TFTP data
This message flow simulates a TFTP file transfer over UDP and is used as a subflow in the TFTP RRQ message flow.
The subflow begins when the mainflow generates a Start Subflow event. The Client Port and Server Port defined in the message flow are used for the TFTP transfer.
-
The server sends a 128-byte packet as block number 1, and the client acknowledges with the block number.

NOTE: This message flow is designed to be used as a subflow and should not be used as a mainflow. |
Modifying the Message Flow
The packet header is represented with red in the diagram above, and the data content (Zs) is shown in black. The size of the data content can be increased by using filler data or an imported file. The headers should not be modified unless you are familiar with the packet formats.
