Network Control Protocol
The protocol NCP (Network Control Protocol) is a component of the Point-to-Point Protocol (PPP) and is used for the negotiation options between both ends of a point-to-point connection. These are therefore control protocols between authentication and network protocols of the network layer (English Network Layer, also: package-level or network layer.) From the OSI model are classified.
The different network control protocols of the PPP are:
- IPCP (Internet Protocol Control Protocol) for the Internet Protocol IP
- IPV6CP (Internet Protocol Version 6 Control Protocol) for IPv6
- IPXCP (Internetwork Packet Exchange Control Protocol) for the Internet Packet Exchange Protocol
- ATCP (AppleTalk Control Protocol) for AppleTalk
The term Network Control Protocol (NCP) is used in different contexts, but not standardized: Primarily for network protocols which are based on the PPP protocol. The abbreviation NCP is also used as the Network Control Program in IBM's SNA architecture , and since 1969 as the Network Control Protocol or Network Control Program in the ARPANET .
The Network Control Protocol (NCP) was originally developed for the middle layers of the ARPANET from 1969 . It is therefore the predecessor of TCP / IP , which was developed by the Defense Advanced Research Projects Agency and replaced the Network Control Protocol in 1983.
