Looking for audiovisual resources on Clos topologies
Hi all, I recently read a APNIC blog post about LINE's network redesign [0] into a Clos topology. That lead to me RFC7938 [1] which has a fairly minimal explanation of the topology design itself. I was wondering if there are any NANOG or other *NOG talks explaining the Clos topology in a more audiovisual format. I figured I ask here before I go looking on a search engine. Thanks in advance.

From the APNIC blog:
"In the case of LINE's network, where all servers in the data centre are identified by eBGP, more than 10,000 ASNs are required." They've traded L2 VLAN complexity for L3 ASN complexity. What's the old saying in computer science? "All problems can be solved by adding a level of redirection"?

Apparently, "simplicity" is the new euphemism for "let's push all the surprising emergent effects of our design to someplace new..."

Thank you very much Hugo, I'll give these a look. -- Sadiq Saif https://sadiqsaif.com
