What it is
Perlman designed an algorithm that automatically computes a loop-free logical topology for Ethernet networks with redundant links, disabling the spare paths while keeping them ready as a fallback if others fail.
What it led to
- IEEE 802.1D standardisation (1990)
- Rapid Spanning Tree Protocol (RSTP, 2001)
- Multiple Spanning Tree Protocol (MSTP) and modern alternatives such as Shortest Path Bridging
