Solaris PPP is an asynchronous implementation of the standard data-link level Point-to-Point Protocol (PPP) included in the TCP/IP protocol suite and provided by a number of router system vendors and terminal concentrators. It includes a standard encapsulation protocol, making datagram transmission transparent to network layer protocols.
The major characteristics of the Solaris PPP protocol are:
Implements the Internet Point-to-Point Protocol, as defined in RFC 1331
Provides error detection through CRC
Supports full duplex transmission
The major functions of the protocol are:
Interface for IP to forward packets over asynchronous serial lines
Connection establishment on demand
Configurable options negotiation
Connection termination (automatic hang-up)
