TI  - Performance evaluation of WebRTC-based online consultation platform
AB  - Information technologies give patients the opportunity to communicate with medical professionals remotely.Telemedicine uses these technologies to provide advanced healthcare and medical services. We present a medical onlineconsultation application based on Web Real-Time Communications (WebRTC) technology enabling chat, audio, andvideo calls. Communication architecture and protocols of the application are explained in detail. Additionally, theuser interface of the application is shown via performed calls. The application is tested and evaluated on differentnetwork connections (3G, 4G, local, and DSL) and different browsers and mobile operating systems (Android, Chrome,Firefox, Internet Explorer, iOS, Opera, Safari). During calls, communication quality parameters such as round-triptime (RTT) and packet loss, obtained via the WebRTC application programming interface, are analyzed. 3G, 4G, andlocal connections show low packet losses (<1%). Packet losses are high (>1%) in Android, Chrome, iOS, Opera, andSafari for DSL connection, but RTT values are low (<100 ms) in all different conditions excluding iOS. In the presentedapplication, RTT and packet loss remain lower than 100 ms and 1%, respectively, in various scenarios, indicating goodcommunication quality. RTT and packet loss are related to total time and hang time parameters, which describe thenecessary time to establish and to end a call. It is shown that communication quality of the application can simply bemeasured by analyzing the total time parameter. This enables predictable information for communication quality forWebRTC-based applications without continuously monitoring RTT and packet loss for the first time.
