Re: ISPs can't win! The problem with set it and forget it, is that life does not work that way. Take weekdays from 9am-3pm during the school year, most systems are under a fairly light load. Now throw in a snow storm or any other event that closes school. Now suddenly the system is flooded at a time that it would normally be idling along. College usage is the same way. The week of and before exams everyone is hammering the books, the week after everyone is hammering the net. Life just does not follow a schedule.
The 90% was just a first guess. You would need a number that would always allow the stray individual checking the weather radar to be able to do so at a reasonable response time. But that "reserved overhead" (for lack of a better name), should be relatively small. Lets assume Docsis 1.0. If it is set at the 90% level then there would still be 4Mbs (38*.10) of bandwidth left over for our insomniac to check the weather. If he stays up longer (uses more bandwidth) the float would be cranked down (I think I suggested that it would be reevaluated every 15minutes). The 90% and 15 minute numbers would need to be dialed in to determine what fit the best.
I do not think that asymmetry is the source of the bandwidth crisis (I do not think there is a bandwidth crisis to start with). Most (certainly not all) people are more concerned with download speed anyway. While having no upload capacity to ask for the next whatever can be an issue it is a relatively rare thing. |
