Abstract:
Virtual Networks (VNs) have attracted considerable attention in the last years since they offer a flexible and economic approach to deploy customer suited networks and run their applications. Such applications have different requirements, such as topology, security, resilience, and thus pose different challenges to the network embedding problem. In the last three decades of research in distributed systems, one core aspect discussed is the one of synchrony, since it impacts directly the complexity and functionality of fault-tolerant algorithms. In this paper, we argue that VNs and a suitable VN embedding process offer both abstractions and techniques to discuss and address the support of applications with hybrid synchrony demands, thus contributing in core aspects of reliable distributed systems. This work introduces the general idea of Hybrid Synchrony Virtual Networks (HSVNs) and presents a mathematical model that formalises the embedding of HSVNs into a physical network. Our results show that the model proposed is able to, correctly and efficiently, allocate resources on the SN, in an optimal manner.
