Abstract Cloud services are spreading among both individual and business customers. Though cloud providers declare very good performance indicators, their claims are often unsupported by a proper monitoring mechanism. QoS auditing for services provided on the cloud is therefore strongly needed. In this tutorial, we deal with the problem of correctly assessing the performance of cloud providers and identifying possible mechanisms to protect against QoS violations. We first review the most relevant critical issues in the estimation of performance parameters, and focus on the accurate estimation of availability in the cloud storage service. We then examine what can be envisaged when the cloud provider does not comply with its QoS commitments. In particular, we review insurance schemes that the cloud provider may employ to hedge against massive QoS violations and subsequent compensation requests.
Bio Maurizio Naldi is an Associate Professor of Computer Science at the University of Rome Tor Vergata. He holds a MSc degree magna cum laude in Electronic Engineering and a PhD in Telecommunications Engineering.

Ioannis Tomkos Athens Information Technology / Excellence Chair at U. Carlos III of Madrid 2018
Abstract We will discuss how the appropriate addition of Space Division Multiplexing (SDM) to the capabilities of conventional spectrally-flexible elastic optical networking (EON) concepts creates the ultimate solution for enabling huge capacity scaling, while supporting efficient utilization of network resources and achieving reduction of the cost and power consumption per transmitted/processed bit.

Bio: "Dr. Ioannis Tomkos (B.Sc., M.Sc., Ph.D.), is with the Athens Information Technology Center (AIT), since Sep 2002. He was elected “2018 Chair of Excellence Professor” (Cátedras de Excelencia) at the University Carlos III (Madrid, Spain), “Adjunct Professor” at the College of Optical Sciences of University of Arizona (2013) and “Adjunct Research Fellow” at the ECE Department at University of Cyprus (2014). In the past, he was an Adjunct Faculty member at the Information Networking Institute of Carnegie-Mellon University, USA (2002 - 2010), senior scientist (1999 - 2002) at Corning Inc. USA and research fellow (1995 - 1999) at University of Athens, Greece. At AIT he founded and serves as the Head of the “High Speed Networks and Optical Communication (NOC)” group that was/is involved in over 20 EU funded research projects (top performer over the past decade in EU funded projects on the topic of optical communications and networks), as well as in national and industry funded projects. In all of these projects Dr. Tomkos is representing AIT as Principal Investigator and had/has a consortium-wide leading role. Dr. Tomkos has received in 2007 the prestigious title of “Distinguished Lecturer” of IEEE Communications Society for the topic of “transparent optical networking”. Together with his colleagues and students he has authored over 600 peer-reviewed archival articles (including over 390 IEEE sponsored items that may be found through IEEE Xplore). His work has been received over 7750 citations (increasing currently with a rate of about 1000 per year) and his h-factor is 42 (as of Oct’17). He is included in the "Top H-Index" list of "Guide2Research" for the fields of "Computer Science & Electronics". For his research work he has been awarded several times (most notably with the “2014 IEEE/OSA Journal of Lightwave Technology Best Paper Award” and the “2001 Corning Outstanding Publication Award”). Dr. Tomkos has served as Chairman of the
International Optical Networking Technical Committee of IEEE Communications Society (2007-2008), Chairman of the International IFIP working group on “Photonic Networking” (2008-2009), Chairman of the International OSA Technical Group on Optical Communications (2009-2012) and Chairman of the IEEE Photonics Society Greek Chapter (2010-2013). Currently he serves on the Strategic Planning Committee of IEEE Communications Society. He has been General Chair, Technical Program Chair, Subcommittee Chair, Symposium Chair or/and member of the steering/organizing committees for the major conferences (e.g. OFC, ECOC, IEEE GlobeCom, IEEE ICC, ICTON, ONDM, BroadNets, etc.) in the area of telecommunications/networking (more than 150 conferences/workshops).

Abstract Recent advances in new technologies jointly with the appearance of low
cost sensors with computing and communication capacities have made
possible to implement new systems to improve citizens daylife. This
speech will review recent developments of Internet f Things and Wireless
Sensor Networks to gather data from urban environments and which
network protocols, algorithms and architectures have been designed and
developed to provide the most updated data. The knowledge acquired by
these sensors can be tackled in order to improve the electric
consumption, the water wastage and even any type of lakes in gas,
electricity or water. Big data and artificial intelligence techniques
can be used to optimize the resources of the cities and improve their
performance. The talk will explain several examples and show real
