Graphic 22.214.171.124 PPP contains three main components: HDLC protocol for encapsulating datagrams over point-to-point links. Extensible Link Control Protocol (LCP) to establish, configure, and test the data link connection. Family of Network Control Protocols (NCPs) for establishing and configuring different network layer protocols. PPP allows the simultaneous use of multiple network layer protocols. Some of the more common NCPs are Internet Protocol Control Protocol, Appletalk Control Protocol, Novell IPX Control Protocol, Cisco Systems Control Protocol, SNA Control Protocol, and Compression Control Protocol.
Graphics 126.96.36.199 thru 2.2. PPP Architecture - Link Control Protocol Layer The LCP is the real working part of PPP. The LCP sits on top of the physical layer and has a role in establishing, configuring, and testing the data-link connection. The LCP establishes the point-to-point link. The LCP also negotiates and sets up control options on the WAN data link, which are handled by the NCPs. 2.3 PPP permits multiple network layer protocols to operate on the same communications link. For every network layer protocol used, PPP uses a separate NCP. For example, IP uses the IP Control Protocol (IPCP), and IPX uses the Novell IPX Control Protocol (IPXCP).
