27 Aug 2009 Project Crossbow Enables New Levels of Virtualization in the Solaris Network Stack [22184]
Etherstubs Feature Simulates Complete Network Topologies

Thanks to Sun's Project Crossbow, which enables full virtualization of the Solaris network stack, network interface cards (NICs) can now be virtualized into one or more virtual NICs (VNICs). These VNICs can then be individually configured and tuned to take advantage of the physical NIC's in-hardware capabilities and workload needs. So writes Ben Rockwood in his article for Search DataCenter.com, "Solaris Project Crossbow Offers Virtualized Network Management."
