This is what I have been mentioning in my last few posts but not many have been catching on. The real danger here is if you have say a dozen or so people trying to push more traffic then the ubr can cope with whats going to happen to live applications that are dependant on latency it is in real danger of been sporadic and going through the roof. Ideally shaping needs to be done that favours udp/icmp and small tcp packets over large tcp packets.

Download speeds I would expect to be very variable rather then the flat speeds we tend to see now you might be downloading a 200meg file and it maxes at 10mbit for a few secs but at some other point of the download it might drop to say 300kbit, I think we will be seeing a lot of this sort of stuff happening.

The problem here is it isnt time of day based so whats stopping everyone using 30gig a month only during peak time periods and bringing the ubr to a standstill?
