Experimental Demonstration of Network Virtualization and Resource Flexibility in the COMCON Project

In the recent past, Network Virtualization (NV) received much attention. Nevertheless, Virtual Networks (VNs) are still not available on the market. The consortium of the COntrol and Management of COexisting Networks (COMCON) project examines the potential interactions in vertically and horizontally divided markets and evaluates the applicability of existing technologies, like Generalized Multi-Protocol Label Switching (GMPLS), for automated virtualization-enabled network management. To promote the manifold research, a selected scenario was demonstrated at the EuroView 2011 comprising a Video on Demand (VoD) service using a Scalable Video Codec (SVC). All necessary components have been implemented and the selected scenario was performed on a real network based on Linux PCs. In this paper, we describe the components, the scenario, and the gained insights in detail.
