Can you point me to some current network sizing advice for Internet service (WAN and LAN)? I am looking for rules-of-thumb, guidelines, equations, books, or even anecdotal evidence that would help me in evaluating future network design concepts. I have somewhat unconventional network constraints, but I would like to start from current conventional assumptions on, say, numbers of users (home or office) that can be supported by various bandwidths. I've tried the related links off the NANOG pages, but some are old or broken. I have found some advice like "a T1 will support 200 to 300 28K modem users," but I hope there may be more current advice somewhere especially with regard to QoS, future trends, and to larger networks. Any relevant pointers or advice would be welcome. R/ Dan Glover

There's are two very simple rules: - if you install it, they will use it - you can never have too much bandwidth More seriously, it really depends on what you're doing - an office full of graphic artists needs a lot more bandwidth than an office full of data entry clerks. ************************************************************************** The Center for Civic Networking PO Box 600618 Miles R.

It doesn't matter Napster is about to be dead and all those people will go back to using IRC to trade music.

I'm not sure which is more surreal, the 11th-hour proposal by Napster to filter based on filename "because nobody would ever misspell Metallica", or the interesting twist in Aimster's usage policy, which would require the record industry to intentionally violate the same laws they wanted passed in order to get evidence to use as the basis of a lawsuit....

Good point. When I wrote that, I hadn't had my coffee, yet. :-( There is the Hydra effect after all. cuirtis
