  • FastDesk: A remote Desktop Virtualization system for multi-tenant
    Future Generation Computer Systems, 2017
    Co-Authors: Tao Song, Jiewei Wu, Ruhui Ma, Alei Liang, Tao Gu, Jiajun Wang, Zhengwei Qi
    Abstract:

    Classical remote Desktop systems are considered for a single host, thus hindering their applicability on Virtualization environment. Remote Desktop Virtualization is rising in the recent years as a new advanced extension to Virtualization technology. However, existing remote Desktop Virtualization solutions introduce weak performance in relation to response time, video quality, and cost saving. This paper proposes a novel remote Desktop Virtualization system for multi-tenant, namely FastDesk, which is based on a server-push mode streaming mechanism and a heuristic virtual Desktop placement algorithm. Through extensive experiments, the results show that FastDesk outperforms other popular platforms in terms of bandwidth with less than 2 Mbps and 94% video quality. Meanwhile, it creates the minimal resource wastage compared with other virtual machine placement algorithms. Furthermore, the proposed FastDesk achieves low CPU utilization, low bandwidth and good scalability. At last, to widen its applicability, FastDesk has been implemented on VirtualBox for running 3D programs.

  • sridesk a streaming based remote interactivity architecture for Desktop Virtualization system
    International Symposium on Computers and Communications, 2013
    Co-Authors: Jiajun Wang, Haibing Guan
    Abstract:

    In recent years, Desktop Virtualization trends to be a new extension of Virtualization framework. The existing Desktop Virtualization systems suffer performance degradation in terms of response time and video quality. However, previous remote access approaches are designed for standalone architectures and require semantic information which is not transparent to OS. So they are not feasible in Desktop Virtualization systems. In this paper, we propose SRIDesk, a Streaming based Remote Interactivity architecture for Desktop Virtualization system. SRIDesk resides in the host through intercepting virtual display device, which is transparent to guest OS and its applications. SRIDesk integrates server-push streaming mechanism with H.264 encoder into Virtualization system, which provides high quality display with low bandwidth consumption and low latency of interaction. We have implemented the SRIDesk prototype in a KVM system. Experimental results show that SRIDesk has low CPU-load, low bandwidth and good scalability. We compared SRIDesk with other popular platforms, including X, VNC, RDP and THiNC. SRIDesk outperformed other systems in bandwidth with no more than 2Mbps and 94% video quality. SRIDesk also achieved lowest latency in WAN environment among all systems.

  • vmobidesk Desktop Virtualization for mobile operating systems
    IEEE Access, 2020
    Co-Authors: Peiyu Liu, Wenzhi Chen, Kai Hwang
    Abstract:

    Smart mobile devices have significantly increased the popularity of Bring-Your-Own-Device (BYOD) at work, as they benefit people’s daily lives. However, BYOD comes with several challenging issues such as limited hardware capacity, frequent upgrades of applications, and security and privacy concerns. Virtual Mobile Infrastructure (VMI), a general framework that provides more reliable and secure solution for BYOD, has therefore been proposed. The key of VMI is to host a mobile Operating System (OS) on a remote cloud data center, and run mobile applications on it. However, VMI faces performance challenge as it needs to display the entire virtualized Desktop on a mobile device while the real content of the Desktop is on a remote server. To address the performance challenge, we design and implement a VMI named vMobiDesk on top of Android with optimized network transfer mechanisms and display Virtualization. In particular, vMobiDesk focuses on virtualizing the display of Android Desktops, redirecting users’ input events, providing audio support and remote camera. The experimental results show that vMobiDesk has low Virtualization overhead, as well as enables mobile users to obtain good experiences with BYOD applications.

  • vmobidesk Desktop Virtualization for mobile operating system
    High Performance Computing and Communications, 2016
    Co-Authors: Pengfei Jiang, Zonghui Wang, Wenzhi Chen
    Abstract:

    With the rapid adoption of smartphones and tablets, virtual Desktop infrastructure (VDI) for mobile devices emerges as one of the key concept in mobile cloud computing (MCC). However, existing VDI products are originally designed for personal computer operating systems (e.g. Windows, Mac OS, Ubuntu, etc.). The user experience is greatly degraded while viewing and operating a PC Desktop from a smartphone or a tablet. In this paper, we propose techniques to virtualize the Desktop of mobile operating systems (e.g. Android, iOS, Winphone, etc.) for mobile users and we have implemented a prototype system on Android which is one of the most popular mobile operating systems. The experimental results show that our system enables mobile users to achieve almost the same experience as in the local while viewing and operating the remote mobile Desktops.

  • DMS - An original-stream based solution for smoothly replaying high-definition videos in Desktop Virtualization systems
    Journal of Visual Languages & Computing, 2014
    Co-Authors: Kui Su, Zonghui Wang, Xuequan Lu, Wenzhi Chen
    Abstract:

    Existing Desktop Virtualization systems suffer from a very limited performance in replaying high-definition videos remotely: intolerable CPU and bandwidth consumption, high response delay and poor video quality. In this paper, we propose an original-stream based solution to provide good user experience for replaying high-definition videos in Desktop Virtualization systems without any modification on applications and support most of prevalent high-definition video formats. In our solution, server's video content is not decoded on server but intercepted and delivered to client in its originally encoded state, so that the video content can be easily stored and transported in computer systems with high quality and low bandwidth. The encoded video content is intercepted in server's display driver, which enables HDR to work seamlessly with existing applications. The extremely CPU-intensive video decoding tasks are executed on client by using GPU-accelerated video decoding technology so that CPU can concentrate on other tasks. The experimental results validate our method and show that this proposed approach measurably outperforms state-of-the-art solutions.
