This may have changed a bit - but we used to use 2000 high speed = 100 meg of capacity. Based on 5000/800 ADSL or 8000/1000 cable modem profiles mainly...

You only need a few heavy users to skew things. But 400 at 4 Mbps would make me think that 20 to 30 Mbps would be sufficient. Frank -----Original Message----- From: sjk [mailto:s...@sleepycatz.com] Sent: Tuesday, August 11, 2009 7:11 PM To: nanog@nanog.org Subject: Residential BW Planning 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.
