Radia Perlman, often called the “Mother of the Internet”, revolutionized networking with her Spanning Tree Protocol (STP) and contributions to Open Shortest Path First (OSPF). Her innovations enabled loop-free redundancy in Ethernet networks and fast, scalable routing in modern infrastructure. Beyond STP and OSPF, Perlman has worked on network security, PKI, and TRILL, ensuring the internet remains resilient and efficient. As we celebrate International Women’s Day, recognizing pioneers like Perlman reminds us of the vital role of women in shaping technology.
