Dear all,

The meeting minutes of today's meeting are attached below. You may also check the github page to follow up previous meetings.

Minutes: (Note taker: Kai) Focus: Preparation of IETF 117 and recharter conversation

- Action items:
  -  Richard will set up the meeting with CATS and send an invite to the mailing list
  -  Identify the leader of the BGP community document. Come up with two concrete proposals.(Richard volunteers)
  -  Chunchi will engage with Ayoub to work on the item.

  -  Meeting with CATS on how to coordinate between Luis's document and CATS's document(s)
     -   Metrics related to computing are defined in both working groups and need to be coordinated
     -   Adrian will have 5 min to present at ALTO during IETF 117
     -   Richard suggests having a working session with CATS members earlier before IETF
     -   Sabine: The CATS draft does not list the metrics. CATS is looking at low-level metrics for traffic steering, not necessarily the same way in ALTO.
     -   Sabine: Both approaches are complementary. It is necessary to define the intersection and the (difference). For intersected metrics, there might be inter-dependency between the two WGs. For unrelated metrics, both WG can proceed on their own.
  -  IETF 117 agenda
     -   Jordi: Focus on priorities. 1 or 2 topics in IETF:
         -   Suggestion by Med: motivation, problem description and charter item proposal
         -   Deployment catalyst.
     -   Deployment catalyst discussion:
         -   Richard: A large amount of successful protocols are about HOW not WHAT. Deployment catalyst is difficult because it is missing HOW in ALTO.
         -   Qin: (Agree with the argument) To promote the ALTO deployment, focus on integration and operation.
         -   Jordi suggests targeting this as an informational document
     -   BGP community/BGP-LS &amp; ALTO:
         -   Qin: Propose BGP community for ALTO map and BGP-LS integration with ALTO. Discuss the problem space and motivation.
         -   Qin: Luis might be overloaded and another person is needed to lead the efforts
         -   Richard volunteered to take the responsibility
     -   Discussion on integration with compute
         -   Qin: Concern is that IETF does not have protocols to connect computation.
         -   Jordi: Two elements: 1. How to get information. 2. How to expose that information. There is a need to understand the space with some informational documents.
         -   Richard: Protocol is connecting the dots: you have something already and define how things can be done. But no dots for computing in IETF now.
         -   Discussion by Richard, Jorid and Qin suggests an investigation of existing standards on exposing compute (as an informational document) is highly useful
         -       initial sources: COINRG, CATS (in progress), ETSI, 5G,
         -       Jordi suggested having a survey of use cases to obtain a list of required metrics
         -       Qin suggested the boundary between ALTO and CATS is that CATS defines the metrics and common abstractions of computing while ALTO defines how to connect/query the metrics (?)
         -   Jordi suggested focusing on new elements that weren't covered in IETF 116 for this topic
      -  Green networking
         -   Richard: A large concern is energy consuming. Will that be a good starting metric to work on?
         -   Qin: IETF already has this energy mib (?) IETF has a side meeting. Green networking has been discussed in nmrg.
      -  Security
         -   Qin: The security part by Fujitsu is still in the research stage. Luis has prepared some slides to discuss security consolidation. Potential discuss on using JOSE object for ALTO.
         -   Chunchi will take the lead for integration ALTO with JOSE (?) and engage Ayoub.
