In 2013, computer scientist and electrical engineer Radia Perlman introduced TRILL (Transparent Interconnection of Lots of Links), aiming to improve network routing efficiency compared to the Spanning Tree Protocol. While TRILL allowed dynamic data routing and reduced congestion, it highlighted the inadequate network infrastructure, prompting costly upgrades by businesses. Despite initial controversy over operational costs, the resulting improvements in network resilience and efficiency led to wider acceptance of Perlman's innovation.
