In this 2009 portrait of Radia Perlman, she wears a blue linen top with silver filigree buttons and faces the camera with a friendly smile. Her graying brown hair is pulled back behind her ears and between her open hands she holds an open copy of her book "Interconnections: Bridges, Routers, Switches, and Internetworking Protocols"

Radia Perlman invented the algorithm for STP, putting basic traffic control into place for the internet. It provided automatic backup paths and disabled links not part of the tree, leaving a single, active path between any pair of network nodes.
Her more recent contributions include the invention of the TRILL protocol, which corrects some of the shortcomings of spanning trees and lets Ethernet make optimal use of bandwidth.
