Hi Chris, I disagree with your "start with the least amount you can get away with" approach. The delay time between ordering and the installation of upgrades can be painfully long, especially when users and your boss asks "Why?". Also, it doesn't help your reputation, if you keep asking for more money to "fix" (upgrade) the "problem" (equipment). And it can end up cost more $$$ in the long run, due to installation charges, etc. I would estimate the total bandwidth needed, lease the equipment - signing the shortest lease possible (preferably one year) and re-evaluate your bandwidth needs after six months. Users have a way of chewing up bandwidth. And the last thing your boss wants to hear is that there is a problem. Do you remember Murphy's Law? Thomas' Law states, "Murphy was an optimist!" <G> Just my $0.02 Terry Chris Bipes <chris.bipes@cross- To: "'MIDRANGE-L@midrange.com'" check.com> <MIDRANGE-L@midrange.com> Sent by: cc: owner-midrange-l@mi Subject: RE: Frame Relay - How much bandwidth is drange.com enough? 01/16/01 01:17 PM Please respond to MIDRANGE-L If you are not sure, start with the least amount you can get away with. If you are serving up web pages with heavy graphics to business customers you will need more. If you are doing transaction processing you don't need much. BUT you do want to get a CSU/DSU and Router that can handle up to a full T1. Most routers today have built in CSU/DSU that can handle fractional T1. We have a full T1 for our web serving and web based transaction processing. We have a private WAN running 128k with several business partners doing FTP and real time transaction processing. Our bandwidth runs about 1 to 2 percent with burst to 90 percent during FTP. How do you know if you have enough? Buy the min you can with upgradeable hardware and contract. Monitor your utilization and add more as needed. If they are only doing 5250 emulation, 56k can handle 10 to 15 users easily. Christopher K.

I am currently tasked with setting up a sister company so they can run off of our AS/400. We are leaning toward frame relay and my first (probably of many) question is this. Are there any rules of thumb or tools that help determine how much bandwidth is enough? All the vendors obviously want to sell you as much as they can and we don't want to "over" buy. Also, has anyone had good luck/experiences with a particular vendor, or more importantly bad luck/experience? Thanks in advance.
