I am thinking of colocating a PEdge 1650 at a NOC, they provide fully burstable bwidth all the way up to 100s of Mbps. They measure every 30 minutes and take an average for that chunk. If any 3 averages in a month are over my plan (probably 512kbps) they will charge me extra.
My concern is some of my clients have 1Mbps connections and will be FTPing a lot of files etc and some sites will contain streaming media. This could easily mean on some occasions i will go over my limit putting my bandwidth costs through the roof.
so the question is, Can i cap off bandwidth via my NIC or something else per user connection? Also what are peoples experiences paying for percentile bandwidth? Will this be a bad move? should i look for a NOC that will charge for transfer rather than width?
