티스토리 뷰


온라인 게임할 때 핑이 높으면 렉 때문에 제대로 하지 못했을 것이다.
만약에 핑이 20ms 라면 프로그램을 이용하시면 약 16ms로 줄여 주기 때문에
인터넷 끊김 현상이나 렉 현상을 어느 정도 줄여 주기 때문에 안정된 속도로 인터넷을 즐길 수 있다.

또 자기가 가지고 있는 파일을 웹에 업로드 할 때나 공유 프로그램으로 공유할 때 속도가 일정하게 유지가 안 되고  왔다 갔다 한 경혐이 있을 것이다. 일정한 속도로 업로드나 공유할 수 있다.

20Mbps 이상의 VDSL급 이상의 환경에선 효과가 없을 수 있습니다

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 prioritizes data traffic in such a fashion that important packets zip past regular packets. This way, receipts always arrive in time, and uploads won't ever choke your broadband connection again! 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. With cFos Traffic Shaping, you will notice measurable improvements and benefits like:

* Full download rate during upload
* Consistently quick response time while surfing the Web or running other applications
* Improved VoIP speech quality
* Perfect for online gamers!
* Extended Traffic Shaping for DSL modems, cable modems & routers
* Highly responsive when used with online games and filesharing (P2P) like eMule, Kazaa or Bittorrent
