By default, uunet seems to list all connections to paying
customers as DEMAND. While this may be correct in some
cases, it's far from correct for most sites I know. I'd
guess something like EVENING listed as a terminal link
would be much closer to an accurate cost, if not POLLED
or DAILY.
Beyond leading to some screwy paths generated by pathalias,
this can lead to increased costs for anybody who doesn't
catch it and ask uunet to change their map entry, or worse,
for folks who don't have the slightest idea what's going
on. This almost seems to border on being unethical.
Can anybody explain/justify this practice?
(I'm not trying to flame uunet or anybody else, though I
don't particularly like having to tinker with my local
pathalias input every time somebody nearby connects to
uunet and suddenly all my paths go thru joe!uunet.)

DEMAND indicates a high quality, reliable path through which the receiving site wants to receive a lot of traffic. By default, uunet sites are marked as DEMAND. They are ALL told this and offered the chance to change it.

If you have pathalias, do some runs with different costs for uunet in your site's map entry. We found that if we set the cost to EVENING, pathalias would generate a route through four machines to get to uunet, instead of going direct, because it could find a route to a site listed with uunet as DEMAND and it was cheaper by pathalias' criteria. This largely defeats the purpose and I don't think imsl wants to pay for our uunet traffic. Thus, if everyone lists the costs the same for uunet, the "closest" machine to you should be the one that calls uunet, and any site that has a uunet connection will get their stuff routed through it. -- -- uunet!ficc!karl "The greatest dangers to liberty lurk in insidious -- karl@ficc.uu.net encroachment by men of zeal, well-meaning but without understanding." -- Justice Louis O.
