Network Control Protocol is uses to identify the Network layer protocol used in the packet
PPPis more secure than SLIP. PPP uses two authetication Protocols : 1. Password Authetication Protocol (PAP) 2. Challenge Handshake Authetication Protocol (CHAP) So if you use SLIP on network that unauthorized user can gain acces to.

Point-to-Point Protocol (PPP) is the most commonly used protocol for dial-up connections.
PPP is point to point protocol. It does single channel network links, usually over a long distance, or a VPN. The program that sets up and manages PPP connections is pppd.
Network control protocol
there may be the issue with the layer 2 protocol like hdlc or ppp is not configured or wrongly configured if the interface is serial interface.
LCP sets up the PPP connection and its parameters. NCP handles higher layer protocol configurations.
Point to Point Protocol (PPP) protocol is utilized to establish a connection betweenyour PC and your ISP (Internet Service Provider). PPP is used on two points-connection onlyusually modem to modem. This protocol accomplishes a few main tasks:Checks the condition of the phone line.Checks your password.Provides your computer with an IP address valid for the duration of connection.Establishes the configuration of packets (packet size, compression, etc).Acknowledge one part that the other is closing the connection.PPP operates by sending Request packets and waiting for Acknowledge packets that either accept, rejector try to change the request.Various protocols are utilized to accomplish different tasks which together form the PPP.
