Mark Handley is a British computer scientist known for his pioneering contributions to the core technologies underpinning the modern Internet, including protocols for real-time multimedia communication, congestion control, and multipath networking. He is Professor of Networked Systems in the Department of Computer Science at University College London (UCL), a Fellow of the Royal Society, and has authored or co-authored numerous Internet standards that have enabled scalable audio and video traffic over the Internet. [1] [2] Handley's research has focused on network architecture, traffic control, routing, resource sharing, resilience, and security in large-scale systems. His early work included principal contributions to the Session Initiation Protocol (SIP), which became the key signaling protocol for Internet telephony, as well as Session Description Protocol (SDP), Protocol Independent Multicast - Sparse Mode (PIM-SM), TCP-Friendly Rate Control (TFRC), and Datagram Congestion Control Protocol (DCCP). He originated key concepts in Multipath TCP and founded the XORP open-source routing software project. More recently, he has advanced high-performance datacenter networks for AI workloads, including NDP and EQDS protocols, with elements of his work influencing standards in the Ultra Ethernet Consortium. [2] Since 2003, Handley has led research at UCL's Networks Research Group, following earlier positions at the International Computer Science Institute in Berkeley, where he co-founded the AT&T Center for Internet Research. He has served on the Internet Architecture Board and various IETF directorates, shaping long-term Internet development. In October 2024, he joined OpenAI to focus on networks for very large-scale AI clusters while maintaining a part-time affiliation with UCL. His contributions have been recognized with awards including the IEEE Internet Award (2012), the ACM SIGCOMM Award (2019), and election as a Fellow of the Royal Society (2019). [2] [1]
