Broadcasters are building studio architectures based on commercial off-the-shelf (COTS) IT hardware because of advantages such as cost reduction, ease management, and upgradation. Media function virtualization (MFV) leverages IP networking to transport media streams between virtual functions (VMFs), where they processed. service deployment in an MFV environment entails solving the VMF-FG schedu...

With the advent of World Wide Web, the life of every person has changed drastically. No one can imagine a computer without being connected to the Internet. This dependency is likely to grow in coming years with the adoption of technologies like virtualization and cloud computing. Cloud Computing and Virtualization is one of the foremost technology which has attracted many researchers recently, ...

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...

Survivability in networks has always been an important issue and lately becomes for network virtualization. Network virtualization provides to run multiple virtual networks on a shared physical network. Since a failure in the physical network can affect several virtual resources, therefore, the survivability has to be considered in the embedding of the virtual resources. In this paper, we prese...

Due to trends like Cloud Computing and Green IT, virtualization technologies are gaining increasing importance. They promise energy and cost savings by sharing physical resources, thus making resource usage more efficient. However, resource sharing and other factors have direct effects on system performance, which are not yet well-understood. Hence, performance prediction and performance manage...

As virtualization technology gains a stronger foothold in IT departments, many questions are being raised: " How will this technology affect my existing security posture? " ; " What new concerns need to be addressed to mitigate this risk? " and " What elements of risk does virtualization share with physical deployments? " As you would expect, there is no one size fits all solution to security, ...
