Hi Fan, Thanks for your prompt reply. I agree with your direction to redefine the target of this mechanism. In my view your draft was “inspired by DetNet” and intends to improve the functionality of SR. That is absolutely fine. :--))
Please, make it clear in the draft as well, that would avoid any misinterpretations. Thanks & Cheers Bala’zs From: Yangfan (IP Standard) <[email protected]> Sent: Monday, July 26, 2021 11:09 PM To: Balázs Varga A <[email protected]>; [email protected] Cc: spring <[email protected]>; [email protected] Subject: 答复: IETF-111 SPRING presentation on sr-redundancy-protection Hi Balazs, Thank you for your comments. As what Gyan mentioned during the presentation, this draft redefines redundancy protection as a general protection mechanism designed for SR network. Firstly, it is a general mechanism can be used in many uses cases, not only DetNet use case. Secondly, it applies to SR network, not a general IP or MPLS data plane solution which Detnet requires. Since the scope is changed, I don’t think redundancy protection is necessary to follow DetNet architecture. If redundancy protection is not a DetNet mechanism, I don’t think it should cover both P2P and P2MP services. We are happy to address the comments that relates to redundancy protection in next revision. Thanks.

This draft only p2p, so many DetNet use cases cannot be supported 3, Slide-9: there were many DetNet related comments on the list. Only some were addressed in the latest version of the draft. Thanks & Cheers Bala’zs
