Here's a very good paper on the Crossbow network virtualization and resource control which is available in OpenSolaris since 2009.06: Crossbow Virtual Wire: Network in a Box.
This paper even won the best paper award for Usenix LISA 2009. The blog of one of the authors is available here where he writes about the award and the BOF at Usenix Lisa 09.
Well worth a read if you don't know what crossbow is and can do, and if you do it's still worth a read.
