Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
Such as the schematic flow sheet that Fig. 1 is the TCP transmission method in one embodiment, the TCP transmission method of figure, including following
Step：
S11：Obtain the message confirmation number of the TCP response messages received by network side；
S12：Obtain the newest confirmation number of server；
S13：If the message confirms number newest confirmation number for being equal to the server, increase the TCP response messages
Duplicate answer count value；
S14：If the duplicate answer count value is equal to predetermined threshold value, TCP response messages pair described in local cache are improved
The transmission priority of the tcp data message answered.
If identification field ACK (Acknowledgment Number) value in the header of tcp data message is 1, it is determined that
The tcp data message is TCP response messages, and the message of TCP response messages confirms number serial number for being corresponding tcp data message
Plus tcp data message data length.The Serial No. 2001 of such as tcp data message, data length is 1000, then for
The tcp data message, the identification field ACK value in the header of tcp data message is 1, and the tcp data message is TCP response reports
Text, and the message confirmation number of the TCP response messages is 3001.In the present embodiment, server is base station TCP server, for protecting
The newest confirmation number of TCP response messages is deposited, the newest confirmation number of server is the newest confirmation of TCP response messages in server
Number.If the message confirms number newest confirmation number for being equal to server, illustrate that the corresponding tcp data message of TCP response messages is needed
Retransmit, then base station increases the duplicate answer count value of the TCP response messages, TCP connections each time have a repetition
Response count value, for representing in a TCP connection, the repetition of the TCP message transmission received in a stage should
Number of times is answered, the size of duplicate answer count value decides whether that trigger data message retransmission is processed, and the duplicate answer count value is
Base station is arranged, and for the number of times that monitoring base station receives same TCP response messages, if such as base station have received message, confirmation number is
1001 TCP response messages 1 time, then be set to 1 by duplicate answer count value, if base station have received message confirmation number for 1001
TCP response messages 2 times, then be set to 2 by duplicate answer count value.
If the duplicate answer count value is equal to predetermined threshold value, illustrate that the TCP response messages duplicate answer repeatedly (can
Can exceed that twice), then the transmission priority of the corresponding tcp data message of TCP response messages described in local cache is improved in base station.
Such as predetermined threshold value is 4 times, if the multiple response count value of the TCP response messages is 4 times, equal to predetermined threshold value, then shows institute
TCP response message duplicate answers 4 times are stated, is a urgent tcp data message, in the local cache of base station, have its normal
Transmission priority, the normal priority that sends usually first uploads the less tcp data message of serial number, then uploads sequence successively
The larger tcp data message of row number.For the TCP response messages that duplicate answer count value is equal to predetermined threshold value, base station will
The transmission priority of the corresponding tcp data message of the TCP response messages is improved, for example, can be by TCP response messages correspondence
The priority of tcp data message arrange higher than the priority for sending other packets in buffer queue, with it is preferential upload it is described
The corresponding tcp data message of TCP response messages.Or the transmission priority of the current tcp data message is improved into a deciding grade and level
Not, one-level is for example improved, to shorten the times waiting for transmission such as the corresponding tcp data message of the TCP response messages.If base station from
The response message that network side is received is not TCP response messages, then do not do above-mentioned process, is sent directly to lateral terminal of eating dishes without rice or wine.
Such as Fig. 2, in one embodiment, if the message confirms number newest confirmation number for being equal to the server, increase
It is further comprising the steps of after the duplicate answer count value of the TCP response messages：
S131：Detect that the corresponding tcp data message of the TCP response messages whether there is in local cache；
S132：If so, will be present in the corresponding TCP for successfully having uploaded of the TCP response messages of local cache
Data message is discharged.
If the message of the TCP response messages confirms that a number corresponding packet is present in local cache, show the TCP
Response message is the message of duplicate answer, will need to upload successful packet and discharge from local cache, while abandoning
The TCP response messages, without the need for being sent to side of eating dishes without rice or wine.So with the load pressure of alleviation local cache, it is to avoid excessive to take locally
The internal memory of caching, is conducive to the quick transmission of other tcp data messages, has saved network bandwidth resources, reduces unnecessary sky
Port transmission.
Such as Fig. 3, in one embodiment, the newest confirmation number of server is obtained afterwards, it is further comprising the steps of：
S23：If the message of the TCP response messages confirms number newest confirmation number for being more than the server, detection is described
The corresponding tcp data message of newest confirmation number of server whether there is in local cache；
S24：If so, then by the newest confirmation number of the server be set to TCP response messages message confirm number, and will
The corresponding tcp data message for successfully having uploaded of newest confirmation number for being present in the server of local cache is released
Put.
