Reducing the Network Workload for Virtual Desktop Infrastructure

Over the past decade, cloud computing services become pervasive in the industrial field in order to enhance the efficiency and reduce the TCO (Total Cost of Ownership). Virtual desktop infrastructure (VDI) provides the computing environment to the client, where the host server delivers the video images encoded on the host server. The client decodes the video images and then displays them on the screen. However, this scheme causes the heavy traffic and increases an overhead on the host server due to the frequent memory access. In this paper, we propose a novel method for reducing the network traffic and decreasing an overhead on the host server through the cyclic redundancy check (CRC) comparison of each frame. Experimental result shows the feasibility of our proposal.
