To satisfy the ever increasing demand for computational resources, high performance computing systems are becoming larger and larger. Unfortunately, the tools supporting system management tasks are only slowly adapting to the increase in components in computational clusters. Virtualization provides concepts which make system management tasks easier to implement by providing more flexibility for...

We introduce XMLVM, a Turing complete XML-based programming language based on a stack-based, virtual machine. We show how XMLVM can automatically be created from Java class-files and .NET’s Intermediate Language. While the programmer is never directly exposed to XMLVM, we provide tools based on XMLVM for tasks such as cross-language functional testing or code migration.

To resolve the challenges of forensic investigation in virtual networks, we present a new forensic framework called “Virtual Network Forensic Process”. Based on this framework we present the design, implementation and workflow of ForCon d a forensic controller to implement network investigation in OpenFlow controlled networks using Open vSwitch. Current trends bear out that virtualization techn...

Various numbering schemes are used to track different versions and revisions of files, software packages, and documents. One major challenge in this regard is the lack of an all-purpose, adaptive, comprehensive and efficient standard. To resolve the challenge, this article presents Quadruple Adaptive Version Numbering Scheme. In the proposed scheme, the version identifier consists of four integ...

In this paper, we examine migration techniques of mobile agents in Java. We identify the problems in Java technology, classify different migration styles and present possible solutions and related work. The proposed classification distinguishes between code migration, execution migration and data migration. The classification defines a partial order to compare different migration approaches. Fo...

Recently, multicore processor and virtualization become popular in research and application. And an even newer tendency is to deploy virtualization on multicore processor platform. This means on a physical server, several isolated and high performance virtual environments are provided, and concurrent program has a chance to run in a multicore virtualized environment. But most virtual processor ...

Virtual machine (VM) is an important mechanism to multiplex computer resource. The increasing popularity of Grid computing and Peer-to-Peer systems has renewed research interests in dynamic and adaptive virtual machines. Service migration is a vital technique to construct reconfigurable VMs. By incorporating mobile agent technology, VM systems can improve their resource utilization, load balanc...

Cloud Computing provides various services to the customer in a flexible and reliable manner. Virtual Machines (VM) are created from physical resources of data center for handling huge number requests as task. These tasks executed VM at which needs excess hosts satisfying request. The migration solves this problem by migrating one host another makes available any time. This process is carried ou...
