- Happy holidays LAN gurus! I am looking for reference books on the
- actual ethernet, token-ring, and FDDI formulas to perform some
- bandwidth calculations for a site.
-
- I have looked at Bartee's "Data Communication, Networks, and Systems", Martin's
- "Local Area Networks", and a couple of others but they do not go into the
- details I require. I am not afraid of perform some intregation (Calculus work).so any formula in this level of detail is fine.
-
- What I am trying to do is calculate the minimum bandwidth requirements of
- a backbone network based on several 10BaseT ethernet concentrators. I do
- know the number of workstations to be attached to this LAN and the average
- load of a given time based on the number of workstations to be installed.
- The 10BaseT concentrators will attach to the backbone network, where all
- the servers will reside. My objective is to determine the type of backbone
- required to handle the expected level of traffic from the workstations via
- 10BaseT concentrators -- the backbone can be either ethernet, token-ring, or
- FDDI.
-
- The purpose is to justify the type of backbone recommended based on
- mathematical models (based on certain assumptions).
-
- Any ideas? Thanks. --GIF
