But I've recently hit an interesting issue -- Microsoft (and/or akamai, or whatever) has recently started pushing updates to the xbox via ipv6 instead of v4. As I'm sure you know ipv6 addresses are essentially random on the internal LAN as compared to v4 -- a box can grab as many v6 addresses as it wants, and I don't believe my linux router can really know which box is using which address, can it? Which means... ipv6 breaks cake's flow isolation. Cake can't throttle all those xbox downloads correctly cuz it doesn't know they're all going to/from that one device. So I suppose this may be similar to the "bittorrent" problem -- which, is there a general solution for that problem? In my case the xbox grabs more than its share of bandwidth, which means other bulk streaming -- that is to say, youtube and netflix :) -- stops working well I can think of one general solution -- run more wires to more devices, and give devices their own VLAN, and tag / prioritize / deprioritize specific traffic that way... But.. are there better / more general solutions? Thanks, Dan
