RE: [RPRWG] Question on State Table 9.13, Receive Fairness Frame
Fredrik,
I believe that the first item you mention is correct as is. Since the fairRate is FULL_RATE, the sendC indication can indicate any number of hops without effecting the client. And it seems possibly useful to retain the information about where the last congestion point was.

Subject: [RPRWG] Question on State Table 9.13, Receive Fairness Frame
In row 2, when receiving a single choke fairness message from
downstream neighboor, where:
frame.fairRate == FULL_RATE
frame.saCompact != myMacAddress
frame.ri == myRingletID
I.e. a message that that it is ok for the upstream station to increase
its send rate.
Shouldn't also the hopsToCongestion be set to MAX_STATIONS in the last
else (in addition to setting downstreamCongested = FALSE)?
Otherwise the SendC signal sent to the client is whatever the previous
value of hopsToCongestion was...
A definite error in the same row (line 13) is that rcvdSa is set to
frame.sa. It should be set to frame.saCompact as fairness messages
does not have a sa field (why did fairness frame have a different
header format again ;)...
Best Regards,
Fredrik
