Abstract

This study proposes a conference bridge that cooperates with both the WebRTC layered simulcast and the Software Defined Networking architecture in order to improve WebRTC video streaming. The proposed bridge divides the functionality of a classic Selective Forwarding Unit into two parts. The selection of layers is performed by the SDN controller and the forwarding of layered video is still accomplished by the bridge. The bridge and the SDN controller exchange data on the state of the transmitted video stream and the state of the network. The proposed solution was implemented in the Jitsi Videobridge and tested in the GEANT testbed network. The results showed that our solution significantly reduces problems related to available throughput overshooting, which is typical for layered simulcast.

This work was supported by the Polish Ministry of Science and Higher Education with the subvention funds of the Faculty of Computer Science, Electronics and Telecommunications of AGH University.
