UDP Source and Sink = "Straight" UDP

GNU Radio

Hello,

I just wanted to confirm that the UDP Source and Sink blocks just “chop
up”
the data to fit inside the payload buffer (who’s size is determine by
the
PAYLOAD_SIZE attribute) and do not handle “extra” things in the
application
layer like reordering of packets received out of order or resending
packets
in the event that data is dropped.

Stated differently, the UDP Source and Sink are “vanilla” UDP and don’t
have any additional features added in the application layer, correct?

Thanks in advance for the help.

Hi Peter,
that’s an easy one to answer:

correct?
yes; refer to gr-blocks/lib/udp_sink_impl.cc .

Best regards,
