3.3.2.2 ProTrace Full Decoding Panel

When the user selects a payload event in the Events Panel or a balloon from the Event Diagram, the corresponding message is displayed fully decoded in the Full Decoding Panel. This view explains every byte of the selected message.

The ProTrace Full Decoding Panel is further divided into two panels. The first panel shows the payload bytes of the messages. The second panel displays the Message Header and all AVPs decoded into a readable format. It shows every field of the header and AVP. Each field of the message header and AVP is displayed on separate lines.

The detailed decoding list has certain columns:

• Offset (An offset address of the field from the beginning of the payload. The Version field of the Message Header has an offset 0)
• AVP/Field Name
• Value and description (Value and possible description)
