cFosSpeed是一个被附加在现有互联网连接上的网络驱动程序。它通过网络流量管理来优化数据传输。网络流量管理是一种优化互联网流量的方法，它可以在允许最大速度的同时保证最低的Ping值。
cFosSpeed可以用在路由器，DSL调制解调器或者电缆调制解调器的连接上。它还可以用在其它类型的互联网连接上，只要你有现有连接。cFosSpeed支持多种连接类型，比如DSL，Cable，ISDN，UMTS等。
更新日志：
+ Added new skin: "LC History"; it's like our well-known Liquid Crystal skin, but with a history that scrolls to the left.
+ Added Layer-7 detection for large HTTP downloads (client & server). HTTP transfers which take more than 1 sec. at full speed are now classified as HTTP_C_BULK / HTTP_S_BULK and have low priority as default. You can change the priority in the Layer-7 Protocol prioritization dialog. Warning: This will only work, if the current HTTP connection is not reused by the browser. Otherwise the first classification will be used. The next version will remove this limitation.
+ Speeded memory allocation.
+ Improved detection of packets that NDIS sends erroneously to cFosSpeed.
x Added better handling of multiple but different SYN segments and improved recovery after ACK for unsent data. Thanks to khashayar zayyani for help.
x Fixed a crash with Cisco Systems VPN Client. Thanks to Hardi Trenkel for crash dump file.
x Adapters were sometimes unbound too fast, which caused Windows problems. Fixed.
x It seems some networks trash the Ping IP packet when they return it to the sender and cFosSpeed couln't find the replies in its lists. Thus, we relaxed the check a bit. Thanks to Deepak for bug report.
x Tried to fix problem with socket error sending pings that caused ping balloons. Thanks to yen linh for report.
x Fixed a bug where cFosSpeed would not properly reset the 'bridged' setting when the router resets while cFosSpeed is running. Thanks to 4wd for bug report and testing.
x Sometimes HTTP, SSL and SSH non-BULK l7-protocols would stay on default priority even if the l7-protocol priority was set to high. Fixed. Thanks to mumia for bug report.
x Fixed a crash under Vista that would close spd.exe. Thanks to SyntaX.
x Fixed x64 installer: now it pops up UAC dialog under Vista to make you full Admin. This bug was introduced in build 1433.
x Fixed some Windows object security problems.
x L7 protocols SSL_C, SSL_S and SSH sometimes switched between _BULK and regular versions periodically. This has been amended.
- Removed obsolete NDIS handler.
- Removed speed.gadget from distribution. It can now be downloaded from our website.
