Impact of Network Quality Deterioration on User's Perceived Operability in Remote Desktop Environments

Abstract

The remote desktop environment 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 users' 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 on a user's perceived operability in remote desktop environments, assuming RDP and PCoIP as a remote desktop protocol. Next, this paper studies the impact of network quality on the performance of a live-migration of virtual machines in virtual remote desktop environments.
