Informative document about Project Crossbow for Network virtualization in solaris

Found yesterday a link in BigAdmin about an informative document with examples for the
project Crossbow developed in OpenSolaris , which virtualizes the network interface ( NIC ), with software routers and so on.
It contains a lot of command line examples how to use it.
Flowcontrol about Ressource and bandwith control is also a little bit covered.

It contains also an example about connecting multiple networks in a T2000 system via zones.
Here is the link for the PDF document.
