PPP Components: Layered Architecture and Frame Structure Explained

A layered architecture is a logical model that helps different parts of a communication system work together. PPP’s layered model maps reasonably well onto the OSI model: both share the same physical layer, though PPP distributes the work of its Link Control Protocol (LCP) and Network Control Protocol (NCP) differently than OSI’s strict layer boundaries....
