[Discuss-gnuradio] handling bursty data

[Rahul Dhar]

In HDTV streams, there is a large quantity of data that is always there.
Each block, therefore, always has data to send to the next block, and
the scheduler happily keeps iterating over the flowgraph.  In a data
network, we have bursty traffic.  Are there any complications because of
this?  I'm thinking of buffering along the Tx path, specifically.  Will
data that is buffered in the host stay there until the next time the
sink block is run, or does everything written to the USRP Tx eventually
make it to the Tx d'card, even if the Tx sink block is never run again?
I'm seeing behaviour that could either be that not all data is
transmitted, or maybe my synchronization sequence isn't long enough.
Either way, it seems that there needs to be a "critical mass" of data
being transmitted continuously before recovery works (based on the
fsk_rx/tx example: it doesn't work sending a file in non-looping mode,
at least for me)

Thanks,
