For example, the first Cisco 2501 router to roll off
the assembly
lines was
in 1994. And at least in the early days, the only
addressing they had
was
Novell IPX. neither igrp nor ospf were there yet.
(just putting
things in
perspective).
All right, let's review the history here.
cisco Systems[1] was incorporated in 1984 by Len Bosack and Sandy
Lerner, the
directors respectively of the Computer Science Department Computer
Facility and
the Graduate School of Business Computer Facility of Stanford
University; their
first two employees were Kirk Lougheed, systems manager for the
Electrical
Engineering Department Computer Facility, and Richard Troiano, a
programmer at
GSB.
What were their products? The MEIS (Massbus-Ethernet Interface
Subsystem), a
3Mbit Ethernet for the DECSYSTEM-20 (for which Digital would not produce
an
Ethernet until 1988), a TCP/IP router based on SUN-1 cards in a VME
chassis,
and a terminal interface processor (TIP) based on the same hardware.
Who were their target market? Anyone intending to build an internet
linking
two or more Ethernet-based local-area networks, a topology demonstrated
at
Xerox PARC (where Ethernet was invented) using another internetworking
protocol
suite called PUP (PARC Universal Packets).[2] They did this because
they saw a
time when the Internet would be available to any business, not just
those under
contract to the US Department of Defense or the US Department of Energy,
and
they wanted to be in place to take advantage of that with an already
deployed
technology.
So the capabilities of the 2501 (which, if I remember correctly,
originated as
a product from Catalyst, a smaller competitor which cisco bought out
around
1992 while I was working for them) are irrelevant to what cisco gear
could do
with respect to the Internet.
[1] The original spelling even had a leading apostrophe: 'cisco Systems.
The
first part of the name is an abbreviation of "San Francisco".
(Personal
communication from Sandy Lerner)
[2] In point of fact, the cisco router was capable of doing PUP as well
as
TCP/IP.
