I wish there were. If anyone knows.. PLEASE POST IT.

Up until now I've been searching the web based on application and service.
Each appliation/process/task is going to take a different amount of bandwidth. It just depends on what has to be transfered and how many times (transmission failures, etc.)

For example.
Say we both have an as400. We both have clients connecting via remote sites over a WAN.
If I only have 10 users needing constant access and you have 25 users needing access, you are going to need more bandwidth than I will. Especially when I'm only using it 25% of the time you are. But that should be obvious?
