Two more Protocols

We have now introduced two more protocols from Level 3 Internet Connectivity.

SLIP

• SLIP is hot-rod, bare bones encapsulation protocol
• Can be traced to TCP/IP implementations of the early 80s
• Is used to frame IP (Internet Protocol) packets for transmission over serial lines
• Makes no effort to minimize or compress the number of bytes sent across a serial line
• Simpler than PPP yet not as efficient

PPP

• Designed by committee, PPP is ``everything and the kitchen sink''
• Allows the transmission of multi-protocol packets over a single link (e.g. TCP/IP, DECnet, Appletalk)
• Has built in error correction
• More complex than SLIP.
