Radia Joy Perlman

Radia Joy Perlman is a pioneering computer scientist, network engineer, and author renowned for her foundational contributions to network protocols and security. She is best known for inventing the Spanning Tree Protocol (STP), which revolutionized network bridging, and the TRILL protocol, which improves Ethernet efficiency. Her work spans network design, security algorithms, and self-organizing systems.

Perlman earned her Ph.D. in Computer Science from the Massachusetts Institute of Technology (MIT) in 1988. Her doctoral thesis on Byzantine-robust routing protocols laid the groundwork for resilient network design. She has taught courses at institutions including the University of Washington, Harvard University, MIT, and Texas A&M.

Her research focuses on network scalability, security, and self-organizing systems. Recent publications include the third edition of her seminal book on network security (2022) and the RFC 6325 specifying TRILL. Her work addresses challenges in distributed algorithms, link-state routing, and PKI trust models.

Perlman has received numerous accolades, including:

• National Inventors Hall of Fame (2016)
• Internet Hall of Fame (2014)
• SIGCOMM Award (2010)
• USENIX Lifetime Achievement Award (2006)
• ACM Fellow (2016)
• IEEE Fellow (2008)
