cFosBC是一个在高带宽互联网上的高性能拨号驱动。Windows自带驱动传送数据时速度只能达到4.5Mbyte/s，而使用cFosBC则可以达到50Mbyte/s。
cFosBC是为了在低CPU占用率下实现最大吞吐量。这可以让你的CPU占用率达到实际的互联网应用，如媒体播放器等。在满速状态下，cFosBC的CPU占用率只需要3%。
cFosBC支持所有重要的PPPoE协议参数。这些可以很容易地与电话号码配置，用于拨号连接。由于cFosBC具有自动监测功能，它可以找到互联网上所有与你系统相连的接入点。
cFosBC也可以接受来电。从而你可以设置自己的PPPoE服务器。这也让你能够自己用千兆以太网测试速度。
cFosBC允许多个PPPoE连接同时进行。你可以用任何流进和流出的连接。根据‘服务器名’和‘AC-姓名’参数，你可以限制连接到某些服务或接入点。
cFosBC支持Vista平台上的NDIS 6，从而提供更多的网络性能。
cFosBC和cFosSpeed是一个完美的组合。高性能数据传输+流量塑型，即最大带宽和最小响应时间。
更新日志：
! Dial paramers are now specified in a new and easier format: aidx=xserv=xh=0/1ac=xto=xtr=xprio=xvlan=x As before the first parameter before the first is ignored for compatibility. All parameters after the first now have names and can be specified in arbitrary order. 'aidx' is the adapter index as stored in the registry. 'serv' is the service_name string. 'h=0' disables use of host_unique tag, 1 enables it. 'ac' is the ac_name string, which can be used to limit the PPPoE negotiation to a certain AC. 'to' is the initial timeout (default 2000), 'tr' the numer of tries (default 3).
* cFosBC now supports VLAN tagging. By specifying 'prio=x' (value from 0-7, default disabled) you can set the VLAN packet priority. 'vlan=id' sets the VLAN ID. Both parameters are used in the dial string. If you specify VLAN parameters, cFosBC ignores all packets not for a given VLAN ID or without VLAN header. For incoming calls cFosBC switches to VLAN mode if the first negotiation packet contains a VLAN header.
+ Added additional way of allocation to relieve non-paged pool.
x Fixed a problem under Vista where you could only establish one connection.
x Fixed potentially serious bug in interlocked handling.
x Multi-language fixes.
x Fixed connect problem. Thanks to Ralf Gailus again.
x Fixed broken taskbar icons. Thanks to Ralf Gailus for testing.
x Fixed an initialisation problem under Vista. Thanks to Ralf Gailus for report.
