Serial link internet protocol..............

For CSLISP, the TCP header is reduced from about 20 characters to about 7. The actual data is not compressed, so you don't save very much in transmission costs per packet.

DATA Transmission is done through SLIP (Serial Line Internet Protocol) & PPP (Point to Point Protocol) Protocols to enable computers to interact with Internet over Telephone Line.

It is a very simple protocol used for transmission of IP datagrams across a serial line.

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.
