Dr. Radia Perlman
Dr. Perlman is a Distinguished Engineer at Sun Microsystems. She is known for her contributions to bridging (spanning tree algorithm) and routing (link state distribution) as well as security (sabotage-proof networks).
She is the author of the textbook Interconnections: Bridges and Routers, and co-author of Network Security: Private Communication in a Public World, two of the top 10 Networking reference books, according to Network Magazine.
Dr. Perlman is one of the networking industry's 25 most influential people, according to Data Communications Magazine. She has about 50 issued patents in the fields of routing and security. She has a PhD in computer science, degrees in mathematics from MIT, and an honorary doctorate from the Royal Institute of Technology in Sweden.
Radia Perlman's work has had a profound impact on the field of networking. She was recently featured in the 25th anniversary edition of Data Communications magazine as one of the 25 people whose work has most influenced the industry. She is the creator of the spanning tree algorithm upon which bridges (switches) are based, and the algorithms that allow robust and efficient link state routing, upon which all modern link state routing protocols (such as IS-IS, OSPF, and PNNI) are based. Radia designed IS-IS, Simple Multicast, and sabotage-proof routing. She is also co-author of Network Security: Private Communication in a Public World. Both of her books were listed in the top 10 most useful networking reference books in the March, 1988 issue of Network Magazine. She is currently a Distinguished Engineer at Sun Microsystems, Inc. She holds about 50 patents and a Ph.D. from M.I.T.
