Title: Network Awareness and Virtualization Meets Cloud

Cloud computing brings service providers new opportunities to improve their own opera¬tions and generate revenue from cloud services. Service providers have the advantage of controlling network and data center resources. However, it has been challenging so far to manage both types of resources in a cloud computing solution that can deliver a wide range of services from a single elastic environment. In addition, today’s cloud computing technologies provide suitable execution platforms for many transaction- or batch-oriented applications but are not suitable for many other types of applications. In particular, delivering tele¬communication services that are time-sensitive, media-based, mission-critical, or persistent (long-lived) is challenging.

Network virtualization and network-awareness are key enablers for a new type of cloud that supports a wider range of services at greater efficiency. These clouds are more distributed and diverse, allowing them to meet specialized requirements of performance-sensitive services. Intensive research is going on to virtualize network resources and create network-aware clouds that orchestrate distributed resources and deliver services effectively and in high quality.

Innovations arising from these concentrated efforts will enable service providers to leverage their greatest asset: the network and its carrier-grade attributes. Service providers can transform their operations to become more efficient and agile while reducing costs. It also puts them in a better position to increase revenue by meeting the growing demand for highly available cloud services with high end-to-end performance.


Dr. Volker Hilt is the head of Networked Services Research at Bell Labs/Alcatel-Lucent in Stuttgart, Germany. Dr. Hilt received his master's degree in Information Systems in 1996 and his Ph.D. in Computer Science in 2001 both from the University of Mannheim in Germany. He joined Bell Labs/Alcatel-Lucent in New Jersey, USA in 2002 and moved to Germany in 2012.

His field of research is computer networking where he has made contributions in the areas of cloud computing technologies, content distribution networks, peer-to-peer applications, distributed multimedia systems and the Session Initiation Protocol (SIP). Dr. Hilt is a leading contributor to the Internet Engineering Task Force (IETF) and chairs the SIP Overload Control Working Group and the Peer-to-Peer Research Group. He has published over 50 papers and co-authored more than 15 Internet drafts and RFCs.
