Then there's the interesting: "How do you classify 'to be dropped'

port-agile such as BitTorrent though. In theory that sounds like a grand
plan, in practice it isn't simple...


It really depends on the network.  Not all networks are the same.  Case
in point we have some network that carries a lot of video.  Obviously we
want all the channels to get from point A to point B, but there are
services that really can be classed as "best effort"; like the VOD

I think I didn't state my question clearly :( I get that if you know the
endpoints, or one side, or the protocol or the ports involved QOS isn't
'hard'. What my question really was getting at was Simon brought up the
normal QOS stuckee 'BitTorrent' (substitute any other p2p sharing
application which most folks claim is 'all illegal content anyway'). I was
wondering how QOS was supposed to work on that traffic, given it's
port/protocol agililty.

I suppose if you had some special traffic you could qos up that and down
everything else but that wasn't quite what Simon was getting at I don't
think.
