Hello Everyone,

Today, I’d like to share with you some thoughts on a complex topic : The evolution of computer networks and what drives this evolution.

How did we transition from the traditional 3-tier architecture of our data centers (access, aggregation, core) to the Clos architecture (Leaf-Spine “Clos” architecture) we know so well today?

Some might say it’s simply a technical evolution driven by protocol limitations and/or cost considerations.
