Algorhyme – Dr. Radia Perlman

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.

The Spanning Tree Protocol was developed by Dr. Radia Perlman, who gave the idea in her poem “Algorhyme” which is based on “Trees” by Joyce Kilmer.
