Protocol dependencies

• UDP: MIOP is over UDP

• GIOP: MIOP encapsulates GIOP protocol over UDP

Example traffic

Wireshark

The MIOP dissector is partially functional. It can show all information about MIOP packet header fields and it groups all MIOP packets into a MIOP collection. Also it can show the subsequent GIOP details for the first MIOP packet of a MIOP packet collection. The MIOP dissector listen in any UDP port .
