Re: 20240924: latest 7 day summary NOAAPort Gap stats

Jim et al,

On 16 Sept, NOAA did a channel realignment on the SBN to help with actualization of channel priorities.  I am not attempting to be patronizing for everyone on this email . . . but a "channel" is a discrete PID configured on the satellite modem, and is used to partition data.

For the sake of nomenclature, in this context, the "Satellite Broadcast Network - SBN" is the NOAAPort and NWWS data streams.  So SBN means both.

That, within itself, was not the cause, but the primary contractor was waiting to get this particular realignment completed before doing some round-robin on the ground station uplink.  Which happened the following day around 1340Z . . . and was followed by a couple of hours of messiness as the last time this was attempted, it exhibited the exact behaviour we are seeing now . . . but reduced this time.

The symptom of the issue is individual SBN frames are sent out of sequence.  I have checked across three different SBN receiving software packages - the one with LDM, the one I wrote years ago, and Jose Nieves's nbsp . . . and they all *expect* the frames to arrive in sequence, and when they don't, the assumption is made that a gap has occurred between the last frame and the current frame when those sequence numbers are not serial.  I also know, for those of us old enough to remember, that NGIT's acqserver . . . the original AWIPS SBN receive software . . . also expected the frame numbers to occur in sequence.

For the LDM noaaportIngester users, this can be seen with the reference to a "Retrograde packet number":

20240925T142859.903396Z noaaportIngester[4393]      productMaker.c:pmStart:1249         ERROR Missing fragment in sequence, last 5/7650698 this 7/7650698
20240925T142859.903436Z noaaportIngester[4393]      productMaker.c:pmStart:522          WARN  Retrograde packet number: previous=10457646, latest=10457645, difference=4294967295

The last time this happened with a change at the uplink, all channels were affected.  This time, however, only four channels on the SBN are impacted with this problem:

EXP - PID 106
GRE - PID 108
NOPT - PID 104
NWWS - (separate RF/modem) PID 201

The good news is the last of the ""Retrogrades" that occurred on NWWS was 22 Sep at 0036Z.  So, maybe it is fixed?  The last one on EXP was 24 Sept at 1918Z, and GRE had an event 25 Sept at 0333Z, and NOPT 25 Sept at 1428Z (the Retrograde example above).

It may be getting fixed . . . as I don't see it happening on NWWS any longer, and the last one on EXP was yesterday . . . but that is why no one is getting "0" frame loss since the 17th.

Before you write/call NOAA/NCF, it does appear that things are getting sorted, so maybe sit on it a day or so longer.  I have been diligent about bringing it up often since it started, and like the rest of us, I know they have a lot on their plates.

There was a time we routine had zero gaps for a week or two and then when we did it was next to nothing. Not that the numbers are huge and I have do not have a way to look into it but are we all missing the same frames as in it is on the send side or what is going on now that we routinely have the 200-900 dropped frames a day?  Anyone have any insight into what is going on more than myself who at this point has only looked at these nightly digest of numbers?
