“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
