Impact of Network Quality Deterioration on User’s Perceived Operability and Live-migration of Virtual Machines in Remote Desktop Environments

چکیده
The remote desktop environment (Virtual Desktop Infrastructure) is attracting interest as a way to strengthen security and support mobile access or telework. To realize the remote desktop environments, a remote desktop protocol is required to transfer information via a network about the user’s operations made on the keyboard and mouse on a terminal to the remote server. The growing popularity of remote desktop environments makes it important to determine the factors that govern the user’s perceived operability with a remote desktop protocol. It is also necessary important to find out the conditions for a wide-area live migration of virtual machines, to use resources efficiently in the remote desktop environments. This paper examines the impact of network quality deterioration (long network delay, high packet loss, small downlink bandwidth) on a user’s perceived operability in remote desktop environments, assuming RDP, PCoIP and ICA as remote desktop protocol. Next, this paper studies the impact of network quality on the performance of a live-migration of virtual machines in remote desktop environments.

Analytical evaluation of an innovative decision-making algorithm for VM live migration
In order to achieve the virtual machines live migration, the two "pre-copy" and "post-copy" strategies are presented. Each of these strategies, depending on the operating conditions of the machine, may perform better than the other. In this article, a new algorithm is presented that automatically decides how the virtual machine live migration takes place. In this approach, the virtual machine m...
متن کاملA Versioning Approach to VM Live Migration
In the context of virtual machines live migration, two strategies called “pre-copy” and “post-copy” have already been presented; but each of these strategies works well only in some circumstances. In this paper, we have a brief presentation of QAVNS and then introduce a new approach which is based on the concept of "informational object", assigning QAVNS-scheme-revision number, and observing th...
متن کاملA Near Optimal Approach in Choosing The Appropriate Physical Machines for Live Virtual Machines Migration in Cloud Computing
Migration of Virtual Machine (VM) is a critical challenge in cloud computing. The process to move VMs or applications from one Physical Machine (PM) to another is known as VM migration. In VM migration several issues should be considered. One of the major issues in VM migration problem is selecting an appropriate PM as a destination for a migrating VM. To face this issue, several approaches are...
متن کاملCyberLiveApp: A secure sharing and migration approach for live virtual desktop applications in a cloud environment
In recent years we have witnessed the rapid advent of cloud computing, in which the remote software is delivered as a service and accessed by users using a thin client over the Internet. In particular, the traditional desktop application can execute in the remote virtual machines without re-architecture providing a personal desktop experience to users through remote display technologies. Howeve...
متن کاملA version numbering scheme for informational objects used in VM live migration
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...
