PPP Background Information
The Point-to-Point Protocol (PPP) encompasses a suite of protocols designed to provide
standard methods for transporting datagrams over point-to-point links. The use of PPP
over SONET links is commonly referred to as Packet over SONET, or PoS. The Extreme
Networks implementation of PPP for the PoS module provides support for the
following protocols in the PPP suite:
• Link Control Protocol (LCP)
• Link Quality Report (LQR) Protocol
