I recently read a very interesting post on LinkedIn in which Urs Hölzle, one of the original Google network engineers, celebrated twenty years of Google network innovation. He provided links to the recent paper from Google describing how Google developed its datacentre network and how it has evolved since then. The paper describes how Google applied the Clos network topology in its datacentres and the early implementations of software-defined-networking that controlled data flows across the network.
One point that was really interesting, which came up in the comments to the article, is that Google implemented the original network routing code in Python.
Mr. Hölzle also linked to an independant research report that came out at the time. It provided the initial view of what Google was developing and is interesting to read almost 20 years after it was written.
Hello Brian, this comment is not about SDN but I have provided a demonstration that is plug and play of the FRR routing open source configured to run OSPF. It launches some 60 containers in a spider-like network inside a cloonix which is inside a podman container. Just download the podman from the http://clownix.net web site, run the podman with the command line provided in the web site and run the demo.

Go to “Test the spider web frr demo from within a podman”
And follow the instructions.
And thank you Brian for your network simulation website, you provide very valuable information about virtual networks!
