| 0x01 | 0x02 |
If authentication is passed through, equipment then to be upgraded sends an information frame to described PC, and the content of the data load part of this frame can be as shown in table 5:
The content sample table of the data load part of table 5 information frame
| First | Second byte | 20 bytes | Four bytes | |
| 0x01 | 0x03 | The Transmission Control Protocol head | The size of remaining upgrade file |
If equipment to be upgraded and described PC have carried out carrying out the UDP transmission again after the TCP transmission, the UDP transmission has been failed again then, then just no longer comprises the Transmission Control Protocol head part in the data load content of this information frame of follow-up transmission, and example is as shown in table 6:
The content sample table of the data load part of table 6 information frame
| First byte | Second byte | Four bytes |
| 0x01 | 0x03 | The size of upgrade file |
After described PC receives this information frame, select to the employed agreement of the remaining upgrade data of device transmission to be upgraded according to predetermined strategy, by selected agreement this information is sent to equipment to be upgraded then, the form of the data division of this Echo Frame is shown in table 7 and table 8:
Table 7 uses the data load content sample table partly of the Echo Frame of Transmission Control Protocol
| First byte | Second byte | A byte |
| 0x01 | 0x04 | 0x00 |
Table 8 uses the data load content sample table partly of the Echo Frame of udp protocol
| First byte | Second byte | A byte | Four bytes | Four bytes |
| 0x01 | 0x04 | 0x01 | Source udp port number | Purpose udp port number |
When using udp protocol certainly, can also adopt more special TFTP agreement to transmit.
If described PC will use TCP to proceed file transfer with equipment to be upgraded, then PC is changed to normal transmission state to local tcp state earlier, and according to the content of described information frame each field of TCP message is filled, begin then to carry out communication with equipment to be upgraded.
If described PC will use UDP to proceed file transfer with equipment to be upgraded, then PC uses included port of described Echo Frame and equipment to be upgraded to carry out communication, carries out the transmission of upgrade file then.When carrying out the udp protocol transmission, PC can partly add a unique sequence number in the beginning of the data message that is transmitted, and for example this sequence number increases progressively since 0.PC is waited for its sequence number of being received of device replied to be upgraded after sending a data message, if do not receive the answer of equipment to be upgraded, PC can retransmit this data message, retransmits three failures and then can disconnect connection.Certainly on equipment to be upgraded, can set in advance continuation and send the number of times that transmission is asked, for example surpass three times and just no longer proceed down to PC.Equipment to be upgraded can also dispose to the other PC that sets in advance and send the transmission request.
