CNSM 2015 Distinguished Experts Panel

Service Quality in Virtualized Environments: Improvement or Deterioration?

Currently, network operators and service providers are keen to adopt SDN/NFV-based network virtualization models. These models allow for faster and easier deployment, configuration, and updating of network functions on one hand. On the other hand, they enable dynamic scaling of resources based on service requirements and traffic patterns and reduced time to market for services.

However, the question remains to be answered whether large-scale adoption of these virtualization models will have a positive or negative influence on the quality of offered services. As today 67% of all IP traffic is used for delivery of multimedia traffic and this share is predicted to grow to 80% in the near future, this question is very relevant!

It is also unclear whether network security solutions will be able to efficiently cope with large scale virtualized networks environments.

For this reason, we selected distinguished experts from industry and academia with large expertise in this area, who will provide us interesting insights!

The following topics -amongst others- will be discussed: how to offer quality guarantees for content delivery in virtualized environments?, how to monitor end-to-end performance when physical devices are virtualized, where to put content caches, is ICN still a valuable research topic in virtualized networks?, how to provide fault diagnosis and fast recovery in virtualized environments, how will security management evolve in virtualized environment? etc.

We expect lively discussions and count on all CNSM 2015 participants (PhD students and experienced researchers from industry and academia) to ask questions and share their viewpoints.

We very much look forward to this panel discussion!

Prosper Chemouil received the M.Sc. and Ph.D. degrees in control theory from École Centrale de Nantes, in 1976 and 1978, respectively. He is currently a research director at Orange Labs and his research interests are with the design and management of Future Networks and Technologies and their impact on network architecture, traffic engineer-ing and control, and perfor-mance and quality of service (QoS). He has served as board member, associate and guest editor of various Journals including IEEE Communications Magazine and IEEE Networks, and Annals of Telecommunications. As Board Member of the IEEE SDN Initiative, he has launched in 2015 the IEEE International Conference on Network Softwarization. Since 2007, he is also the Chairman of the steering committee of the International Teletraffic Congress. Nominated as French Senior Engineer of the Year in 1995, he has received several awards such as the Blondel Medal, the Ampère and the Salah Aidarous Awards. He is a Fellow of the IEEE and the Electrical and Electronical Society of France (SEE).


George Pavlou is Professor of Communication Networks in the Department of Electronic and Electrical Engineering, University College London, UK, since 2008, where he coordinates activities in network/service management and networking. Prior to that, he was for ten years (1998-2007) Professor of Communication and Information Systems in the Department of Electronic Engineering, University of Surrey, UK. His research interests focus on networking, network management and service engineering, including aspects such as traffic engineering, quality of service management, autonomic networking, information-centric networking and communications middleware. He has published extensively in these areas and has given invited keynote speeches and tutorials in major international conferences. He has also been instrumental in a number of collaborative research projects that produced significant results with real-world uptake and has contributed to standardization activities in ISO, ITU-T and the IETF. He was technical program chair of the 7th IFIP/IEEE Integrated Management Symposium (IM 2001) while in IM 2011 he received the Dan Stokesbury award for “distinguished technical contributions to the growth of the network management field”. He is currently editor of the Network and Service Management feature topic which is published twice a year in IEEE Communications.



Filip De Turck leads the network and service management research group at the Department of Information Technology of the Ghent University, Belgium and iMinds (Interdisciplinary Research Institute in Flanders). He (co-) authored over 450 peer reviewed papers and his research interests include telecommunication network and service management, and design of efficient virtualized network systems. In this research area, he is involved in several research projects with industry and academia, serves as the vice chair of the IEEE Technical Committee on Network Operations and Management (CNOM), chair of the Future Internet Cluster of the European Commission, and is on the TPC of many network and service management conferences and workshops and serves in the editorial board of several network and service management journals.
