The right tool for the job: Choosing where to use RSVP-TE or SR.

I noted that at NANOG64 this week in San Francisco, there are talks (both from Juniper) about both SPRING/Segment Routing and RSVP-TE. These are both protocols/technology approaches (since one can’t really call SR a protocol) that I’ve been involved in the evolution of over the last few years. A question that I’ve been asked more times than I’d like is why we chose to look at a new approach (SR) rather than go with a technology that exists RSVP-TE.

RFC5218, RSVP-TE and Segment Routing.

After my presentation at UKNOF on SR, Mark Townsley asked me whether I'd be interested in presenting to his class at the Ecole Polytechnique in Paris, around the thinking (from an ops perspective) of delivering the 5218 concept of "net positive value" through the SR technology, and how the existing protocols that are available might measure up against the criteria that 5218 gives us to consider. We managed to co-ordinate logistics, and I presented to INF566 on Wednesday afternoon, which was a really cool experience. It's always nice to see how networking is taught, and hear from students in such a high-ranking uni. I've included the slides below for posterity - Mark filmed the presentation, so perhaps there'll be video at some point in the future!

I recently gave a talk at UKNOF relating to Segment Routing/SPRING and the operational challenges that we are trying to resolve through it. You can see it on YouTube below - or the slides are on this site - SPRING Forward(ing) - UKNOF27
