[HECnet] HECnet routing costs

[Johnny Billquist]

People, I have written a page about DECnet costs and HECnet costs, which 
I would recommend that anyone interested read through. It contains a bit 
of elaboration on how DECnet does routing, and gives some suggestions on 
how costs could be set on HECnet to make it perform better.

I have noticed over the years that sometimes we do get really silly 
routing decisions just because of how people set, or do not set costs. 
The page I've written is by no means perfect, nor are the suggestions in 
there. But feel free to come with feedback, or ignore it. But I am going 
to try and use this myself more properly from now on, and that means 
that if others don't, you probably are going to get more traffic through 
your nodes. Traffic that probably do not make sense that it passes 
through you, but I just feel that I prefer to try and make it work right 
from my point of view, and then just at least tell people how I worked 
my numbers out. If someone have a different idea, I'm open to changing 
my settings, but I will not try and do optimizations to achieve:
a) Same paths for packets in both directions - DECnet explicitly does 
not do this.
b) Specifically penalize one type of interface because of any subjective 
preference about that type of interface in general.

Oh - and the link to my writeup: http://mim.update.uu.se/costs.htm
