There were
corporate and public access networks long before TCP was set in stone
as a dominant protocol. Most F500 were interchanging on SNA into the
1990s. And access networks like Tymnet, etc to talk to others.
Yeah, but those were all tied to some vendor. TCP/IP was the first
wide spread networking stack that you could get from a pile of different
vendors, Sun, Dec, SGI, IBM's AIX, every kernel supported it. System V
was late to the party, Lachman bought the rights to Convergent's STREAMs
based TCP/IP stack and had a tidy business for a while selling that stack
to lots of places. It was an awful stack, I know because I ported it to
a super computer and then to SCO's UNIX. When Sun switched to a System
Vr4 kernel, they bought it in some crazy bad deal and tried to use it
in Solaris. That lead to the tcp latency benchmark in lmbench because
Oracle's clustered database ran like shit on Slowaris and I traced it
down to their distributed lock manager and then whittled that code
down to lat_tcp.c. Sun eventually dumped that stack and went with
Mentat's code and tuned that back up. Sun actually dumped the socket
code and went just with STREAMs interfaces but was forced to bring
back sockets. Socket's aren't great but they won and there is no
turning back.
TCP, coupled with the rise of UNIX and the free wheel
sharing of BSD
code, are what made the people to talk to.
BSD wasn't free until much later than TCP/IP. TCP/IP was developed in
the 1970's.
