Dennis, this sounds like an overstatement. Fair does not necessarily mean 'all equals', there can be different weights for different users depending on how much they pay for, and the fairness is in making everyone get what he pays for. Hard limiting the bw for each user as you seem to suggest prevents eveyone from taking advantage of statistical multiplexing, which, given the burstiness of network traffic, is very rewarding for all. (well this is the "isp" not "hackers" so excuse me if I don't stick with what existing products do ... ) Cheers Luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________
