Link Access Procedure (LAP ): LAP protocols are simply data link layer protocols which are needed for data framing and transmission of data over the P2P links. LCP is simply PPP protocol that is used for transferring of data frames into different areas like as establishing of connection, testing, and maintenance. Link Control Protocol (LCP): LCP protocol was introduced by IEEE 802.2.2, and its main role is to deliver HDCL style services over Local Area Network. NCP is mostly used for negotiating network-layer protocols. LCP protocol is used for bringing line up negotiation of options as well as bringing them down. It is supported to error detection system, and it also produces 2 protocols like as LCP and NCP. This is a simply byte oriented protocol that is mostly used for broadband communications which have massive load and higher speed. Point to Point Protocol (PPP): PPP protocol is used where to need transfer multiprotocol data in between two different directly linked computer systems. It is not supported to error correction and detection mechanism.

Serial Line Interface Protocol (SLIP): SLIP is a simply protocol that is added with framing byte at the end of IP packet, and it was designed for transmitting data unit in between the Internet service provider as well as home network users based over the dial up connection. This is bit oriented protocol that is accepted for both communications like as point to point and multipoint. It is based on SDLC and delivers both reliable and unreliable services. High Level Data Link Protocol (HDLC): HDLC protocol was introduced by ISO in 1979, and it is adopted like as associated part of X.25 network system. Main role of SDLC protocol is to ensure that all data units must be arrived appropriately and with correct flow from one network unit to further network unit. SDLC protocol helps to attach remotely devices with mainframe computers at centralized point may be point to point otherwise point to multi point connections. Synchronous Data Link Protocol (SDLC) : This protocol was introduced by IBM in 1970, and it is associated part of Systems Network Architecture. You can say examples of those protocols below explain each one – Network Control Protocol (NCP) Data Link Layer Examples of Protocols.
