Mpd is a netgraph(4) based implementation of the multi-link PPP
protocol for FreeBSD. It is designed to be both fast and flexible.
It handles configuration and negotiation in user land, while routing
all data packets strictly in the kernel. It supports several of
the numerous PPP sub-protocols and extensions, such as:
Multi-link PPP capability
PAP, CHAP, and MS-CHAP authentication
PPP compression and encryption
Point-to-Point Tunnelling Protocol (PPTP)
Mpd also includes many additional features:
Dial-on-demand with idle timeout
Multiple active connections running simultaneously
Dynamic demand based link management (also known as ``rubber bandwidth'')
Powerful chat scripting language for asynchronous serial ports
Pre-tested chat scripts for automatic configuration of several
common modems and ISDN terminal adapters
Clean device-type independent design
Comprehensive logging
