Radia Joy Perlman came up with a brilliant solution in just a few days to make computer networks both larger and more reliable.

She created #STP, which allows networks to have backup paths for safety, but turns off any extra paths that could cause a loop. This leaves just one clear, active path for data to travel between any two points on the network.

Perlman even wrote a short #poem, called "Algorhyme," to explain how STP works: 🤩

I think that I shall never see
A graph more lovely than a tree.

A tree whose crucial property
Is loop-free connectivity.

A tree which must be sure to span
So packets can reach every LAN.

First the root must be selected.
By ID it is elected.

Least cost paths from root are traced.
In the tree these paths are placed.

A mesh is made by folks like me
Then bridges find a spanning tree.

From @joannechocolat

Radia Joy Perlman (born 1951) is an American computer programmer, network engineer, & major figure in assembling the networks and technology to enable what we now know as the Internet.

Personal note:

First of all, I love her name! "Radiating (happy, bright) Joy" - and all the photos of her I have seen seem to bear that out! 😊

Her best-known contribution is the Spanning Tree Protocol (#STP), which transformed Ethernet from a technology limited to a few hundred nodes confined w/i a single building into a technology that can create large networks with hundreds of thousands of computers, & made fundamental contributions to internet routing, making it more resilient, scalable & easy to manage. The protocols she designed in the 80s remain widely deployed today.

At the time, if a network had extra connections (called redundant links), it could create a "loop." A loop would cause data to circle around forever, flooding the network and causing it to fail.
