>> 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

>> the forwarding time scale at which the forwarding decision is taken for an

>> 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.
