For each connection, you can adjust the following settings:

• Traffic Shaping Mode (Multi-User version)
• Medium/Protocol

Traffic Shaping Mode (Multi-User version)

Not cooperative - There is a machine without cFos TS on your LAN
You use your connection with several other machines simultaneously and at least one of them has no cFos Traffic Shaping.

網路交談 - Broadcast traffic statistics on your LAN
為了加強準確度，傳送流量塑型統計資料到您的區域（家庭）網路上其它電腦。（沒有送出任何資料到網際網路）

Ping Variance - 適應多變的反應時間
蒐集反應的統計資料來適應多變的反應時間，在移動/無線網路上特別有用。

• How all three settings work together

Medium/Protocol

• Adaptive: cFos/cFosSpeed will adapt to your connection automatically. Use this setting only if you are not sure what your connection type is. Otherwise, select the setting that applies to your connection. The better the chosen setting fits your connection type, the lower ping times should be.
• DSL (PPPoE): Most widespread DSL protocol (commonly used in the USA, Germany, Eastern Europe, and other major markets).
  PPPoE explanation @ wikipedia.org
• DSL (PPPoA/Vcmux): Common standard in Great Britain.
  PPPoA explanation @ wikipedia.org
• DSL (PPPoA/LLC): Occasionally used in Great Britain
  PPPoA explanation @ wikipedia.org
• DSL (PPTP): Older DSL standard still in use in some parts of France.
  PPTP explanation @ wikipedia.org
• Cable: Internet via TV cable with bandwidth varying slightly according to usage and time of day.
  Cable technique @ wikipedia.org
• ISDN: 8 or 16 kbytes, bidirectional, PPP in HDLC frames
  ISDN explanation @ wikipedia.org
• IP over AAL5: IP data transfer via ATM
  ATM Adaptation Layer @ wikipedia.org
• RFC 1483/2684: DSL over ATM bridging
• Frame Count: Transfer speed varies with the number of data packets transmitted per time interval. Sometimes used in Greece.
• Mixed Raw IP/Frame Count: Downstream traffic is handled as in "Frame Count", upstream traffic as in "Cable". Used by some cable providers like ish.

Set up the right medium/protocol if you know exactly which transfer medium/protocol is used. If in doubt, use Adaptive.

我如何才能更好的对 cFos 或 cFosSpeed 的调整尺度进行优化呢？

• 点击“清除调整尺度数据”清空通信量调整的相关数据和内容
• 进行短时的全速下载（大约持续 5 至 10 秒钟即可）
• 进行长时全速上传（大约持续 30 秒至 1 分钟）
  在这个过程中，请尽量让上传速度达到最大，以便于进行测定。例如，可以通过发送数据到最近的服务器（你的邮件服务器或 FTP 服务器）。同时，在上传过程中不要进行任何的下载。如果你的上行速率是 256 kbit/s，你可以发送大概 2 MB 的文件来进行测试。
• 按照这样的方式，通信量调整功能将会对你的网络连接进行测试和调整，此时你就可以在上传满速的时候，保持让 Ping 时间处于较低的水平。这些你都可以在状态窗口中看到。
