Someone syncs w/ bkbits every 19 seconds 24x7. We also run our web server here. All traffic to from bitmover.com/bitkeeper.com/bkbits.net goes through that T1 line. You guys who are saying it can work are thinking (a) one connection of long duration (think about all the web hits on bkbits.net, those are all short and new TCP connections) and (b) that a little settling time is OK. There is a reason that the phone networks don't work like IP networks. The bandwidth is allocated whether you use it or not and your phone works. Doing optimistic allocation and then backing off means that the phones don't work. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
