“I think that I shall never see
A graph more lovely than a tree.”
Apparently adding a new switch to my home network has convinced my #Ubiquiti system that I need to explicitly pay attention to #SpanningTree Protocol. And so Radia Perlman's #Algorhyme (and protocol) comes to mind.
#Algorhyme
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 that 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.
