have already listed some of the currently most popular games under Program Settings. Should your game not be among the ones listed there, you can simply add it to the list.

If you are playing a game online without Traffic Shaping and run an upload or download at the same time, ping times to your gameserver will rise. Less data traffic means better (i.e., lower) ping. Especially with filesharing programs and other applications that send out lots of data, ping times often skyrocket resulting in serious lag. This will also slow down your in-game reaction time horrendously.

Traffic Shaping alleviates this problem by allowing filesharing and downloads to run in the background while gaming. This may still raise ping times minimally though. Therefore, we recommend you to keep "Favor Ping" activated at such times. By default, filesharing programs are set to very low priority. Now, this should not be taken to mean they are artificially slowed or even altogether stalled. What it does mean, however, is that such data will be briefly delayed when more important data like online game traffic needs to be transmitted. Only this priority scheme makes it possible to have filesharing programs run at maximum transfer rates while still using the same connection for other applications at the same time.

Thanks to cFosSpeed Traffic Shaping, you can finally use the full upstream bandwidth (with eMule, Kazaa or Bittorrent etc.) and make it available to other filenet users - without adversely affecting other Internet applications.

Running filesharing programs (like eMule, Kazaa or Bittorrent) will usually take up most if not all upstream channel bandwidth, which leaves the connection prone to high ping times. Not only does this mean filesharing communication itself will run slowly (source requests may take a full 1 or 2 seconds rather than just a few milliseconds), but it will also choke other Internet applications to a crawl. By the same token, download rates may plummet, since TCP ACKs are not being sent out in time. The browser will also become noticeably less responsive while surfing the Net.

A popular workaround offered by many filesharing programs is to put an artificial cap on the upload rate.

However, if you are simultaneously running a mail upload in addition to a filesharing upload, both will compete for available upstream bandwidth. How much bandwidth each of these uploads will eventually receive is basically left to happenstance. In some cases, this may even lead to termination of all TCP connections (TCP connection starving).

he priority scheme integrated in cFos and cFosSpeed (re)organizes data packets in a manner that ensures maximum download rates for filesharing programs. In addition, cFos and cFosSpeed deprioritize filesharing data transfer. Now, this should not be taken to mean such traffic is artificially slowed or even altogether stalled. What it does mean, however, is that such data will be briefly delayed when more important data is being transmitted. Only this priority scheme makes it possible to have filesharing programs run at maximum transfer rates while still using the same connection for other applications at the same time.

For instance, if you have a filesharing program running in the background when surfing the Net, there will only be a brief, minimal slowdown in P2P traffic while a new page is being loaded. Likewise, when sending out longer e-mails, P2P upload rates may briefly drop somewhat while the mail is being transmitted. Once the mail is sent, all uploads will continue at full speed again. The only alternatives would be to postpone transmission of the mail "forever" or artificially limit transfer bandwidth for filesharing somehow. But this would also mean a loss of bandwidth even when no other application is using the same connection.

cFosSpeed is thus optimized for use with filesharing (p2p) software, allowing users to have such a program run in the background without noticing its regular Internet activity.

Therefore, we suggest setting Kazaa etc. to "unlimited upload" while deactivating the "speed sense" option, since cFosSpeed will already optimize Internet traffic anyway.
