Point-to-Point Protocol (PPP)
HDLC
Error Detection
Identify Contents
A very simple protocol
2 Version : Original & Cisco Proprietary
Summary
Made up of LCP & NCP
LCP
Link establishments,authentication,error detection,multilink,load balancing
Purpose : transport L3 protocols over serial links
PPP operates at L2 of the OSI model
NCP
how to transport the L3 protocols
PPP Components (1 of 2)
Establish , Configure & Maintain a Connection
Authentication,Error,Detection,Multilink,Loop Detection,Link Termination
Link Control Protocol (LCP)
Intro
Data Link Layer Protocol
Layer 2 of OSI model
Used to encapsulate Layer 3 protocols for transmission accross serial links
Synchronous & Asynchronous Links
Open standard
HDLC > Cisco HDLC > PPP
support
Authentication
Erro detection & link Quality monitoring
Load balancing
PPP Components (2 of 2)
Determines how Layer 3 protocols will be transported
NCP is made up of many protocols,one for each L3 negotiation
IPCP (IP Control Protocol) is a NCP that is used to negotiate sending IP within PPP frames
Network Control Protocol (NCP)