For example, the sequence number range for being currently available for the tcp data message of re-transmission is 1001～3001, then server is most
It is new to confirm number to be 1001, if the message of the TCP response messages that base station receives from network side confirms number to be 2001, then illustrate
The message of the TCP response messages confirms number newest confirmation number for being more than server, illustrates the newest confirmation correspondence of server
Tcp data message be successfully uploaded to network side.Then the newest confirmation number renewal of the server is adjusted to TCP and is answered by base station
The message for answering message confirms number, and will be present in that the newest confirmation number of the server of local cache is corresponding successfully to be uploaded
Tcp data message discharged.If the message of the TCP response messages that base station receives from network side confirm number for 1 or
501, then illustrate that the TCP response messages belong to late response message, without the need for carrying out retransmission process by base station, it is forwarded directly to sky
Mouth side, it is ensured that normal TCP connections interaction.Base station discharges the tcp data message of transmission success from local cache, delays
The load pressure of solution local cache, improves the utilization rate of Internet resources, is conducive to the quick transmission of follow-up tcp data message.
Such as Fig. 4, further, the newest confirmation number of the server is set to into the message confirmation number of TCP response messages,
And will be present in the corresponding tcp data message for successfully having uploaded of the newest confirmation number of the server of local cache and released
It is further comprising the steps of after putting：
S241：By the duplicate answer count value zero setting of the TCP response messages；
S242：The corresponding tcp data message of the TCP response messages is sent to terminal.
The message for judging the TCP response messages confirms number newest confirmation number for being more than the server afterwards, illustrates institute
State that the corresponding tcp data message of TCP response messages is only requested to be transmitted once, be not emergency data, then by the TCP responses
The duplicate answer count value zero setting of message, then sends the corresponding tcp data message of the TCP response messages to terminal.For example,
The newest confirmation number of server is 1001, when the message confirmation number of TCP response messages is 2001, it is seen that the newest confirmation of server
Number corresponding tcp data message is successfully uploaded, base station will the corresponding tcp data message of TCP response messages send to terminal.
The tcp data message replied first is sent directly to terminal by base station, has saved Internet resources, improves data transmission efficiency, is had
Beneficial to the transmission of follow-up tcp data message, it is beneficial to improve operation benefits and Consumer's Experience.
Such as Fig. 5, in one embodiment, the newest confirmation number of server is obtained afterwards, comprise the following steps：
S33：If the message of the TCP response messages confirms number newest confirmation number for being less than the server, send described
The corresponding tcp data message of TCP response messages is to terminal.
After obtaining the message confirmation number and the newest confirmation number of the server of TCP response messages, if the TCP responses
The message of message confirms number newest confirmation number for being less than the server, at this moment directly by the corresponding TCP of the TCP response messages
Data message is sent to terminal, without the need for carrying out retransmission process by base station.The message of such as TCP response messages confirms
2001, the newest confirmation number of server lags behind server most for the corresponding tcp data message of 3001, TCP response messages
It is new to confirm number corresponding tcp data message, belong to late response, the transmission method for the tcp data message of late response,
Without the need for the additional treatments retransmitted by base station, directly the tcp data message transmissions of late response net is saved into terminal
Network resource, improves the efficiency of transmission of backward packet, is conducive to the transmission of follow-up data bag.
Such as Fig. 6, in one embodiment, the message confirmation number of the TCP response messages received by network side is obtained before, bag
Include following steps：
S111：Receive the tcp data message of side upload of eating dishes without rice or wine；
S112：Obtain the serial number of the tcp data message, and according to the order of serial number by the tcp data message
Insertion local cache, for network side Fast retransmission；
S113：The tcp data message is sequentially transferred to into normal priority transmit queue.
Eat dishes without rice or wine side upload tcp data message to base station, base station by eat dishes without rice or wine side upload tcp data message insert in order
In entering local cache, tcp data message is pressed into serial number and data length arrangement, form orderly data message, can be improved
Side of eating dishes without rice or wine uploads the efficiency that tcp data message and base station receive tcp data message.
Such as Fig. 7, in one embodiment, the serial number of the tcp data message is obtained, and according to the order of serial number by institute
It is further comprising the steps of after stating the packet insertion local cache of tcp data message：
S1121：Obtain each tcp data sequence of message number of the tcp data message data stream in local cache；
S1122：If there is out of order, the out of order tcp data message data stream of acquisition in the serial number of tcp data message data stream
Each tcp data sequence of message number；
S1123：The out of order tcp data message data stream is adjusted according to the tcp data header information
It is whole.
Tcp data message data stream includes several tcp data messages, and in local cache, base station is by tcp data message
Packet press serial number order arrangement after, obtain again in order arrangement after, according to each tcp data sequence of message number judge
Tcp data message data stream with the presence or absence of out of order, if there is each tcp data of out of order, out of order tcp data message data stream
Sequence of message number, they are arranged in order again.Again in order arrangement can follow following rule：Second tcp data report
Literary serial number is equal to the length of first tcp data sequence of message number plus first tcp data sequence of message number, the 3rd
The serial number of tcp data sequence of message number is equal to the serial number of second tcp data sequence of message number and adds second tcp data
The length of sequence of message number, by that analogy, does not repeat.
Illustrate below by an instantiation.
For example, each tcp data sequence of message number of out of order section of tcp data message data stream is 1001 (data lengths
1000), 3001 (data lengths 2000), 2001 (data lengths 1000), according to serial number and data length these are rearranged
