The former is sometimes called "Berkeley sockets," indicating where it was originally developed. The latter, originally developed by AT&T, is sometimes called XTI (X/Open Transport Interface), recognizing the work done by X/Open, an international group of computer vendors that produce their own set of standards. XTI is effectively a superset of TLI. This text is not a programming text, but occasional reference is made to features of TCP/IP that we look at, and whether that feature is provided by the most popular API (sockets) or not. All the programming details for both sockets and TLI are available in [Stevens 1990]. 1.16 Test Network file:///D|/Documents%20and%20Settings/bigini/Docu...homenet2run/tcpip/tcp-ip-illustrated/introduc.htm (17 of 20) [12/09/2001 14.46.31] Chapter 1. Introduction Figure 1.11 shows the test network that is used for all the examples in the text. This figure is also duplicated on the inside front cover for easy reference while reading the book. Figure 1.11 Test network used for all the examples in the text. All IP addresses begin with 140.252. Most of the examples are run on the lower four systems in this figure (the author's subnet). All the IP addresses in this figure belong to the class B network ID 140.252. All the hostnames belong to the .tuc.noao.edu domain.(noao stands for "National Optical Astronomy Observatories" and tuc stands for Tucson.) For example, the lower right system has a complete hostname of svr4.tuc.noao.edu and an IP address of 140.252.13.34. The notation at the top of each box is the operating system running on that system. This collection of systems and networks provides hosts...
