Optionally, progress of embodiment of the present invention retransmission process includes:
To the data packet that needs retransmit, retransmitted in such a way that interval retransmits.
It should be noted that preset format of the embodiment of the present invention, interactive interface, monitoring process etc. can be with reference to related skills
Existing implementation design design realizes that this will not be repeated here in art.
The embodiment of the present invention carries out the transmission of data packet through the above way, fails 3 times with continuous verification and continuously retransmits
Then terminate transmission operation more than 3 times.It examines after actual measurement, the embodiment of the present invention wants high compared with the relevant technologies efficiency of transmission.
The transmission of data of the embodiment of the present invention can realize the transmission of data packet, window design principle and sliding window by window
Mouth design principle is similar, and window of the embodiment of the present invention is realized in application layer, and in the window of working node side setting, the present invention is implemented
Example is known as source window, and source window is mainly used for recording data transmission state, and working node transmits 5 data packets each time,
Therefore setting source window size is 5, and window signal is as shown in table 1, each window serial number 0~4:
| 0 | 1 | 2 | 3 | 4 |
Table 1
When the embodiment of the present invention sends data packet for the first time, working node can continuously transmit 5 data packets, it is assumed that packet serial number point
Not Wei 1~5, and data packet serial number is respectively placed in 0~No. 4 window, maintenance node is waited to send confirmation message.
For source window, there are following information in window structure to save data transmission state value, are respectively:
The index of next data packet sequentially to send in the window, index range 0-4；
Next packet numbers sequentially to send；
The index of smallest sequence number data packet to be answered in the window such as, index range 0-4；
Retransmission flag；Wherein, FALSE expression does not retransmit, and TRUE indicates to retransmit.
Assuming that the state in table 2 of window:
| 0 | 1 | 2 | 3 | 4 |
| 15 | 11 | 12 | 13 | 14 |
Table 2
In table 2: the first behavior window indexes, the data packet serial number stored in the second behavior window, it is assumed that window, which indexes, is
The window hypothesis that the call number that overstriking is shown is 2 receives confirmation message,
Data transmission state is as shown in table 3 at this time:
| The index of next data packet sequentially to send in the window | 1 |
| Next packet numbers sequentially to send | 16 |
| The index of smallest sequence number data packet to be answered in the window such as | 1 |
| Retransmission flag | TRUE |
Table 3
11 number packets can be retransmitted in these cases gives maintenance node.
The confirmation for the 13 number packets that maintenance node side is sent is had received at this time, and same show by overstriking indicates, it is assumed that
Window is as shown in table 4:
| 0 | 1 | 2 | 3 | 4 |
| 15 | 11 | 12 | 13 | 14 |
Table 4
Data transmission state is as shown in table 5 at this time:
| The index of next data packet sequentially to send in the window | 1 |
| Next packet numbers sequentially to send | 16 |
| The index of smallest sequence number data packet to be answered in the window such as | 1 |
| Retransmission flag | FALSE |
Table 5
Under the data transmission state shown in table 5, No. 11 packets will not be retransmitted and give maintenance node, interval of embodiment of the present invention weight
The mode of biography.Similarly if when what is received next time is 14 number packet, it will retransmit No. 11 packets and give maintenance node.It is assumed that this
The secondary confirmation for receiving 11 number packets, then window is shown with data transmission state difference as shown in table 6 and table 7:
| 0 | 1 | 2 | 3 | 4 |
| 15 | 16 | 17 | 18 | 14 |
Table 6
| The index of next data packet sequentially to send in the window | 4 |
| Next packet numbers sequentially to send | 19 |
| The index of smallest sequence number data packet to be answered in the window such as | 4 |
| Retransmission flag | FALSE |
Table 7
After receiving the confirmation of 11 number packets, by the update of window data transmission state information to No. 4 index positions, simultaneously
It continuously transmits 16,17 and 18 number packets and gives maintenance node.
The window size of the corresponding maintenance node of design of the embodiment of the present invention is 5, its data received is mainly cached, to orderly
File is written after receiving.For window, it is used to save data transmission state there are following data in window structure, is respectively:
Next data packet serial number sequentially reached；
The index of next data packet sequentially reached in the window；
Indicate the number of data packets (not including out-of-order data packet) of received in-order in window, value range 0-5；
Assuming that window is in state shown in table 8:
| 0 | 1 | 2 | 3 | 4 |
| 15 | 11 | 12 | 13 | 14 |
Table 8
Note: in table 8, the first behavior window index, second is classified as the data packet serial number stored in window, and overstriking font receives
Data packet, data transmission state is as shown in table 9 at this time:
| Next data packet serial number sequentially reached | 11 |
| The index of next data packet sequentially reached in the window | 1 |
| The number of data packets of received in-order in window | 0 |
Table 9
In the state of shown in the table 9, maintenance node sends the confirmation of 12 number packets to working node.
Assuming that the 13 number packets that working node is sent are had received, 11 institute of window and data transmission state such as table 10 and table
Show:
| 0 | 1 | 2 | 3 | 4 |
| 15 | 11 | 12 | 13 | 14 |
Table 10
Table 11
Under under above-mentioned data transmission state, file will not be written in 12 and 13 number packets, because of 11 number Bao Wei
It receives.It is assumed that this receives 11 number packets, window and data transmission state as shown in table 12 and table 13:
| 0 | 1 | 2 | 3 | 4 |
| 15 | 16 | 17 | 18 | 14 |
Table 12
Table 13
After receiving the confirmation of 11 number packets, the update of window data transmission state information is carried out, all by 11,12 and 13 packets
Orderly is written in file, and waits No. 14 packets.
In carrier class networking, if there is Network Isolation, it can be used present invention method to the multinode list of isolation
