Network Control Protocol

The Protocol NCP ( Network Control Protocol ) is a component of the Point -to-Point Protocol (PPP ) and is used for negotiating options between both ends of a point-to- point connection. These are therefore control protocols (Network Layer, also: packet-level or network layer ) between authentication and network network layer protocols are to be classified in the OSI model.

The various Network Control Protocols of 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: which put primary network protocol on the PPP protocol. The abbreviation NCP is also used as a Network Control Program in IBM SNA architecture, and since 1969 as a Network Control Protocol or Network Control Program in the ARPANET.

Originally developed in 1969 for the middle layers of the ARPANET Network Control Protocol (NCP ). It is thus as the predecessor of TCP / IP, which was developed by the Defense Advanced Research Projects Agency and the Network Control Protocol replaced in 1983.
