Model of Operation

Model of Operation The next several reading selections come from RFC 791, IP's Protocol Specification.

Remember that IP's primary task is the delivery of data packets from one location to another.


The model of operation for transmitting a datagram from one application program to another is illustrated by the following scenario:

                                    
   Application                                           Application
   Program                                                   Program
         \                                                   /      
       Internet Module      Internet Module      Internet Module    
             \                 /       \                /           
             LNI-1          LNI-1      LNI-2         LNI-2          
                \           /             \          /              
               Local Network 1           Local Network 2
