super good news!

let me see what I can do regarding TSCH.

> Dear all

> All hands on the bridge, the WG forming BoF was approved yesterday!

>
>
> For memory the BoF request is here:
> https://trac.tools.ietf.org/bof/trac/wiki, inlined below.
>
>
>
> And it points at the draft charter ​
> https://trac.tools.ietf.org/bof/trac/wiki/RAW
>
>
>
> We have already one chair named for the BoF, Erik Nordmark from IAB. We
> need to prepare the agenda and reread the proposed charter.
>
>
>
> There was some concern that we are not overlapping with IEEE. It would be

> *RAW* BoF request
>
> Name: Reliable and Available Wireless (RAW)
>
> Description: Due to uncontrolled interferences, including the self-induced
> multipath fading, deterministic networking is difficult to achieve on
> wireless links. The radio conditions may change -way- faster than a
> centralized routing paradigm can adapt and reprogram, in particular when
> the controller is distant and connectivity is slow and limited. RAW
> separates the routing time scale at which a complex path is recomputed from
> the forwarding time scale at which the forwarding decision is taken for an
> individual packet. RAW operates at the forwarded time scale. The RAW
> problem is to decide, within the redundant solutions that are proposed by
> the routing, which will be used for each individual packet to provide a
> DetNet <https://trac.tools.ietf.org/bof/trac/wiki/DetNet> service while
> minimizing the waste of resources. A RAW solution would consist of a set of
> protocols that evaluate the media in real time and another that controls
> the use of redundancy and diversity attributes that are available along the
> path.
>
> RAW intersects with protocols or practices in development at the IETF as
> follows:
>
>    - MANET defines DLEP that can be leveraged at each hop to derive
>    generic radio metrics (e.g., based on LQI, RSSI, queueing delays and ETX)
>    on individual hops
>    - OAM work at DetNet <https://trac.tools.ietf.org/bof/trac/wiki/DetNet>
>    observes the state of MPLS and IPv6 pseudowires in the direction of the
>    traffic. RAW needs feedback that flows on the reverse path and gathers
>    instantaneous values from the radio receivers at each hop to inform back
>    the source and PREOF relays so they can make optimized forwarding
>    decisions. The work named ICAN may be related
>    - SPRING and BIER define in-band signaling that influences the routing
>    when decided at the head-end on the path. There's already one RAW-related
>    draft at BIER, more may follow.
>    - RAW will need new in-band signaling when the decision is
>    distributed, e.g., required chances of reliable delivery to destination
>    within latency. This signaling enables relays to tune retries and
>    replication to be met.
>    - CCAMP defines protocol-independent metrics and parameters
>    (measurement attributes) for describing links and paths that are required
>    for routing and signaling in technology-specific networks. RAW would be a
>    source of requirements for CCAMP to define metrics that are significant to
>    the focus radios.
