Abstract | A Massive Open Online Course (MOOC) requires a large, distributed conferencing system to allow synchronous e-learning that can improve the student learning experience. Using the currently available form of distributed conferencing, known as H.323, cascaded conferencing is less scalable, difficult to configure, inflexible and not robust. We have designed a Dynamic Cascaded Conferencing (DCC) method to address these issues. In DCC, a manager is chosen via a Highly Available load balancer to keep the conference together and provide easy configuration. We formulated an algorithm that calculates the optimum distribution path of audio and video based on network conditions and the capacity of each conference. The resulting path is a tree that can have many branches. Publish-subscribe messaging is used to synchronize data between conference servers, since it requires minimal resources. Also, we have determined the amount and type of resources that each conference server should reserve to allow server-to-server audio-video distribution and data synchronization. Our measurements and predictive model show that DCC is linearly scalable, and qualitative analysis reveals that DCC offers characteristics that are suited to distributed conferencing on a large scale |
