The First International Workshop on Security in NFV-SDN (SNS2016) in conjunction with the 2nd IEEE NFV-SDN conference, 7-9 November, Palo Alto, California, USA Workshop website: http://computing.derby.ac.uk/sns2016/
CALL FOR PAPERS Network Function Virtualization (NFV) and Software Defined Network (SDN) have changed the networking industry dramatically. NFV virtualizes network services by utilizing virtualization technologies to reduce the dependency on underlying hardware. NFV provides many benefits such as faster service enablement, ease of resource management and lower OPEX and CAPEX. SDN separates the control functions from the underlying physical network by decoupling the control and data planes. SDN provides many benefits such as reduced More >
Single Root I/O virtualization (SR-IOV) in networking is a very useful and strong feature for virtualized network deployements.
SRIOV is a specification that allows a PCI device, for example a NIC or a Graphic Card, to share access to its resources among various PCI hardware functions:
Physical Function (PF) (meaning the real physical device), from it a number of one or more Virtual Functions (VF) are generated.
Supposedly we have one NIC and we want to share its resources among various Virtual Machines, or in terms of NFV various VNFCs of a VNF.
We can split the PF into numerous VFs and distribute each one to a More >
In this post we will show how to configure a compute node in OpenStack to launch Docker containers. We assume that you already have a working OpenStack installation. The configuration we describe below worked for OpenStack Juno, while the controller and compute nodes were running Ubuntu 14.04 LTS.Install Docker and Docker driver for OpenStack on the compute node
Installing Docker in Ubuntu (Docker only works for 64 bit Ubuntu OS):sudo sh -c "curl https://get.docker.io/gpg | apt-key add -" sudo sh -c "echo deb http://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list" sudo apt-get update sudo apt-get install lxc-docker 1234 sudo sh -c "curl https://get.docker.io/gpg | apt-key More >
In the frame of the EU funded ICT T-NOVA Project, Medianetlab will host one of the project’s pilot sites. The project has presented an initial reference demonstrator architecture based on the integration of Openstack and Opendaylight constituting the Virtualised Infrastructure Manager for the Network Function VIrtualisation Infrastructure (NFVI. The first take on T-NOVA high-level architecture of the project is presented in the public deliverable D2.21.
Medianetlab provides lessons learned and guidelines used for the appropriate deployment from scratch of ODL, plus Openstack over Ubuntu using GRE networking. The setup and the details of the deployment setup and configurations used are More >

The NFV-focused T-NOVA EC/FP7 research project, led by MNL, released its second specification document, proposing an integrated top-down NFV system architecture for the provision of Virtual Network Functions as-a-Service. The T-NOVA architecture reuses ETSI NFV concepts for the lower architectural layers, while it introduces novel entities, including an NFV Marketplace with the aim of accelerating the market uptake of the VFNaaS business case. The defined architecture is reasonably complex and feasible to realise, being compatible with existing state-of-the-art IT and network infrastructures and will be fully implemented in the course of the project.
T-NOVA project released its first specification document, identifying use cases and requirements for an integrated Virtual Network Functions as-a-Service (VNFaaS) platform, such as the T-NOVA system. From a business point of view, the document proposes multiple value chain configurations, involving actors such as Infrastructure Providers, VNFaaS Service Providers and Function Developers. Elementary VNFaaS use cases cover all technical and commercial aspects and include: service composition, trading, provision, scaling, monitoring, billing and termination. High-level system requirements are derived from the list of use cases. Read the document here.
MNL, as T-NOVA coordinator, in liaison with projects NetIDE, UNIFY and SECURED co-organised a session on “Open platforms and SDN-NFV_a paradigm shift to boost innovative Internet services and applications” at Future Internet Assembly, Athens, March 2014. The session brought together industry experts for a discussion on how open platforms could pave the way toward an innovative way to build Internet applications and services leveraging on the emerging “softwarization” of networks and data-centers.
FP7 ICT T-NOVA was organised and hosted at NCSR Demokritos premises by MediaNet Lab. Project T-NOVA has officially started at 1/1/2014 and its duration is 3 years. The project is coordinated by NCSRD (Dr. A. Kourtis).
With the aim of promoting the NFV concept, T-NOVA introduces a novel enabling framework, allowing 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. Virtual network appliances (gateways, proxies, firewalls, transcoders, analyzers etc.) can be provided on-demand as-a-Service, eliminating the need to acquire, install and maintain specialized hardware at customers’ premises.

MNL presented a study on the effects of Video Transcoding Parameters on Event Detection for Surveillance Systems
Dr. Emmanouil Kafetzakis presented a full paper at IEEE International Symposium on Multimedia (ISM), held at Anaheim Marriott Hotel, California, U.S.A., 9-11 December 2013. The ISM conference is an international forum for researchers to exchange information regarding advances in the state of the art and practice of multimedia computing, as well as to identify the emerging research topics and define the future of multimedia computing. The paper, entitled “The Impact of Video Transcoding Parameters on Event Detection for Surveillance Systems”, explains the need for transcoding and studies different video quality metrics. Commonly used algorithms for motion and person detection are More >
