-
- From my copy of the System V Release 4 "Programmer's Guide: Networking
- Interfaces" document:
-
- ...
-
- As part of the unification of UNIX System V and Berkeley UNIX,
- the sockets interface and support for the DARPA protocols (the
- TCP/IP Internet Package) ahve also been added to System V
- Release 4.0.
-
- Both TLI and sockets provide a programming interace to the
- transport layer. In System V Release 4.0, both are implemented
- within the STREAMS framework. They differ in the following
- ways:
-
- + TLI is media- and protocol-independent. It allows
- applications to run over any transport protocol that
- supports the TLI interface.
-
- + The sockets interface has historically been tied to the
- Internet protocol suite, TCP/IP and UDP/IP.
-
- It is expected that new applications will take advantage of
- TLI's protocol independence and that the socket interface will
- be used primarily in expanding and maintaining existing
- sockets-based applications.
-
- ("Berkeley UNIX"? Uh-oh, I think USL's lawyers had better sue the
- authors of the UNIX(R) System V Release 4 Programmer's Guide: Networking
- Interfaces; it appears to have come from the UNIX Software Operation of
- the American Telephone and Telegraph Corporation. Hmm. "UNIX Software
- Operation". Sounds a bit like "UNIX Systems Laboratory"....)

-
- Probably not. I don't see the sockets interface in SVR4 going away any
- time soon. Heck, if the POSIX 1003.n committee dealing with network
- interfaces does what I've heard they're considering doing, namely
- standardizing *both* a sockets *and* a TLI/XTI interface, they may be
- with us for a while. In addition, I think there'll be a sockets
- interface, at least to the Internet protocols, in Windows as well; I
- think many DOS Internet protocol implementations have a sockets-like
- interface.
