Tiff In Tech - In 1985, there was a massive problem threatening to break the entire internet. #tech #stem
In 1985, the internet faced a significant threat due to a flaw in early computer networks that caused broadcast storms, where messages would loop endlessly, potentially collapsing the entire network. Radia Perlman addressed this issue by developing the Spanning Tree Protocol over a single weekend. This algorithm automatically prevents network loops and remains a fundamental component in almost every network today. Beyond this, Perlman considers her most important work to be in making networks self-healing. She developed algorithms for network fault tolerance, allowing networks to automatically detect failures and reroute traffic in milliseconds without human intervention. Her contributions, particularly with the ISIS protocol, are crucial for maintaining the reliability of large networks.
