Overview
Chapter 19, you were introduced to TCP/IP, a robust set of protocols designed to provide communications among systems with different operating systems and hardware. The TCP/IP protocols were developed in the 1970s as a special DARPA project to enhance communications between universities and research centers. These protocols were originally developed on Unix systems, with much of the research carried out at the University of California, Berkeley. Linux, as a version of Unix, benefits from much of this original focus on Unix. Currently, the TCP/IP protocol development is managed by the Internet Engineering Task Force (IETF), which, in turn, is supervised by the Internet Society (ISOC). The ISOC oversees several groups responsible for different areas of Internet development, such as the Internet Assigned Numbers Authority (IANA), which is responsible for Internet addressing (see Table 38-1). Over the years, TCP/IP protocol standards and documentation have been issued in the form of Request for Comments (RFC) documents. Check the most recent ones for current developments at the IETF Web site at www.ietf.org.
