Hi Alberto,

thank you for that update. I fully support the move of the PubSub draft RFC to 
the standard track, since it is required by the ICAO standardization process of 
the Air Traffic Network (ATN) IPS.  As some of you know, the feature is used in 
the ATN IPS system to improve the performance of the GB-LISP mobility solution 
and enhancing the reachability of aircrafts via multiple A/G datalinks. (see 
GB-LISP presentation at IETF 113)
I am also pleased to find this scenario partially reflected in the deployment 
experience chapter. We have validated one available Pub/Sub implementation for 
this purpose in 2022 in a large international research project and we would 
like to provide the following feedback:
Please provide more detailed information about the explicit unsubscribe 
operations – e.g., what happens if the XTR has a valid subscription to a less 
specific EID-prefix but would like to unsubscribe for a more specific 
EID-prefix?

[AR] The unsubscribe operation is described in a paragraph at the end of 
Section 5, but the example you describe might be needed to be covered 
explicitly. I’m thinking we could update the unsubscribe paragraph as follows 
to describe this case, let me know what you think.

OLD >
The following specifies the procedure to remove a subscription. 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. In this case, 
the Map-Server MUST send the Map-Notify to the source RLOC of the Map-Request.

Map-Server MUST remove the subscription state for that xTR-ID. In this case, 
the Map-Server MUST send the Map-Notify to the source RLOC of the Map-Request. 
If the Map-Server has received this Map-Request for an EID-Prefix without an 
explicit subscription for the xTR-ID but covered by a less-specific EID-Prefix 
for which a subscription exists for that xTR-ID, the Map-Server SHOULD stop 
publishing updates for the more-specific EID-Prefix to that xTR, until the xTR 
explicitly subscribes to the more-specific EID-Prefix.

Thanks and br
Bernhard Haindl

Hi all,

This new version should include all the feedback received prior to the most 
recent comments from Padma (we’ll address those in -11). Version -10 is also 
the first one on Standards Track and includes a section on deployment 
experiences. Please take a look and let us know any feedback you might have.

Thanks!
Alberto
