![]() ![]() This leaves a single, active path between any pair of network nodes. This setup provides automatic backup paths if an active link fails, and disables the links that are not part of the tree. She very quickly produced a solution that did exactly what the team wanted it to the Spanning Tree Protocol (STP), allows a network to deliver data reliably by making it possible to design the network with redundant links. Digital had been trying to get computers to share information in a reliable manner and asked for her help. Digital offered her a job she joined the firm in 1980. while making a presentation on network routing. While working for BBN, Perlman made an impression on a manager for Digital Equipment Corp. From there she accepted a position with Bolt, Berenek, Newman (BBN), a government contractor that developed software for network equipment. She attended the Massachusetts Institute of Technology, graduating with a SB degree in 1973 and an SM in 1976, both in mathematics. Her invention of the algorithm behind the Spanning Tree Protocol solved a challenging information routing problem and earned her the moniker “ Mother of the Internet.”īorn in 1952 in Portsmouth, Va., Perlman spent much of her childhood in New Jersey. Engineer and mathematician Radia Perlman was one of very few women involved in process at that time. Celebrating Garey High School InvenTeam's Patent Award!ĭuring the 1970s scientists and programmers were working hard on assembling the networks and technology to enable what we now know as the Internet. ![]()
