TCP/IP Protocol Suite

The job of the Internet Engineering Task Force (IETF) is to make the Internet work, and the IETF achieves that primarily by writing technical standards for network protocols. The TCP/IP Protocol Suite is a collection of protocols that ultimately enable us to share data across the Internet and other networks.

Search the Internet for information on one of the following IETF Request for Comments (try to pick one that has yet to be discussed on the message boards):

Discuss the primary function that makes the protocol unique from others. Describe the salient characteristics of the protocol including its relationship to the OSI Reference Model and discuss any security mechanisms that the protocol may have built into it. Write your own review of the prominent features of the protocol; do not include material directly copied from the associated IETF Request for Comments.
