My current network has a cable modem feeding an AEBS which then feeds 2 x 8 port dlink DGS-2208 8-PORT 10/100/1000 DESKTOP SWITCH. I have all ports full, mostly with low bandwidth use, and I have 2-3 wireless devices running through a wireless network of 2 AEBS and 1 Airport unit extending. My main problem: I am trying to do off-site backup via mozy, frequently 5-10GB at a time, which can take days to upload. When that is running I don't really have any major problems with computer use (somewhat slow, but tolerable), but my son's Xbox360 will not perform at all online (I guess mozy is killing latency for upload). Therefore I have to run up and shut down mozy i he/we want to play. What I'm looking to do is give "priority" to certain ports - i.e. the xbox would get top priority and then the other computers and last the machine running mozy. I would like at least a 16 port switch and maybe 24, although I guess I could feed from the managed one to one of my current 8 port switches. I need something relatively easy to manage, and I would like to spend no more than $300-400. Thoughts?
