Abstract

Videoconferencing system is widely and successfully used on the Internet and standard/high definition videoconferencing is a new heated topic in research. However, researches in various videoconferencing systems (e.g. Access Grid, DVTS, VLC, and Ultra Grid) are faced with the problem of scalability. Bandwidth is the primary factor that limits the system capacity. In this paper, we propose a scalable and distributed standard definition videoconferencing system and design its architecture as well as forwarding model. We use several data stream transmitters to cooperatively forward video streams and design the system architecture, components' behaviors, and forwarding models on both control and data plane, with reasonable load allocation and balance. We also implement our idea based on DVTS as a multi-point standard-definition distributed DVTS Plus and test it on CERNET. Experiments on CERNET show that distributed DVTS Plus now supports higher system capacity, easier deployment and better scalability.
