Juniper recently posted some new videos on their YouTube channel covering Segment Routing. These videos feature my former colleague Ron Bonica as he provides a basic overview of Segment Routing (SR) including key concepts such as paths and segments before diving into how SR simplifies traffic engineering.
I definitely recommend checking these out for anyone interested in learning more about this emerging technology that is generating a lot of interest amongst the the Service Provider community.
