- While it has "historically been tied to ... TCP/IP", it's not intrinsically
- tied to it, and was definitely designed with protocol and media
- independence in mind. In particular, the original BSD implementation
- supported three different domains: INET, XNS, and UNIX. I believe that
- BSD4.4 adds OSI support to sockets, and SunNet X.25 provides a socket
- interface to X.25 connections.
-
- From what I was able to tell from the Stevens book, TLI and sockets are
- very similar. The structure of a program that uses either will be almost
- the same -- you could almost write an automatic translator.
