New infrastructure deployments is not "packet routing" and QoS is usually as strongly tied to policy as BGP is.
If you have an example of QoS relying on ML, I would be interested in reading more.
Who is using deep learning for packet routing and QoS decisions?
No one I know of, from the last time I did check on this topic. However, it seems possible to plug ML on top of something like OpenFlow. PM me if interested to look this up further.
Thanks. I was mostly interesting in seeing a source for maaku's statement of "Now ask yourself how decisions are made regarding new infrastructure deployments", as it seemed pretty condescending to me.
