Dear all

 

The slides for the P-DAO discussion at IETF 109 are availabl= e here:

 

https://datatracker.ietf.org/doc/slides-109-roll-dao-proje= ction/

 

There are a number of open questions that we starting discus= sing, and would need to progress on the list.

Some of them were expressed on the list, e.g., from Huimin S= he. I’d like to progress on them all with individual threads.

The questions are:

 

  1. Li= fetime Unit: could we use a different unit for P-DAO?
  2. How to differentiate a P-DAO from a normal DAO in a local instance; n= ew flag?
  3. Make P-DAO bidirectional?
  4. Who sends the PDR? Does it have to be the ingress? If it was= egress it could propose a TrackId from its namespace. Else could the ingress be the root?
  5. Maintaining the = sibling state. Should we have text on using RFC 8505 there?
  6. Whether ingress and egress are listed in NPO? Today they are bo= th, ingress to indicate the packet source in case of encapsulation and for SRH-6LoRH compression reference and egress to build the full SRH-6= LoRH. Note that the ingress must consume the first entry and use it as sour= ce.
  7. Track in Track vs. SR Header reload models, = see slides

 

Let me open threads to follow up.

 

Keep safe
