To all who use VMS & ultrix every day (include me),
Why hasn't DEC offered a fully-featureded DECnet for ultrix?
What I've heard:
(a) DEC: 'usually there is a VMS node around, so if you need
full routing capability, you can use it. If you need
full routing from your ultrix host, you have tc/ip' -
customer support in Mass, OCT '86.
(b) The VMS-only systems types say: 'unix can't pedal that fast,
since its not written in assembler, like VMS; So unix
*can't* support full routing DECnet'
My theories:
(a) unix was designed to support networking of any sort, where
VMS was not, so that the relative load of any given
networking scheme (e.g. DECnet) would more burden VMS
than unix.
(b) DEC seems to be displaying a poor commitment to its unix/ultrix
users by not offering full DECnet for ultrix - perhaps
a marketing decision was made to discourage ultrix use
by offering low-quality networking software, thus selling
more VMS ... perhaps making support easier, since you have
95% of resources (people) in one area, instead of two...
DEC offers many operating systems, so why is ultrix not
just another? (even RSX-11M+ has full DECnet (PDP-11), but
not ultrix-11 or ultrix-32)...
Configuration: 8650 Ultrix-32 V1.2 on ethernet/DECnet to local 3-node
VMS cluster, on CCnet (a DECnet with ~400 nodes).
What's a good guess as to the real reason?
How can I refute the opinion that 'unix can't pedal fast enough'
to support DECnet?
References to the literature would be appreciated, and I will
summarize my work and users' responses to the net.
