Packet Prioritization/QoS

I am looking for a reasonably affordable and reliable way to provide packet prioritization within my LAN, based on TCP/UDP port.

For example, I want VoIP traffic to flow through my network uninterrupted, without being squelched by somone copying a large file to the server.

I think this would be accomplished by a switch with special capabilities. I have been trying to figure out which brands/models will do this, but I can't make heads-or-tails out of "QoS", "802.1p", "Layer 2 switching" and the other technologies and standards available.

Ultimately, I am looking for a recomendation of a specific brand and model of device, but I would also like to know which technology does what I am asking, so I can make an informed decision.
