G-Lab

Studies- and Experimental Facility for the Internet of the Future

Consortium: COMCON

Control and Management of Coexisting Networks

“Network Virtualization in G-Lab COMCON”

2 Network Virtualization in G-Lab COMCON / Dr. Wolfgang Kiess

ASP: application service provider (services for customers) VNO: virtual network operator (rents & runs virtual network) VNP: virtual network provider (combines PIP resources) PIP: physical infrastructure provider (owns hardware)

Interaction between roles in virtual networks

I want to interconnect these customers

I need such a network structure for this

For this structure, I rent resources from these PIPs

To realize these virtual resources, I embed them like this in my physical network

Resource description

To negotiate and describe what is needed, we need a resource description language

� Resource description language has to support �  Information hiding �  Support for abstraction �  Multi-domain capable �  Multi-layer network support

� Identified TMF SID, extended it for virtual resources � Definition of usage directives � Prototypic implementation of extended SID
