A simple Lua script for Wireshark to dissect WTP packets in UDP datagrams.
WTP is a reliable transport protocol built on top of UDP. It is defined in an assignment for the course EECS 489: Computer Networks at the University of Michigan, Ann Arbor.
The script assumes UDP port 1817 (UMich's founding year) is being used for communication with the receiver. I used this after looking around port registries and not finding anything of value using this port, but it can be changed in the last line of the script.
Add this script to Wireshark's "Personal Lua Plugins" directory (can be found under About > Folders)
Set the display filter to umichwtp and start capturing packets
on the appropriate interface.
