Hello Behcet :)long time! Many thanks for your review!
Sure.
I placed proposed changes in GitHub at https://github.com/raw-wg/raw-architecture/commit/0b13749fa529a4282732d8c6fc411689ce75b4a7Please see below:
Summary:
This draft reliable and available wireless architecture in the context of
deterministic networking or DetNet, i.e. the draft
complements DetNet for wireless.
Overall, it is a good document, involving huge amount of work, especially I
liked Section 3.1.1.1 3rd and 4th paragraphs explaining wireless single point
of failure.
However it has a number of typos and issues.
Major issues:N/A
Minor issues:
It seems like on DetNet there is currently ongoing research and development
involving TSN in IEEE 802.1 and IETF. I suggest that the document makes it
clear that Sections 4 and 5 describe roughly a design which needs to be
implemented together with TSN as part of link layer.
Makes sense; First paragraph of section 4.3 becomes:"4.3. RAW and DetNet
RAW leverages the DetNet Forwarding sub-layer and requires the
support of OAM in DetNet Transit Nodes (see figure 3 of
[DetNet-ARCHI] for the dynamic acquisition of link capacity and state
to maintain a strict RAW service, end-to-end, over a DetNet Network.
In turn, DetNet and thus RAW may benefit from / leverage
functionality such as provided by TSN at the lower layers."Nits/editorial comments:
Issues:
Many typos:
Sec. 2 controled -> controlled
2.1.6 massage & 2.1.6 massaged -> message
3.2 recieve -> receive
The assumption us -> is
Along a alternative paths -> along alternative paths
5.1 fucntion -> function
donePlease check, possibly reword:
3.1.1.1 2nd par.
edited as:"
IP Routers leverage routing protocols to reroute to alternate routes
in case of a failure. When links are cabled through the same
conduit, they form a shared risk link group (SRLG), and share the
same fate if the conduit is cut, making the reroute operation
ineffective. The same effect can happen with virtual links that end
up in a same physical transport through the intricacies of nested
encapsulation. In a same fashion, an interferer or an obstacle may
affect multiple wireless transmissions at the same time, even betweendifferent sets of peers.."Through the games of encapsulationremoved "games"
3.2 OODA list Point 2
may also generate knowledge and wisdom such as a trained model for link quality
predictionSorry what should I do here ?
I think you meant machine learning or ML models here, so I suggested making it specific.
On Fig. 6 is there or not tunneling on strict RAW over Detnet?
No, that's the difference with fig 7 where RAW may traverse an uncertain area, in which case packets may arrive too late and be discarded.
Isn't it true that in the core network there is a tunnel (like MPLS tunnel) somewhere? I suggested mentioning it here, just a suggestion.
5.1
SD-WAN
MPLS-TP undefined
DoneAgain, many thanks for your review. Please let me know if more changes are in order.
Please see above.

all the best,--Pascal
