[spring] [IPv6] WG Adoption call for Segment Routing Header encapsulation for Alternate Marking Method

2023-02-10 Thread Riccardo Sisto
Hi Joel, I was informed by Giuseppe Fioccola and Mauro Cociglio about the adoption call for the draft at: https://datatracker.ietf.org/doc/draft-fz-spring-srv6-alt-mark As the Alternate Marking Method is already used successfully as a passive measurement method with several protocols, I think

IMO,the method in this draft clearly defines the AM effective scope by data plane encapsulation itself. It avoids the need of using two EHs to achieve the goal. Using two EHs not only bloats the header size but also requires cumbersome configurations to the non-SR routers. In either case (SRH or

Hi Giuseppe, would you propose a text that can guide developers and operators through the implementation and deployment of the Alternate Marking in IPv6 and SRv6 scenarios? Perhaps as Operational Considerations? Thank you for pointing out two IOAM specifications. I agree with you that our discussio

Hi WG, I don’t agree with Bruno’s point that “this draft could be better restricted to the SR-replication segment itself, leaving any application/VPN specifics outside the scope of this SPRING document”. As I commented in [8] to the same point, the backing solution of this document is tightly r

Hi Xiao, Thank you for the feedback. As also discussed with Greg, this is a general issue if you want to add on-path information for SRv6 and avoid some limitations with the option header (RFC 9098 and draft-ietf-6man-eh-limits). I think that, for SRv6, a more robust way can be to integrate the

Hi Greg, I think that this draft for SRv6 can recommend to integrate AltMark into SRH, since this can mitigate the issues. But the choice between DOH and SRH TLV should be a more general decision taken by the WGs. Indeed, the same question involves all the on-path telemetry techniques, e.g. for
