Hi Don,

The files are 4500 bytes each. They consist of binary data. The overall
transfer rate is low, on the order of 1 KB/s or less.

What "caveats of UDP-based protocols" are you referring to? Are you
referring to things such as out-of-order packets and no error-checking?

I am not really knowledgable on the lower layers of TCP/IP.
