Introduction

Motivation

The Internet Protocol is designed for use in interconnected systems of packet-switched computer communication networks. Such a system has been called a “catenet” 1) Cerf, V., “The Catenet Model for Internetworking,” Information Processing Techniques Office, Defense Advanced Research Projects Agency, IEN 48, July 1978. . The internet protocol provides for transmitting blocks of data called datagrams from sources to destinations, where sources and destinations are hosts identified by fixed length addresses. The internet protocol also provides for fragmentation and reassembly of long datagrams, if necessary, for transmission through “small packet” networks.
