![]() ![]() She is most famous for her invention of the Spanning Tree Protocol (STP), which is fundamental to the operation of network bridges, while working for Digital Equipment Corporation. Her doctoral thesis at MIT addressed the issue of routing in the presence of malicious network failures. ![]() Perlman obtained a Bachelor's, Master's in Mathematics, and a Ph.D. Radia has been described as a pioneer of teaching young children computer programming. During research performed in 1974–6, young children-the youngest aged 3½ years, programmed a LOGO educational robot called a Turtle. Working under the supervision of Seymour Papert, she developed a child-friendly version of the educational robotics language LOGO, called TORTIS ("Toddler's Own Recursive Turtle Interpreter System"). Perlman has however criticised changes which were made in the course of the standardisation of the protocol.As an undergraduate at MIT she undertook a UROP (Undergraduate Research Opportunity), in lieu of course units, within the LOGO Lab at the (then) MIT Artificial Intelligence Laboratory. Perlman said that the benefits of the protocol amount to the fact that "you don't have to worry about topology" when changing the way a LAN is interconnected. Despite Perlman's concerns that it took the spanning tree protocol about a minute to react when changes in the network topology occurred, during which time a loop could bring down the network, it was standardised as 802.1d by the Institute of Electrical and Electronics Engineers (IEEE). Each bridge then mapped the network and determined the shortest path to the root bridge, deactivating other redundant paths. The algorithm implemented on all bridges in the network allowed the bridges to designate one root bridge in the network. Perlman utilised the fact that bridges had unique 48 bit MAC addresses, and devised a network protocol so that bridges within the LAN communicated with one another. Therefore loops could cause Ethernet frames to fail to reach their destination, thus flooding the network. Redundant paths in the network meant that a bridge could forward a frame in multiple directions. Building and expanding bridged networks was difficult because loops, where more than one path leads to the same destination, could result in the collapse of the network. It was required that the protocol should use a constant amount of memory when implemented on the network devices, regardless of how large the network was. While working as a consulting engineer at Digital Equipment Corporation (DEC) in 1984 she was tasked with developing a straightforward protocol which enabled network bridges to locate loops in a local area network (LAN). Perlman invented the spanning tree algorithm and the Spanning Tree Protocol (STP). So, how much is Radia Perlman worth at the age of 71 years old?
