This session demystifies the conceptual issues in moving data across multiple hops. We give an overview of, and contrast the functionality of these technologies, including an overview of link state routing (used in OSPF and IS-IS), spanning tree (used in bridging and switching), distance vector (used in RIP), and path vector (used in BGP).

About the Presenter
Radia Perlman is a Distinguished Engineer at Sun Microsystems. Some of her contributions to the industry include inventing the spanning tree algorithm used by bridges and switches, and many of the algorithms necessary to make link state routing (IS-IS and OSPF) scalable and robust. She is the author of Interconnections and coauthor of Network Security. She has taught graduate and undergraduate level courses at Harvard and MIT, and is currently an adjunct faculty member of the University of Washington. She has about 60 issued patents, a Ph.D. in computer science from MIT, and an honorary doctorate from KTH, the Royal Institute of Technology of Sweden.
