NDN-RTC is a videoconferencing library that employs Named Data Networking (NDN), a proposed future Internet architecture. It was designed to provide a platform for experimental research in low-latency, real-time multimedia communication over NDN. It aims to provide an end-user experience similar to Skype or Google Hangouts, while implementing a receiver-driven approach that takes advantage of NDN’s name-based forwarding, data signatures, caching, and request aggregation. As implemented, NDN-RTC employs widely used open source components, including the WebRTC library, VP9 codec, and OpenFEC for forward error correction. This paper presents the design, implementation in C++, and testing of NDN-RTC on the NDN testbed using a demonstration GUI conferencing application, ndncon, which provides HD videoconferencing over NDN to end-users.
