NDN-RTC: Real-Time Videoconferencing over Named Data Networking

NDN-RTC is a real-time videoconferencing library that employs Named Data Networking (NDN), a proposed future Internet architecture. It was designed to provide an enduser experience similar to Skype or Google Hangouts, while taking advantage of the NDN architecture’s name-based forwarding, data signatures, caching, and request aggregation. It demonstrates low-latency HD video communication over NDN, without direct producer-consumer coordination, which enables scaling to many consumers through the capacity of the network rather than the capacity of the producer. Internally, 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.
