User Datagram Protocol (UDP)
UDP is only a thin layer, and provides not much more than the described UDP port multiplexing.
Are you looking for Lightweight UDP? Then visit UDP-Lite.
XXX - add a brief description of UDP history
XXX - Add example traffic here (as plain text or Wireshark screenshot).
The UDP dissector is fully functional.
There are two statistical menu items for UDP available: Statistics/Endpoints which contains a tab showing all UDP endpoints (combination of IP address and UDP port) and Statistics/Conversations, which contains a tab showing all UDP conversations (combination of two endpoints).
(XXX add links to preference settings affecting how UDP is dissected).
Example capture file
XXX - Add a simple example capture file. Keep it short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.
A complete list of UDP display filter fields can be found in the display filter reference
