Reliable Resource Allocation for Network Function Virtualization

Network virtualization plays a key role in the next-generation networking paradigm with enabling multiple tenants to share the same physical infrastructure. By leveraging the technologies of software-defined networking and network function virtualization, a platform with network virtualization provides virtualized resources of networking, computing, and functionality to users in a cost-effective and dynamic manner. Network virtualization brings challenges for network management, one of which is how to efficiently allocate resources with satisfying different requirements. In addition, as the adaptation of network virtualization in different application archetypes is an increasing trend, the reliability of an environment with network virtualization has become a major concern. This tutorial addresses challenges of reliable resource allocation in network virtualization. It mainly consists of two parts. The first part describes basics about network virtualization by overviewing technology evolutions from traditional network/function to software-defined network/function and several issues on reliable resource allocation in network virtualization. The second part introduces several ongoing hot research topics including several types of protections, probabilistically guaranteeing protection, workload-dependent failure probability, mapping and scheduling of service function chains, and unavailability analysis of network functions.

HealthCare has been a major field for the application of the Internet of Things (IoT). In the last years, we have observed an increasing economic and technological development in the, so called, Internet of Health Things (IoHT) resulting from the popularization of the health-related devices and their interconnection. IoHT has a great potential to revolutionize medicine and healthcare, offering easy access to health-related data to users and healthcare professionals. Further, it improves remote healthcare monitoring and the development of new applications. However, the nature of IoHT devices and communication technologies makes security, privacy and resilience priorities for researchers worldwide. Also, the sensitivity of the addressed data and the criticality of the IoHT services attracts even more attention, not only from researchers, but equally from attackers. This tutorial will present an overview of IoHT and its issues related to security, privacy and resilience. It will reinforce the importance of IoT for healthcare, showcasing IoHT prominent applications, then it will show existing research on security, privacy and resilience in IoHT. The tutorial will point out experimental environments that can be employed as testbed and it will highlight future research directions.


Michele Nogueira is an Associate Professor in the Computer Science Department at Federal University of Minas Gerais (UFMG), Brazil. She received her doctorate in Computer Science from the University Pierre et Marie Curie – Sorbonne Université, France. She was on a sabbatical leave at Carnegie Mellon University, USA (2016-2017). Her research interests include wireless networks, security and dependability. She has worked on providing resilience to self-organized, cognitive and wireless networks by adaptive and opportunistic approaches. Dr. Nogueira was one of the pioneers in addressing survivability issues in self-organized wireless networks, being the work “A Survey of Survivability in Mobile Ad Hoc Networks”, one of her prominent scientific contributions. She has been a recipient of Academic Scholarships from Brazilian Government in her undergraduate and graduate years, and of international grants such as from the ACM SIGCOMM Geodiversity program. She served as Associate Technical Editor for the IEEE Communications Magazine. She serves as chair for the IEEE ComSoc Internet Technical Committee. She is an ACM and IEEE Senior Member.
