Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.Should be appreciated that described herein being embodied as
Example, only in order to explain the present invention, does not limit the present invention.
As it is shown in figure 1, the embodiment of the present invention provides a kind of data transmission method based on TCP, including:
S11, sending ending equipment is during carrying out data re-transmission to receiving device, and statistics retransmits message
Transmission total bytes；
S12, described sending ending equipment obtains the total word of reception of the duplicate message that described receiving device receives
Joint number；
S13, data retransmit after terminating, at described reception total bytes more than or equal to described transmission total byte
In the case of number, sending ending equipment confirms that network is the most congested, and the message before using data to retransmit sends parameter
Send message.
The data transmission method based on TCP that the embodiment of the present invention provides, sending ending equipment is to receiving terminal
During equipment carries out data re-transmission, it is possible to statistics retransmits the transmission total bytes of message, and obtains described
The reception total bytes of the duplicate message that receiving device receives, data retransmit after terminating, in described reception
Total bytes, more than or equal in the case of described transmission total bytes, illustrates the message sink of all repeating transmission
Having received, this packet receiving probability explanation network is the most congested, so the message before using data to retransmit
Send parameter and send message.So, in tcp data transmitting procedure, even if there occurs that data retransmit,
Sending ending equipment also can further determine whether really with receiving total bytes by comparing transmission total bytes
There occurs network congestion, thus avoid message transmission parameter and unnecessarily reduce, be effectively increased data and pass
Defeated speed and bandwidth availability ratio.
Optionally, it is that some parameters that sending ending equipment is carried out when message sends are arranged that message sends parameter, can
To include congestion window and Slow start threshold etc..Wherein, congestion window is at a RTT ((Round-Trip
Time, round-trip delay) in the number-of-packet that can at most send, be sending ending equipment according to transmitting terminal according to
The Congestion Level SPCC of network is preset.Slow start threshold then represents that sending ending equipment message sends message rate and increases
A long flex point.Specifically, initial TCP can send big after connection establishment success in network
The packet of amount, so easilys lead to router spatial cache in network and exhausts, thus occur congested.Cause
This newly-established connection can not send packet the most in a large number, and progressively can only increase according to network condition
Add the data volume of transmission every time, to avoid the generation of congestion phenomenon.Sending ending equipment sends the speed of message and increases
Long flex point is Slow start threshold.
General, in the case of network condition is good, transmitting terminal TCP can send parameter with higher message,
Such as congestion window and Slow start threshold etc., carry out message transmission.But when protocol stack enters Fast retransmission or time-out
During re-transmission, sending ending equipment will be considered that and there occurs that network congestion sends parameter with less message and carries out data
Retransmit.But in the case of a lot, and non-real there occurs network congestion, therefore reduce message and send parameter and very may be used
Can be unnecessary.In order to differentiate the most really to there occurs network congestion further, sending ending equipment can be first
Record the message before data retransmit and send parameter, to the data stream sending in data retransmission processes and receiving
Amount compares.
Optionally, in step S11, sending ending equipment during carrying out data re-transmission to receiving device,
Statistics retransmits the transmission total bytes of message and comprises the steps that sending ending equipment is carrying out data weight to receiving device
During biography, the byte number of all re-transmission messages is added up.Such as, in an enforcement of the present invention
In example, sending ending equipment needs to retransmit packet 3, packet 4, packet 5 to receiving device, if
The size of packet 3 is 1024 bytes, and packet 4 size is 4096 bytes, and packet 5 size is 516
Byte, then, in this secondary data retransmission processes, the transmission total bytes retransmitting message is
1024+4096+516=5636 byte.
Above, sending ending equipment has been added up in a secondary data retransmission processes, the total word retransmitting message of transmission
Joint number.And the total bytes of the duplicate message that receiving terminal is received, sending ending equipment can pass through receiving terminal
The reception message of equipment feedback obtains.Concrete, in step s 12, sending ending equipment obtains institute
The reception total bytes stating the duplicate message that receiving device receives comprises the steps that
Described sending ending equipment receives the reception of described receiving device and confirms message, and described reception confirms message
In carry the homing sequence number of the duplicate message that described receiving terminal receives and end sequence number；
Described sending ending equipment according to the difference of described end sequence number Yu described homing sequence number, determine described in connect
Receive the byte number of message corresponding to confirmation message；
Each described byte number receiving message corresponding to confirmation message is added up, to obtain by described sending ending equipment mutually
Take described reception total bytes.
Illustrating, in one embodiment of the invention, TCP receiving terminal, can be to sending out after receiving message
Sending end equipment feedback reception confirms message, such as ACK message.The sending ending equipment ACK to each arrival
The most whether packet check carries D-SACK, and (Duplicate Selective Ackowledgement repeats choosing
Select confirmation) option.Wherein, D-SACK is a kind of SACK option to TCP that RFC2883 proposes
Extension standards, it is allowed to first SACK block at TCP carries rising of the duplicate message that receiving terminal receives
Beginning serial number and end sequence number.If be detected that ACK message carries D-SACK option, then extract
The homing sequence number of the duplicate message that the receiving terminal carried in D-SACK option receives and end sequence number, two
Person subtracts each other the byte number obtaining the duplicate message that receiving terminal receives, and the repetition fed back by each ACK message
Message byte number is added to the byte number variable that D-SACK confirms.This process lasts till that this secondary data retransmits
Terminate, thus obtain the reception total bytes of the duplicate message that receiving device receives.
It should be noted that the process that described data retransmit can be from Fast retransmission start to described soon
Speed retransmits and terminates, and namely sending ending equipment is from continuously receiving preset times (such as 3 times) repeat ACK
And start express delivery and retransmit, terminate only to exit recovery state to this Fast retransmission；Or from once surpassing
Shi Chongchuan starts to described Retransmission timeout to terminate, and namely enters from the retransmission timer time-out of sending ending equipment
Retransmission timeout state rises, and terminates only to exit recovery state to this Retransmission timeout.
In step s 13, after a secondary data re-transmission terminates, total bytes can be received and send total word
Joint number compares, and is more than or equal to send total bytes if receiving total bytes, this re-transmission is described
Message sink all have received at least 2 times, network condition is good, does not occur congested, it is not necessary that
Turn down message according to the counter-measure of network congestion and send parameter, before therefore can recovering to use data to retransmit
The parameter that sends the message of record continues to send message, is effectively increased data transmission bauds and the bandwidth profit of network
By rate.

305, the recovery after whether transmitting terminal has had logged out Fast retransmission or Retransmission timeout this moment is judged
State.If so, step 306 is performed, if it is not, perform step 309；
306, compare byte number cumulative for D-SACK and retransmit the byte number that message is accumulative, if D-SACK
(multiple proxy server in network, is there is in cumulative byte number more than or equal to the byte number retransmitting message accumulative
Time it is possible that situation about being more than), illustrate that network is the most congested, perform step 307, otherwise perform step
309；
307, congestion window and Slow start threshold are reverted to the value recorded before, revises the most incorrect
Fall window；
308, byte number cumulative variations will be retransmitted and D-SACK will confirm that byte number cumulative variations resets, will note
Record congestion window and Slow start threshold valid tokens are set to illegal, revise congested for D-SACK next time
Window flow prepares.
