Abstract
The invention relates to the technical field of communication, in particular to a system and a method for improving the reliability of user datagram protocol (UDP) connection. Shortcomings are overcome, the system and the method are reliable, and transmission speed is higher. The system comprises at least two client terminals which are interconnected through a network. Each client terminal comprises a transceiver module, serves as a transmission client terminal when transmitting data, and serves as a receiving client terminal when receiving the data. According to the system and the method for improving the reliability of the UDP connection, the reliability of the UDP connection is effectively enhanced by a confirmation step, so that the UDP connection is higher in transmission speed and reliability.
Description
Technical field
The present invention relates to communication technical field, in particular to a kind of system and method that improves the UDP connection reliability.
Background technology
Transmission control protocol UDP (User Datagram Protocol) agreement belongs to transport layer protocol.It is towards disconnected agreement, does not namely connect with the other side, and directly Packet Generation is gone over.UDP is applicable to once only to transmit low volume data, the applied environment not high to reliability requirement.In general UDP is corresponding is the application that reliability requirement is low, transmission is economic, and UDP do not provide reliability to connect, and does not guarantee after Packet Generation is gone out to arrive at the destination, and causes the packet loss phenomenon.
Summary of the invention
The present invention overcomes defects, provides a kind of reliable and transmission speed to improve faster the system and method for UDP connection reliability.
The technical scheme of the system of raising UDP connection reliability of the present invention is such: it comprises at least two client terminals, client terminal is by the network interconnection, client terminal all comprises transceiver module, for sending client terminal, client terminal is to receive client terminal when receive data to client terminal when sending data.
Optimally, it also comprises service terminal, sends client terminal by service terminal and is connected the client terminal connection.
The method of raising UDP connection reliability of the present invention comprises following steps:
A: send client terminal and send data, send packet to service terminal;
B: service terminal is received packet, and package forward to receiving client terminal, is generated simultaneously one and confirms bag, sends to the transmission client terminal;
C: when the reception client terminal is received packet, generate one and confirm bag, then send to service terminal;
D: after service terminal receives the confirmation bag, will confirm that bag sends to the transmission client terminal, and finish the transmitting-receiving task, if when sending client terminal behind the step B and not receiving the affirmation bag of service terminal in the interval at the appointed time, will enter step e; If when service terminal does not receive the affirmation bag that receives client in the interval at the appointed time behind the step C, will enter step F;
E: send client terminal packet is resend to service terminal, when reaching the sending times of setting, service terminal will generate connection failure information, sends to the transmission client terminal;
F: service terminal resends packet to receiving client, reach the sending times of setting after, service terminal will generate connection failure information, sends to the transmission client terminal.
Optimally, the setting-up time of the technical program is set to 0.3-1.0 second.
Optimally, the sending times of the technical program is set to 3-5 time.
As the another kind of implementation method of said method, directly connect between reception client terminal and the transmission client terminal, and do not pass through service terminal:
A: send client terminal and send data;
B: receive client terminal and receive packet, generate simultaneously one and confirm that bag sends to the transmission client terminal; If when sending client terminal and not receiving the affirmation bag that receives client terminal in the interval at the appointed time, will enter step C;
C: send client terminal packet is resend to receiving client terminal, when reaching the sending times of setting, send client terminal and will generate connection failure information, stop to send.
Optimally, the setting-up time of the technical program is set to 0.3-1.0 second.
Optimally, the sending times of the technical program is set to 3-5 time.
The system and method for raising of the present invention UDP connection reliability is confirmed step by one, has effectively strengthened the reliability that UDP connects, and make UDP connect not only transmission speed than very fast, and reliability is also relatively good.

Embodiment
Embodiment 1:
It comprises at least two client terminals UDP connected system of the present invention, and client terminal is by the network interconnection, and client terminal all comprises transceiver module, and for sending client terminal, client terminal is to receive client terminal when receive data to client terminal when sending out the transmission data.It also comprises service terminal, sends client terminal by service terminal and is connected the client terminal connection.
The operating process of the technical program is such: send client terminal and send data, send packet to service terminal; Service terminal is received packet, and package forward to receiving client terminal, is generated simultaneously one and confirms bag, sends to the transmission client terminal; When the reception client terminal is received packet, generate one and confirm bag, then send to service terminal; After service terminal receives the confirmation bag, to confirm that bag sends to the transmission client terminal, finish the transmitting-receiving task, if when sending client terminal and not receiving the affirmation bag of service terminal in the interval at the appointed time, sending client terminal resends packet to service terminal, when reaching the sending times of setting, service terminal will generate connection failure information, sends to the transmission client terminal; When if service terminal does not receive the affirmation bag that receives client in the interval at the appointed time, packet is resend to receiving client, reach the sending times of setting after, service terminal will generate connection failure information, sends to the transmission client terminal.
The time interval of present embodiment is set as 0.3 second, and sending times is set to 3 times.
Embodiment 2:
The difference of present embodiment and embodiment 1 is that the system of the raising UDP connection reliability of present embodiment does not comprise service terminal, receives client terminal and sends the direct point-to-point transmission of client terminal.
The operating process of the technical program is such, sends client terminal and sends data, sends packet to receiving client terminal; Receive client terminal and receive packet, generate simultaneously one and confirm bag, send to the transmission client terminal; If when sending client terminal and not receiving the affirmation bag that receives client terminal in the interval at the appointed time, sending client terminal resends packet to receiving client terminal, when reaching the sending times of setting, send client terminal and will generate connection failure information, stop to send.
The time interval of present embodiment is set as 1.0 seconds, and sending times is set to 5 times.
