I am trying to perform some capacity planning for some of our residential pops, but the old calcs I used to use seem useless -- as they were adapted from the dialup days and relied upon a percentage of users online (~50%) and a percentage of concurrent transmission (~19%). My present scenario involves a micro-pop terminating 250 residences where users are expecting 4 mb/s. So I am looking for some baseline to begin at, so I am wondering what others are doing. Any thoughts are appreciated.
I've seen everything from ~20 kilobit/s/user at peak, to over 400 (measured at 5 minute average with mrtg with ~500 users).
It differs a lot if you get the "mom and pop"-userbase or if you have bunch of students who are downloading/streaming stuff all the time.
Generally, comparing ADSL 8/1 to ETTH 10/10 or 100/100, download doesn't differ much, but symmetric speed users put out factor 4 more traffic (8/1 users upload half as much as what they download, ETTH users upload double what they download).
