RESTful HTTP WebRTC Testing OVERVIEW Web real-time communications (WebRTC) technology enables real-time communication via browsers. Service providers have deployed WebRTC and are doing trials with the technology to extend their IMS services such as voice over IP (VoIP), voice over LTE (VoLTE), video over LTE (ViLTE) and rich communication services (RCS) to Internet (web) users, hence enabling real-time communication between IMS and web users such as voice, video and chat. The interworking between IMS and web users is made possible by the WebRTC gateway, which translates signaling and transcodes...

RESTful HTTP WebRTC Testing RESTFUL HTTP WebRTC specifications do not define standard web signaling protocol, leaving web application architects and developers to decide. The signaling protocol is a requirement to transmit and exchange user device capabilities such as codec and ICE credentials from one endpoint to another in order to set up the endpoint for a communication session. Despite the flexibility and freedom provided to the application designers to choose the signaling protocol, having no standard signaling protocol introduces challenges in delivering interoperable WebRTC services. To...

RESTful HTTP WebRTC Testing 2) End-to-end IMS network testing with a mix of different types of endpoints, such as WebRTC, VoLTE and ViLTE endpoint. In this test configuration, httpFlex is used together with the volteFlex and hssFlex applications to test the IMS network; httpFlex emulates WebRTC endpoints, volteFlex emulates VoIP/VoLTE/ViLTE endpoints while hssFlex emulates PCRF. SUT = IMS RESTful HTTP EXFO WebRTC UE Diameter EXFO PCRF KEY USE CASES Simulates millions of WebRTC enpoints and other network devices for WebRTC gateway testing, thus enabling selection of the right gateway for WebRTC...
