Redar: A Remote Desktop Architecture for the Distributed Virtual Personal Computing

Some popular computing technologies, such as ubiquitous computing, grid computing and thin-client computing, bring people to a much more distributed and pervasive computing environment. Based on these innovative technologies, a distributed virtual personal computing (DVPC) paradigm is coming into being. One of the fundamental challenges in the DVPC design is the virtually integrated but physically distributed desktop system. We proposed Redar, a remote desktop architecture for the DVPC. Redar integrates various user interfaces from diverse service nodes into one virtual desktop, and present the virtual desktop to the ultra-thin user client. The user interfaces currently supported by Redar include the application GUIs as well as the mobile storage interfaces. The key components in Redar are the GUI merger, the virtual desktop manager, the ultra-thin-client and the transport protocols. We have implemented Redar in a DVPC prototype system. According to our evaluation, Redar shows perfect display latency, storage I/O, overhead, scalability and robustness
