Dear Job,

Hi working group,

In recent mail threads the concepts of "Hosted RPKI" and "Delegated
RPKI" came up, but as mentioned by Tim and Rubens, another flavor also
exists! A "hybrid" between Delegated and Hosted, informally known as
"publish in parent" (aka RFC 8181 compliant Publication Services).

There are multiple benefits to the general RPKI ecosystem when RIRs and
NIRs support RFC 8181:

   * Resource Holders are relieved from the responsibility to operate
     always online RSYNC and RRDP servers.

   * Reducing the number of Publication servers reduces overall
     resource consumption for Relying Parties. Consolidation of
     Publication Servers improves efficiency and is generally
     considered advantageous.

   * Helps avoid "reinventing the wheel": it might be better to have a
     small group of experts build a globally performant and resillient
     infrastructure that serves everyone, rather than everyone building
     the 'same' infrastructure.

Other RIRs and NIRs are also working on RFC 8181 support. RFC 8181 is
relatively new so it'll take some time before we see universal
availability.

   APNIC (available): https://blog.apnic.net/2020/11/20/apnic-now-supports-rfc-aligned-publish-in-parent-self-hosted-rpki/
   ARIN (planned): https://www.arin.net/participate/community/acsp/suggestions/2020/2020-1/

Is implementing RFC 8181 support something RIPE NCC should add to the
https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-planning-and-roadmap ?

What do others think?

Kind regards,

Job

Thanks for bringing this up. 
Please be aware that the roadmap you mentioned just shows the roadmap for the current quarter and not for a longer period. 
If you see something missing there, it does not mean that we don’t intend to work on it, just (probably) not in the current quarter, unless it is urgent of course. The reason why we chose to publish a quarterly roadmap, is to facilitate discussions on our priorities with this working group. 
This is exactly why I’m very pleased that you brought up this topic (potential work item). We can always add new functionality to future roadmaps. In about a week, we will publish our roadmap for Q4. 

In the past, RFC8181 support (Hybrid RPKI, publish in parent, repo-as-a-service) has been asked from RIPE NCC by a few community members, for example by Benno Overeinder at RIPE82 in the routing-wg session:https://ripe82.ripe.net/archives/steno/47/ 

I look forward to seeing a discussion here on this topic to find out if there is a broader interest.

Kind regards,

Nathalie Trenaman
