This paper describes several efforts to explore integrated approaches to resource virtualization in a metro-scale optical testbed dubbed BEN (Breakable Experimental Network) located in Research Triangle Park, NC. The first one is an extension of work done at Duke on the ORCA (Open Resource Control Architecture) framework. The effort between RENCI and Duke seeks to expand the scope ORCA to enable it to function as management plane for the network as well as edge resources, acting as a GENI management plane. The second describes an attempt to redefine the architecture of the protocol stack with important implications to network virtualization. This is done using the SILO (Services Integration controL and Optimization) framework being jointly developed at RENCI and NCSU.
