Hi Darren,

It's always good to hear from you. Even when we disagree, the conversation is always civil and thought provoking.

I am glad to hear that you are open to arguments suggesting that your analysis might be incorrect. So, I accept your challenge to produce a document that describes the advantages of SRm6 over SRv6, as well as the differences between SRm6 and SRv6. Expect some operational hoarse-sense as well as some architectural deep-diving.

While the document will include words on scale and performance, running code will provide the most reliable evidence.

                                                                                                         Happy holidays,
                                                                                                               Ron

Subject: SRm6: Motivation?

Hi Ron, to follow up on what was said at the mic.

The current community analysis, comparing existing solutions (SRv6 and SR-MPLS for IPv6) with SRm6, had the following result:
- a lot of differences (Architecture, Dataplane, Controlplane) and hence engineering cost
- scale, performance and complexity drawbacks
- no genuine advantage

Hence, the very first thing you need to do is to clearly compare your solution with respect to SRv6 and SR-MPLS and demonstrate why the above analysis is incorrect.

Only with such a logical analysis, will the community be able to judge whether this proposal should be pursued within SPRING.

Thanks
   Darren
