So keep in mind I don't have an SP background. I have a client who has thi=
s idea of getting into the SP business and I'm trying to help them realize,=
realistically, what kind of undertaking this will be.
For a residential SP, what is a good reference for general guidelines on si=
zing. Such as, for 6,000 residential users, how bandwidth upstream would b=
e required to be fairly assured your phone will not be blowing up with comp=
laints? What amount of oversubscription is acceptable at what amount of ba=
ndwidth? Are customers just sold if you tell them 5 meg down, even though =
you have a 20:1 oversubscription?
I have read in NANOG archives 100Mbps/1,000 users for a school campus envir=
onment; would residential be equivalent?
Any input would be greatly appreciated.
