About

Henning Schulzrinne is a pioneering computer scientist whose research has fundamentally shaped the architecture of modern Internet communications. His key contributions span Internet telephony, multimedia protocols, and next-generation networking. Schulzrinne is best known as the principal author of the Session Initiation Protocol (SIP), the foundational standard for Voice over IP (VoIP) and real-time multimedia sessions. This protocol, now ubiquitous in systems from Skype to enterprise telephony, has garnered tens of thousands of citations and transformed global telecommunications. He also co-developed the Real-Time Transport Protocol (RTP) and the Real-Time Streaming Protocol (RTSP), which are critical for streaming audio and video over the Internet. His work on "Thought communication and control" (2004, 66 citations) explored novel neural interfaces, while his recent "Computing Research Challenges in Next Generation Wireless Networking" (2021, 9 citations) addresses 5G and beyond. A Fellow of the IEEE and ACM, Schulzrinne has received numerous awards, including the IEEE Internet Award and the ACM SIGCOMM Award, cementing his legacy as a foundational architect of the Internet's communication infrastructure.
