Efficient transmission of rendering-related data using the NIProxy

Despite the emergence of broadband Internet connections, client downstream bandwidth remains a scarce resource and should hence be managed judiciously. Based on this observation, we have previously introduced the NIProxy, a network intermediary supporting automatic client band-width management. However, the results presented in our previous work were generated using “artificial ” test appli-cations whose bandwidth management requirements could be satisfied using relatively straightforward strategies. In this paper, we evaluate the NIProxy’s suitableness to man-age client downstream bandwidth in a realistic, more com-plex networked application. The considered application supports real-time audiovisual user communication and in addition employs an advanced rendering scheme which imposes a number of specific requirements regarding the distribution of rendering-related data to clients. Through the presentation of representative experimental results, we demonstrate that the NIProxy is not only capable of ful-filling these requirements but also effectively improves the Quality of Experience (QoE) provided to users of the con-sidered application.
