Reliable and Available Wireless (RAW) provides for high reliability and
availability for IP connectivity over a wireless medium. The wireless medium
presents significant challenges to achieve deterministic properties such as low
packet error rate, bounded consecutive losses, and bounded latency. RAW extends
the DetNet Working Group concepts to provide for high reliability and
availability for an IP network utilizing scheduled wireless segments and other
media, e.g., frequency/time-sharing physical media resources with stochastic
traffic: IEEE Std. 802.15.4 timeslotted channel hopping (TSCH), 3GPP 5G
ultra-reliable low latency communications (URLLC), IEEE 802.11ax/be, and L-band
Digital Aeronautical Communications System (LDACS), etc. Similar to DetNet, RAW
will stay abstract to the radio layers underneath, addressing the Layer 3
aspects in support of applications requiring high reliability and availability.

While DetNet solutions apply to both wireless and wired, there has been recent
industry interest for wireless applications which were not initially included
in the DetNet use cases. One critical application is Aeronautical Data
Communications. The Aeronautical standards work on a physical layer and data
link layer for data communications is reaching maturity and there is
significant interest in developing an IP connectivity solution.

In the interests of providing timely solutions for these newly identified
industry applications, RAW’s focus will be on identifying use cases and
requirements for these new applications. RAW will solicit input on deployment
plans, requirements, and operational practices (including security and privacy
aspects) for these newer industrial applications. RAW’s primary focus is on
identifying areas where the DetNet adaptation to wireless networks requires
additional supporting mechanisms. The RAW Working Group will also examine the
applicability of other existing IETF work, e.g., DLEP. The RAW Working Group
will provide input to the DetNet Working Group, MANET Working Group, and other
IETF Working Groups, and cooperate in reviewing solutions to RAW’s identified
deployment problems. RAW is not chartered to work on a solution, if solution
work is needed in addition to the DetNet solution work or other existing
solution work in the IETF, it will be coordinated on where the work will be
done. In the event that RAW is chosen for the work, the Working Group will

The RAW Working Group is planned to be a short timeframe (12-18 months) Working
Group to quickly address these newer industry applications. The initial
milestones will be comprised of Informational documents: Use Cases,
Requirements, Architecture/Framework Aspects for a Wireless Network, and an
Evaluation of Existing IETF Tools and Gap Analysis. The documents may exist
individually or on a git repository. The Use Case document may consist of one
or more documents to allow users/operators the opportunity to provide
comprehensive deployment plans for these new (to IETF) technologies. The group
will closely coordinate with the DetNet and MANET Working Groups. The work
produced by this group may be of interest to other SDOs, 3GPP, IEEE, and the
Aeronautical industry. No formal co-ordination is anticipated with these other
groups at this time.
