MC-MLPPP Analyzer And Emulator
The Point-to-point protocol (PPP) is a link layer protocol, which encapsulates other network layer protocols like IP for transmission on synchronous (like T1/E1) and asynchronous communications lines. When transmitted over T1/E1 line, PPP frames are based on HDLC frame structure. Two major features of PPP protocol are:
*Authentication
*Encapsulation of higher layer protocols
