T-NOVA: A marketplace for virtualized network functions
TLDR
An integrated architecture is outlined, designed and developed within the context of the EU FP7 T-NOVA project, which allows network operators not only to deploy virtualized Network Functions (NFs) for their own needs, but also to offer them to their customers, as value-added services (Network Functions as-a-Service, NFaaS).
Enhancing VNF performance by exploiting SR-IOV and DPDK packet processing acceleration
TLDR
The results demonstrate that significantly higher packet throughput performance can be achieved when using SR-IOV and DPDK in unison in comparison to packet processing with the native Linux kernel network stack.
Survey of cross-layer proposals for video streaming over Mobile Ad hoc Networks (MANETs)
TLDR
A survey of 44 studied papers on cross-layer mechanisms in MANETs, comparing tools, parameters and metrics used for their evaluation and indicatively describes in more detail some of these proposals.
On the applications of efficient NFV management towards 5G networking
TLDR
The paper leverages the emerging paradigm of Network Function Virtualization (NFV) in an attempt to outline from the network management point of view the current trends on the road to 5G region and some key new concepts about network and small cell virtualization have been introduced.
T-NOVA: An Open-Source MANO Stack for NFV Infrastructures
TLDR
This paper presents a full software-based management and orchestration (MANO) stack which operates with OpenStack and OpenDaylight controllers and has the in-built functionality to automate the key phases of the NFV service lifecycle, namely resource discovery and matching, service mapping, service deployment, and monitoring.
Joint assessment of Network- and Perceived-QoS in video delivery networks
TLDR
This article presents a network-agnostic framework for the joint assessment of N- and P-QoS, with the aim of correlating these two parameters for a specific network and service configuration.
NFV applicability and use cases in satellite networks
TLDR
It is concluded that NFV adoption seems quite beneficial for the satcom sector in order to maintain its competitiveness, promote its inherent benefits and also to achieve the smooth integration of the satellite components and their indispensable satellite-specific capabilities into the future federated heterogeneous networks, within the 5G context.
Satellite-based sensor networks: M2M Sensor communications and connectivity analysis
TLDR
An efficient clustering methodology is proposed for the M2M sensor devices while the feasibility of the proposed system in terms of connectivity of the satellite gateways using high data rate terrestrial links operating at frequencies above 10 GHz, is investigated.
Quantifying TV white space capacity: quantifying tv white space capacity:
TLDR
This article presents a generic methodology for determining the actual capacity of white spaces using a geolocation-based approach, that is, dynamic assignment of radio resources to TVWS networks according to their geographical location.
An integrating framework for efficient NFV monitoring
TLDR
The challenges of proper NFV monitoring are discussed, focusing on the process of collecting NFV Infrastructure (NFVI) metrics and processing them at Virtualised Infrastructure Management (VIM) level, and an open-source integrating framework for efficientNFV monitoring is presented.
