Optimizing WebRTC Video Conferencing Platform Assisted by SDN Approach

To support the best path among several paths, the network must choose the path with the best path to support Quality of Service (QoS), especially for real-time interactive video applications, such as distance learning and video conferencing. As long as the chosen routing protocol path is fixed by network topologies such as integrated services (ISs), which may not provide the highest possible performance. In addition, software-defined networking (SDN) intelligence with web-based real-time communications (WebRTC) can determine the most efficient data packet routing, which reduces latency and improves real-time communications. The main objective of this paper is to build and implement different contributions using SDN with WebRTC for real-time interactive video to determine the quality of service using Python language based on Oracle Virtual Box Manager. Thus, a new environment called WRTSDN is achieved using WebRTC with SDN technology to choose the network architecture to obtain the best path and wide area of the network. The WRTSDN protocol was implemented on 13 nodes of 11 switches and 2 hosts (sender and receiver). The results of the WRTSDN prototype implementation were shown using several metrics such as: network delay, network throughput, and message complexity. Also, this technique is novel using WebRTC with SND to obtain better paths with low latency, jitter, bandwidth, and delay. Moreover, this work faced many challenges by integrating WebRTC with SDN, applying metrics, analyzing the results.
