This Podcast and Video was originally posted on Silvano Gai’s blog here.

In this podcast, I interview Dinesh Dutt, a well known engineer and author, and ask him to explain the application of the Clos topology to data center networks, used in enterprises and clouds.

This first short video is an introduction to the topic.


The following podcast goes into more details about Clos networks and compares them with access-aggregation-core networks.


These two pictures, from Dinesh book, Cloud Native Data Center Networking may be helpful in following the discussion.
