Download estimate tool?
by Brennan_Murphy＠NAI.com 01 May '02

01 May '02

I'm looking for a tool to estimate file download times given a certain set of variables: file size, available bandwidth, latency, receive window and circuit utilization. To explain: Suppose I have a single OC3 serving FTP downloads to individuals all over the globe. If the OC3 is not heavily utilized *and* I know the bandwidth and latency between my FTP server and a client's workstation, I can make a rough estimate of how long it will take for a file of a particular size to download. I could create a matrix in Excel based on latencies and bandwidths (factoring in TCP receive window sizes) and that would give me a quick reference tool for gauging how long something should take to download given a fair number of scenarios. But what if I want to enhance such a matrix to factor in what happens to download times in those various scenarios as the utilization of that OC3 approaches 100%? I could make alot of edits to above mentioned Excel matrix....but that would get tricky and visually unappealing. Can anyone recommend a tool that makes it easy to play with the above variables...a sort of modeling tool not quite so fancy or expensive as Opnet for example? Maybe a webpage with a Java applet ? Or maybe a fancy Excel file? Thanks, BM

| is it urban all the way to the falls now? ignoring the twin suburban horrors of missisauga and oakville, yeah. the golden horseshoe is really amazing in nighttime orbital shots, by the way. i think you should force the next government to pave the lake right to the border just to complete the | i usually head north from toronto (well, north-east). blackflies? politicians? d'you have a thing for evil blood sucking scum? oh wait, nortel is up there... Sean. ps i am told there is a reasonable food court at the nanog hotel, but calling it toronto is still kinda weird. northern ontario begins at st. clair.

| about half of that is city, and the other half vineyards and country. Vineyards along the QEW? Wow, when was the last time you ventured out of down town (Pearson doesn't count)? Sean. (Richmond Hell is in Nunavut, right?)

i think the hydrofoil is probaly just to niagara-on-the-lake, which is a charming but much-too-english town in which one can buy the best jams in the known universe, and very decent fudge. niagara falls is considerably further inland (and moving further...). the hydrofoil is fun, but bring a seasick bag, and a windbreaker.

Teleglobe and Equant Experiences?
by Crist J. Clark 30 Apr '02

30 Apr '02

I am currently evaluating some proposals from several vendors for an international IP-based network. Most of the technologies are the same, MLPS, and they can list routers brands and models, as well as give out network reliability and SLA numbers, so there is something to go on for technical matters. However, for the ones that I'm not too familiar with, it's really hard to guage things like customer service, billing, and their technical support responsiveness. The two providers who I've not had a lot of luck researching elsewhere are BCE Teleglobe and Equant. Does anyone have some opinions they'd like to share? Feel free to email me directly if you do not want to clog up the list or don't feel comfortable making certain remarks public. Thanks a lot. -- Crist J.
