2.1. Relation to Other Protocols

2.1. Relation to Other Protocols

The following diagram illustrates the place of the internet protocol in the protocol hierarchy:

                                    
     +------+ +-----+ +-----+     +-----+  
     |Telnet| | FTP | | TFTP| ... | ... |  
     +------+ +-----+ +-----+     +-----+  
           |   |         |           |     
          +-----+     +-----+     +-----+  
          | TCP |     | UDP | ... | ... |  
          +-----+     +-----+     +-----+  
             |           |           |     
          +--------------------------+----+
          |    Internet Protocol & ICMP   |
          +--------------------------+----+
                         |                 
            +---------------------------+  
            |   Local Network Protocol  |  
            +---------------------------+  

             Protocol Relationships

                   Figure 1.

Internet protocol interfaces on one side to the higher level host-to-host protocols and on the other side to the local network protocol. In this context a "local network" may be a small network in a building or a large network such as the ARPANET.
