Description
Technical field
The invention belongs to the data processing field of network service ICP/IP protocol, particularly based on data processing method, system and the receiving terminal for digital television of TCP.
Background technology
At present two-way, bimodulus or completely in IPTV (Intemet Protocol Television, the Web TV) set-top box, all to use the ICP/IP protocol stack, wherein the agreement overwhelming majority of transport layer uses Transmission Control Protocol.TCP is Connection-oriented Protocol, and it creates a virtual connections between two TCP.TCP is at the control of transport layer use traffic and error control mechanism.TCP provides full-duplex service, i.e. at one time two-way flow of data.Each TCP has the buffer memory of transmission and receives buffer memory, and both direction can send message segment.TCP is Reliable transport protocol, and it checks with affirmation mechanism whether data arrive safely and intactly.Defined byte number, Sequence and Acknowledgment Number among the TCP and guaranteed whether the data of send and receive are complete; TCP provides flow control, and how many data the receiving terminal control transmitting terminal of data can send, and this is to make the receiving terminal paralysis for fear of a large amount of data; For reliable service is provided, TCP realizes error control mechanism, although error control is regarded a message segment as the data cell of error detection occurs, error control is byte-oriented; TCP is provided at the congestion control in the network, and the data volume that transmitting terminal can send not only will be subjected to the control (flow control) of receiving terminal, but also will be decided by the Congestion Level SPCC of network.
Generally, the client and server end of TCP is the reliability that the data sequence number by message segment and the affirmation of replying number guarantee the TCP transmission.Because Internet Transmission middle distance and several factors can cause the data transmitted destroyed or lose, because TCP is reliable transmission, therefore the missing data bag carries out the re-transmission of message segment by the error control mechanism of TCP, namely working as a message segment receives damage, is dropped or has been delayed, will retransmit this message segment, receiving terminal will be recombinated the message segment that receives in this case, to guarantee the integrality of packet.In the process of carrying out the message segment restructuring, tcp protocol stack can store the message segment of discontinuous sequence number first, and the sequence number that sends the message segment of losing subtracts one affirmation sequence number, wish that server can resend out with the message segment of losing, in case the message segment that client has been lost before having received, will send immediately the sequence number of the continuous message segment of its maximum of receiving, when not having data to retransmit, the affirmation sequence number packet that client sends will send according to the time rule of replying timer of TCP.But at server end, because the phenomenon of data re-transmission having occured before, therefore the protocol stack of server end can be thought the non-constant of current network conditions, in order to prevent continuing to have loss of data and too much re-transmission to cause network congestion, it will slow down the transmission speed of message segment, in case server has slowed down speed, the data message section that receives in client has so just reduced accordingly, if send the data flow of program by the front end Ethernet, will occur by data volume that Ethernet receive obviously reducing the phenomenon that when broadcast program card occur or pause at IPTV set-top box end this time.

Described slow processes module also is used for when judging that described message segment occured to retransmit, the immediate answer sign is set, and data are appended to receive after the buffer memory, also judging whether needs the data that send or needs immediate answer, is the message segment sequence number that then sends immediately the data of client or reply affirmation.
As shown in Figure 4, the data handling system based on TCP of the present embodiment, it comprises server end, and receiving terminal for digital television, server end is connected IP network with receiving terminal for digital television and connects.Wherein, receiving terminal for digital television comprises above-mentioned data processing equipment based on TCP.
The operation principle of the present embodiment below is described in detail in detail:
At first, the TCP message segment that receiver module reception server end sends, if the verification of check message segment and whether correct correct, is then searched the socket handle that is complementary with this message segment again; If incorrect, then send RESET (reset and connect) message and abandon the message segment of receiving to server end, return and continue to receive next message segment.After finding the socket handle that is complementary, judge again whether this socket handle is empty, if be not empty, judge again then whether this socket handle is waited for the message segment that receives to this message segment, if enter fast processing flow, if not, enter slow processing flow.If the socket handle is empty, then send the RESET message to server end, abandon the message segment of receiving, return and continue to receive next message segment.
In general, server end is to send by the order of message segment, and for example, sending sequence number first is 01 message segment, and sending sequence number is 02 message segment again, namely with 01,02,03,04, the order of 05...... sends.Client also judges sequentially with this whether message segment of receiving is waiting for the message segment of reception so.
When certain message segment transmission lag, when damaging or abandoning, will retransmit this message segment, for example, No. 03 message segment delayed delivery, client has been received message segment 01 and No. 02, next No. 03 message segment of reception that needs, but owing to reasons such as Network Transmission Delays, client is not received message segment No. 03, but receive message segment No. 04, client can think that this No. 04 message segment is not the message segment that wait for to receive so, then enters slow processing flow, extract the data load in the message segment after, data are joined in the restructuring formation, and immediate answer ACKNOW sign is set and retransmits sign, the server end of announcement need retransmit message segment No. 03 immediately, like this, after receiving and reply, server end will retransmit this message segment, thereby server end can send correct message segment fast, thereby when the IPTV set-top box receives the program that sends by Ethernet, program is play more smooth.
Then, server end retransmits No. 03 message segment, because client has been received message segment No. 04, therefore, No. 03 message segment is not that the socket handle is waited for the message segment that receives, so, still enter slow handling process, extract the data load in the message segment after, judge that the message segment order is correct, and re-transmission occured before retransmitting the sign judgement, and immediate answer ACKNOW sign is set again, namely the server end of announcement need send message segment No. 05.
Then, server end sends No. 05 message segment, client judges that this message segment is that the socket handle is waited for the message segment that receives, enter fast processing flow, data load is non-vanishing in No. 05 message segment, and when spatial cache can hold, client appends to the data load in this message segment in the reception buffer memory of socket handle, wakes receiving process up.Owing to before re-transmission occuring, therefore, immediate answer ACKNOW sign is set again, send immediately acknowledged sequence number to server end, namely the server end of announcement sends No. 06 message segment, and then cancellation retransmits and indicates.
Then, server end sends No. 06 message segment, client judges that this message segment is that the socket handle is waited for the message segment that receives, enter fast processing flow, data load is non-vanishing in No. 06 message segment, and when spatial cache can hold, client appended to the data load in this message segment in the reception buffer memory of socket handle, wakes receiving process up.Cancel owing to retransmitting sign, therefore, do not retransmit before judging, so, delayed response DELACK sign is set, cancellation retransmits sign again, is about to retransmit the state that flag bit is set to " not retransmitting ".
Hence one can see that, and the present invention suitably arranges the sign of immediate answer by in fast processing flow and slow processing flow, so that when data transmission exception, terminal is the notification server end immediately, makes it send correct data, thereby has accelerated data transmission bauds.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
