Thanks for the response Mike.
I know there are many variables so maybe I'm asking something that has no
real answer.
I'm trying to find what others "in the field" are doing to calculate
capacity. I work for a company that won't spend money until absolutely
necessary! We support several remote offices and buy companies and "improve"
their infrastructure. We can't go to the site, only ask questions about the
applications and users. So, we don't always have access to use a sniffer and
get the real utilization. That's why I'm trying to use "guidelines" for
calculations without measurements.
***So what I'm trying to determine... EXAMPLE
Say I have a 1Gig backbone...any guideline to how many 100mb or 10mb ports
can be supported on 1 segment without oversubscribing? Most users use
typical "Office type applications".
See my reference below to frame relay planning.
I have other examples but I won't bore you! Are there links out there? Good
books?
Any ideas?
Thanks,
Ken

What kind of answer are you looking for? There are soo many variables......
Are the 40%/70%, etc guidelines not enough? Help me out.....
