3. IETF New Work summary

  - Applications and Real-Time

    ADD - Applications Using DoH - Discussions at the DoG WG and a side
    meeting at IETF104 suggest there appears to be significant interest
    in examining in the operational aspects of DoH deployment,
    particularly in operator and enterprise networks. This lead to
    the creation of the ADD mailing list where some of these issues
    have been discussed. The proposed BoF intends to establish if
    there are sufficient potential work items and enough interest at
    the IETF to justify the creation of a new Working Group which
    would focus on these topics.

  - General

    NETRQMTS - IETF Meeting Network Requirements - NOT WG Forming - The
    IETF meeting network has a long history of pushing beyond the bounds
    of normal event networks. This BoF will gather community input on
    the network requirements for IETF meetings, including prioritization
    and the resource implications associated with those requirements.

  - Internet

    NONE
    
  - Operations and Management

    MOPS - Media OPerationS - The purpose of this BoF is to highlight 
    the many existing video activities that are leveraging IETF protocol 
    work, identify gaps in IETF work and/or areas of incompatibility 
    with video technology development efforts being carried out 
    elsewhere, and identify a core group of IETF participants working on 
    video activities across the IETF’s technology areas.

  - Routing

    NONE
    
  - Security

    CACAO - Collaborative Automated Course of Action Operations (CACAO)
    for Cyber Security - To defend against threat actors and their 
    tactics, techniques, and procedures, organizations need to manually
    identify, create, and document prevention, mitigation, and
    remediation steps.  These steps when grouped together into a course
    of action (COA) / playbook are used to protect systems, networks,
    data, and users.  The problem is, once these steps have been created
    there is no standardized and structured way to document them, verify
    they were correctly executed, or easily share them across
    organizational boundaries and technology stacks.  The intent is to
    charter a working group that will create a standard that implements
    the playbook model for cybersecurity operations.

    LAKE - Lightweight Authenticated Key Exchange - Constrained
    environments using OSCORE in network environments such as NB-IoT,
    6TiSCH, and LoRaWAN need a 'lightweight' authenticated key exchange 
    that enables forward security. 'Lightweight' refers to resource
    consumption, measured by bytes on the wire, wall-clock time to
    complete, or power consumption; and the amount of new code
    required on end systems which already have an OSCORE stack. 

  - Transport

    LOOPS - Local Optimizations on Path Segments - Performance Enhancing
    Proxies (PEPs) have been used to improve performance over paths with
    links of varying quality, often peeking (and poking!) into the
    transport protocol.  Encryption is putting an end to this practice.
    At the same time, more powerful network nodes are becoming 
    available, making it more viable to trade processing power in 
    network nodes against path quality.  Transport protocols and their 
    implementations are moving towards playing better with forwarding 
    node functions such as ECN marking and AQM.

7. Adjourn

Post-meeting addendum from Pascal Thubert:

From: "Pascal Thubert (pthubert)" <pthubert@cisco.com>
Subject: Re: [ieee-ietf-coord] Draft Minutes from the 2019-06-19 IETF-IEEE 802 Coordination Meeting
Date: June 24, 2019 at 7:56:43 AM PDT

Dear all:
 
As a follow up on the discussion of SAVI and IEEE 802.11. 
 
Please note that I published draft-thubert-6man-ipv6-over-wireless to 
explain better the issues with the SAVI draft and how RFC 8505 family 
solves them.

Please note that as an implementor of SAVI in my company’s Wi-Fi gear, I 
have a first-hand view on these issues. In the introduction you’ll find 
the following:
 
“
   Discovering peer addresses by snooping the IPV6 ND protocol as
   proposed for SAVI [I-D.bi-savi-wlan] was found to be unreliable.  An
   IPv6 address may not be discovered immediately due to a packet loss,
   or if a "silent" node is not currently using one of its addresses,
   e.g., a node that waits in wake-on-lan state.  A change of state,
   e.g. due to a movement, may be missed or misordered, leading to
   unreliable connectivity and an incomplete knowledge of the set of
   peers.
 
   Wireless ND (WiND) introduces a new approach to IPv6 ND that is
   designed to apply to the WLANs and WPANs types of networks.  On the
   one hand, WiND avoids the use of broadcast operation for Address
   Resolution and Duplicate Address Detection, and on the other hand,
   WiND supports use cases where Subnet and MAC-level domains are not
   congruent, which is common in those types of networks unless a
   specific MAC-Level emulation is provided.
 
   To achieve this, WiND applies routing inside the Subnets, which
   enables MultiLink Subnets.  Hosts register their addresses to their
   serving routers with [RFC8505].  With the registration, routers have
   a complete knowledge of the hosts they serve and in return, hosts
   obtain routing services for their registered addresses.  The
   registration is abstract to the routing protocol, and it can be
   protected to prevent impersonation attacks with [I-D.ietf-6lo-ap-nd].
 
   The routing service can be a simple reflexion in a Hub-and-Spoke
   Subnet that emulates an IEEE Std 802.11 Infrastructure BSS at Layer
   3.  It can also be a full-fledge routing protocol, in particular RPL
   [RFC6550] that was designed to adapt to various LLNs such as WLAN and
   WPAN radio meshes with the concept of Objective Function.  Finally,
   the routing service can also be ND proxy that emulates an IEEE Std
   802.11 Infrastructure ESS at Layer 3.  WiND specifies the IPv6
   Backbone Router for that purpose in [I-D.ietf-6lo-backbone-router].
 
   More details on WiND can be found in Section 4.1.

“
 
I’m happy to discuss the draft on this list but would rather we copy 
6MAN since I plan to present the draft there.
 
All the best,
 
Pascal
