Umm, yes assuming you meant the Confusian way, right?

I think they call that 'interesting times' ;)      On 12/07/11 21:27, H Vlems wrote:
Remember what I wrote: this happened nearly two decades ago.
IP is the protocol that survived and most people aren   t even aware what happened on local area networks before, say,1998.
I worked for Fuji, photosensitive films, paper and offset printing products.
Most of the IT equipment was made by DEC: PDP-11   s (/44, /84, /93, /24, /73 and /23), VAXes, an IBM mainframe (4081) and PC   s.
And lots of other gear, most of it in the research lab. A Motorola box that ran Motorola Unix, and an RS/6000 under AIX 2.4 (?).
The lingua franca was DECnet and LAT. No IP, though some PC   s used Novell and SNA over tokenring to make terminal emulation to the mainframe possible.
No IP.   Sounds weird in today   s world but DECnet eventually connected everything. We got a *very* early Cisco router that did level 1
DECnet routing between the corporate ethernet and the finance dept token ring. Another (DEC) box that routed DECnet over Datanet/1 (that   s X25 in Europe IIRC). The mainframe used an SNA/DECnet gateway (the big channel attached box).
The RS/6000 and the Motorola systems also ran DECnet, endnode only.
To make this a little interesting we ran the first FDDI network in the Netherlands.
Trouble shooting wasn   t always easy, especially if the SNA/DECnet gateway was involved!
