Hello Stefano I've seen Clarence presentation about Segment Routing at MWC in Paris. I like the concept of using IGP for signalling and to simply use existing tools like remote LFA for traffic protection. Traffic Engineering looks simple as well. My initial concern was around large label stack especially in cases where there is significant amount of Traffic Engineering going on. Clarence pointed out that this can be resolved with loose hops using just two labels in majority of the cases. I was also chatting to Stewart Bryant and he suggested compressing the label stack I belive you touched on that on page 6 in the ECMP context. I was wondering if this could be extended for strict and loose path signalled with single label only, so that we have the same label stack as in LDP/RSVP based solution. This probably would require additional signalling. IPv6 variant is looking interesting as well. I'm hoping that more details will appear in the draft shortly and we will have more discussion on the mailing list. In Section 2.2 comparative study has been mentioned could your share more details ? Also are there any plans to discuss segment routing in Berlin ? Thanks Patryk Konczyk
