FYI - I made a small but architecturally important change to the opensolaris overview at http://www.opensolaris.org/os/project/crossbow/crossbow_overview.png The new figure better represents our current planned long-term architecture, which allows multiple rings to be assigned to services or protocols *through* a single VNIC, in this case VNIC1, instead of requiring separate VNICs per services or protocols. -- Nicolas Droux, Solaris Kernel Networking Sun Microsystems, Inc. http://blogs.sun.com/droux
