The speed of
NOAAPort bandwidth being disseminated has reached a cap somewhere up the line.
To explain what I am seeing, please notice this graphic:
The chart is
an automated Munin chart. In this instance, the inbound traffic is via NOAAPort
only, and the outbound traffic is what is disseminated via this ‘relay’ to its
associated downstream boxes.
In the box
noted as “A” we see a ‘flatline’ region of inbound traffic somewhere in the
neighborhood of 25mb/sec, with small peaks to ‘exactly’ 30mb/sec (as noted on
the “max” notation in the bottom right). At this time, the outbound traffic to
downstream servers shown above the box displays no flatline, so we know it is
not an internal limit of the router, but that router is a 1gb router, so it
shouldn’t be a problem. This peak occurred as shown in the timestamp
yesterday.beginning around 6am.
In the box
noted as “B” we see a flatline for last night through this morning running for
pretty much the entire day fluctuating between 22-24mb/sec peaking again at the
30mb/sec max.
If memory
serves, on our old settings NOAAPort was maxed out at 30mb/sec, but the upgrade
was supposed to be to 100mb/sec. As the chart shows, the flatline / capping on
the receiving end is not a physical limitation of the hardware, therefore the
limit must be within the satellite itself, or the upstream feed to the
satellite.
Hope everyone
has a great weekend
 cheers,
