Hello The draft SRv6-mobile-userplane seems to use the term "anchor" or "anchoring" quite a lot, but what exactly is meant is much unclear. It looks to me that the meaning changes during the progression of the text, or depends on the context. As it appears to be such key term of the draft I would recommend that you define it somewhere in this document.
In details: On page 7 you talk about "anchoring SID" and "next anchoring point". In the traditional mobility settings there is one anchoring point. So, I do not know what is "next anchoring point". Then on page 17 you mention "anchoring functionality". What is this functionality exactly? Has it something to do with mobility anchors as in "Distributed Mobility Anchoring" and/or "Proxy Mobile IPv6 extensions for Distributed Mobility Management" drafts that also talk about mobility anchors? Finally, the last sentence of the draft " It's notable that SRv6's network programming nature allows a flexible and dynamic anchor placement." Given all the options of the anchoring in this draft, I do not know that this means? Flexible mobility anchor placement? Next anchor placement? Anchoring SID placement maybe? What do you mean by saying "All control-plane protocols are expected to leverage these function type-codes to signal each function" ? Does it mean that all control planes need to be implemented to use these function types? Or carry them or what exactly? Best regards Hannu
