Home environments have a great potential of resource sharing and energy saving. More and more home computers are running on an always-on basis (e.g. media-centers or file-sharing clients). Such home environments have not been sufficiently analyzed regarding their energy-efficient operation, yet. This paper discusses network virtualization methods that are needed in future home environments to e...

Network Function Virtualization (NFV) takes advantage of hardware virtualization to undertake software processing for various functions, and complements the drawbacks of traditional network technology. To speed up NFV related research, we need a user friendly and easy to use research tool, which could support data center simulation, scheduling algorithms implementation and extension, and provid...

Virtualization services permit I/O subsystems and peripheral devices to be virtualized by placing select functionality on specialized cores and/or on cores situated ‘closer’ to devices. The approach is used to implement self-virtualized I/O (SVIO), which off-loads certain virtualization functionality onto the cores available on the I/O device, accelerating I/O functions, efficiently using key p...

Network virtualization is one of the topics that recently have been receiving attention in the research community. It is becoming evidently clear that network virtualization will be a major player in the shaping of the Future Internet. Many research projects around the world are studying different aspects of network virtualization: some are focusing on resource virtualization like Node, Server ...

Recent developments in networking hardware and software-defined networking have enabled full distribution of network control to reduce control latency and increase reliability. However, both, hardware and software of current white-box networking hardware are highly heterogeneous, which limits the deployment and operation of switch-local control applications. Furthermore, switch-local control ra...

Value-added services (e.g., overlaid video advertisements) have become an integral part of today’s Content Delivery Networks (CDNs). To offer cost-efficient, scalable and more agile provisioning of new value-added services in CDNs, Network Functions Virtualization (NFV) paradigm may be leveraged to allow implementation of fine-grained services as a chain of Virtual Network Functions (VNFs) to b...

The satellite industry is clearly committed to revisit and revamp the role of satellite communications within the 5G ecosystem. Central technologies being adopted in 5G networks such as Software Defined Networking (SDN) and Network Function Virtualization (NFV) are also anticipated to become key technological enablers for improved and more flexible hybridization of both satellite and terrestria...

Software Defined Networks (SDNs) have been recognized as the next-generation networking paradigm that decouples the network control plane from the data forwarding plane. A logically centralized controller is responsible for all the control decisions and communication among the forwarding switches. However, current traffic engineering techniques and state-of-the-art routing algorithms do not eff...
