Keynote Title: "Routing: from a Structured World to the Unpredictability of Wireless"
Abstract: Routing is playing a key role in the Internet and has evolved to support new types of applications and services, as well as network structures. This talk addresses the way research into routing has been conducted in the last 20 years. The main routing objectives are set out together with a discussion of the challenges facing the design of routing solutions. Wired networks have been, and still are, the core building blocks of the Internet. These are only possible owing to the capabilities of routing protocols to provide end-to-end connectivity across multiple domains. There will thus be an examination of routing solutions for wired networks, including aspects such as quality of service routing, traffic engineering and signalling. Routing in multi-hop wireless networks raises new challenges because of the characteristics of the wireless medium and its potential node mobility. These will be investigated for three different types of multi-hop wireless networks, namely, Wireless Mesh Networks, Mobile Ad-hoc Networks and Delay Tolerant Networks. There will also be an analysis of current research involving routing problems namely, in Machine-to-Machine communications, Cloud-based Internet of Things systems, and Cloud infrastructures. The work presented in this talk summarises several years of research at the Laboratory of Communications and Telematics (LCT) of the Centre for Informatics and Systems of the University of Coimbra (CISUC) including results obtained in national and international projects and lays out topics for open issues in this research area.

Keynote Title: "Designing Reliable Virtual Networks: Challenges and Solutions"
Abstract: Network Virtualization allows multiple Virtual Networks to coexist on a single physical substrate in isolation from each other, i.e., without security or performance interferences. It has been propounded as a diversifying attribute of the future inter-networking paradigm that can enable seamless integration of new features resulting in a more rapid evolution of the Internet architecture. More recently, it is being rolled out in data center networks as a means to provide bandwidth guarantees to cloud applications. Efficient utilization of the shared substrate network resources is dependent on effective techniques for virtual network embedding (VNE), which maps virtual networks on physical substrate network resources. A significant body of research focused over the years on devising efficient algorithms for the VNE problem, mostly assuming that the substrate network remains operational at all times. In practice, however, physical link and node failures commonly occur as part of everyday operations, propagating in virtualized environments to multiple hosted virtual networks. Back in 2010 we removed this assumption introducing and formulating the Survivable Virtual Network Embedding (SVNE) problem by incorporating single substrate link failures. Since then, a number of research proposals extended SVNE in various ways to handle substrate link as well as node failures. In general the goal of SVNE is to achieve reliable embedding of virtual networks, i.e., a mapping of virtual network requests onto substrate network resources capable to survive substrate resource failures. In this talk, I will discuss the key challenges in this area and present some of our recent contributions to the design of reliable virtual data centers and virtual transport networks.
