Re: [lisp] WG Last Call for draft-ietf-lisp-pubsub

Hi Eliot, all,

The procedure to unsubscribe is covered by the following:

   If the Map-Request only has one ITR-RLOC with AFI = 0 (i.e., Unknown
   Address), the Map-Server MUST remove the subscription state for that
   xTR-ID.

We discussed among the authors back in 2017 whether the procedure should allow to select the EIDs for which an ITR can unsubscribe, but the agreement was to keep the spec simple. Hence the above text.

Cheers,
Med

Objet : Re: [lisp] WG Last Call for draft-ietf-lisp-pubsub

Just poking my nose in here, this is a cool draft. I say, go for it.  Depending on implementation, it may address the very problem I was attempting to solve with NERD: that first dropped packet.

I have one small suggestion and a question:

The suggestion:

It would be useful to discuss what statistics should be kept when experimenting.  Specifically: number of subscribes (prior to or after the first time one saw an EID), the number of map updates over time (I’m betting there’s a lot of stability out there, but that’s just me), number of subscribers.

The question:

How would an xTR UNsubscribe from mapping notifications?  I would imagine this would amount to a new map request that clears the N bit for appropriate EID-Records?
