Journal ArticleDOI
Network Function Virtualization: State-of-the-Art and Research Challenges
TL;DR: In this article, the authors survey the state-of-the-art in NFV and identify promising research directions in this area, and also overview key NFV projects, standardization efforts, early implementations, use cases, and commercial products.
Proceedings ArticleDOI
Design and evaluation of algorithms for mapping and scheduling of virtual network functions
TL;DR: This paper formulates the online virtual function mapping and scheduling problem and proposes a set of algorithms for solving it and proposes three greedy algorithms and a tabu search-based heuristic.
Proceedings Article
On the merits of SVC-based HTTP Adaptive Streaming
Jeroen Famaey,Steven Latre,Niels Bouten,Wim Van de Meerssche,Bart De Vleeschauwer,Werner Van Leekwijck,Filip De Turck +6 more
TL;DR: The performance of AVC- and SVC-based HAS is characterized in terms of perceived video quality, network load and client characteristics, with the goal of identifying advantages and disadvantages of both options.
Proceedings ArticleDOI
Dynamic resource management in SDN-based virtualized networks
TL;DR: This paper uses the SDN control plane to efficiently manage resources in virtualized networks by dynamically adjusting the virtual network (VN) to substrate network (SN) mappings based on network status, and extends an SDN controller to monitor the resource utilisation of VNs.
Journal ArticleDOI
In-network quality optimization for adaptive video streaming services
TL;DR: Several centralized and distributed algorithms and heuristics are proposed that allow nodes inside the network to steer the HAS client's quality selection process and are able to enforce management policies by limiting the set of available qualities for specific clients.
