What is the correct MTU setting for the gnuradio UDP Source block for a payload size less than the default...

The gnuradio UDP Source block has a default Payload Size of 1472. The documentation indicates



"payload_size : UDP payload size by default set to 1472 = (1500 MTU - (8 byte UDP header) - (20 byte IP header))"



My C client program sends packets of 16 bytes to the gnuradio udp source once every second.



Should I set the MTU value to 16?



Thank you.

          No, the Payload Size refers to the maximum packet size that can be handled by the block. However, the block then handles your 16 byte as a stream, so if you like to keep this packet form additional steps are required.

          • Depends on your application. If the 16-bytes group is significant for you, you may group them in a vector, or declare the start of each packet with a tag. If it it does not matter, let them as a stream.
