[Teas] Some comments on draft-ali-teas-spring-ns-building-blocks

["Dongjie (Jimmy)" <[e-mail]>]

Hi authors,

Thanks for the presentation in the TEAS session in last week. Here are some comments on this draft:


1.      As discussed on the TEAS meeting, the terminologies in several drafts related to network slicing realization will be aligned, thus it is suggested the terminology in this document also aligns with the "new term" to be proposed.


2.      As this document lists the SR technologies which can be used for network slice realization in SR networks, the suggestion is it should also describe and reference draft-ietf-spring-resource-aware-segments and draft-ietf-spring-sr-for-enhanced-vpn which specifies the extensions to SR segments and the mechanisms to provide SR based VTNs.



3.      Section 8 of this document describes the "stateless network slice ID" concept and the mechanisms with different data planes. The general mechanism of introducing dedicated VTN identifier in data packet for per-VTN packet processing was described in draft-dong-teas-enhanced-vpn-vtn-scalability, thus there is some overlap in this part which needs to be solved in future versions.


Best regards,
Jie
