PPP NCP: Network Control Protocol in PPP
The Network Control Protocol (NCP), a protocol in the Point-to-Point Protocol (PPP) suite, provides services in the PPP link connection process to establish and configure different network-layer protocols such as IP, IPX or AppleTalk. After an NCP has reached the opened state, PPP will carry the corresponding network-layer protocol packets. Any supported network-layer protocol packets received when the corresponding NCP is not in the opened state must be silently discarded. The most commonly used NCPs are IP Control Protocol (IPCP) and IPv6CP.
