ABSTRACT:
Thin-client computing offers a solution to the increasingly unmanageable costs of today's IT infrastructure. Thin-client computing moves user data and application management from the desktop to centralized servers in professional-managed data centres. Application service providers (ASPs) are using thin-client computing to enable desktop machines, web browsing terminals, and other low-cost embedded devices to function as simple user interface devices for accessing computational services over the Internet. ASPs have the potential to deliver easier-to-maintain computational services with reduced total cost of ownership.
A key enabling technology in thin-client computing is the remote display protocol. The protocol allows graphical displays to be served across a network to a client device, while applications and even window systems are executed on the server. Using such a protocol, the client transmits user input to the server, and the server returns screen updates to the client.
To assess the viability of the thin-client computing model, we are conducting a series of detailed experiments to quantify the performance of thin-client platforms for various application workloads. We focus on the network performance of remote display technologies. Our experiments include measurements of popular thin-client platforms such as AT&T VNC, Citrix Metaframe, Microsoft Terminal Services , Sun Ray, and Tarantella.
