In recent decades, mixed-criticality systems have been widely adopted to reduce the complexity and development times of real-time critical applications. these systems, applications run on a separation kernel hypervisor, software element that controls execution different operating providing virtualized environment ensuring necessary spatial temporal isolation. The guest code can unmodified unawa...

In monolithic operating systems, the kernel is the piece of code that executes with the highest privileges and has control over all the software running on a host. A successful attack against an operating system’s kernel means a total and complete compromise of the running system. These attacks usually end with the installation of a rootkit, a stealthy piece of software running with kernel priv...

This paper reports on the state of the art of virtualization technology for both general purpose domains as well as real-time domains. There exits no entirely instantaneous data transmission/transfer. There always exist a delay while transmitting data, either in the processing or in the medium itself. However most systems are designed to function appropriately with a delay tolerance. This delay...

Virtualization is a fundamental part of cloud computing, especially in delivering Infrastructure as a Service (IaaS). Exploring different techniques and architectures of the virtualization helps us understand the basic knowledge of virtualization and the server consolidation in the cloud with x86 architecture. This paper describes virtualization technologies, architectures and optimizations reg...

A tape library is seldom considered as a viable place for constructing a file system for a sequential write/read device. Storage virtualization technology has become a buzzword in technology circles lately, in this paper we propose a tape library file system, called TLFS. The purpose of TLFS is to maintain a consistent view of mass storage so that the user can effectively manage it. Like disk f...

Cloud computing is one of the today’s largest hearing fields and exciting technologies, because it is flexible and scalable, also it reduces the cost and complexity of applications. The core technology that adds to the features of cloud computing is virtualization. Virtualization is a component of cloud computing. On the basis of virtualization cloud computing allows easy deployment of workload...

Virtualization is a technique used to model and simulate the cyber domain, as well as train and educate. Different types of virtualization techniques exist that each support a unique set of benefits and requirements. This research proposes a novel design that incorporates host and network virtualization concepts for a cyber warfare training platform. At the host level, hybrid virtualization com...

We propose a next generation Internet architecture that will allow natural sharing of resources among multiple organizations by dynamically reconfiguring and creating a virtual network for a particular application. Our architecture called "Internet 3.0" consists of a 3-tier object model. The bottom tier consists of a high-speed network infrastructure owned by multiple ISPs. The second tier cons...

The impact of Information and Communication Technologies on business models is posing new challenges. It has given birth to a new set of data and related applications. Changing business needs and the explosion of digital data have also created huge demand for massive and efficient storage. Increasing costs for electronic data storage and limited funds made people to think about cloud storage. S...
