Embodiment Construction

[0041] The embodiment of the present invention provides a method for transmitting data packets, a client and a server, for the client to send the first target data packet and the first redundant packet to the server, the ID of the first redundant packet and the first target data The IDs of the packets are the same, so the probability of packet loss during data packet transmission is reduced.

[0042] In order to enable those skilled in the art to better understand the solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is an embodiment of a part of the present invention, but not all embodiments. All embodiments based on the present invention shall belong to the protection scope of the present invention.

Abstract

The invention discloses a data packet transmission method. Via the method, a client sends a first target data packet and a first redundant packet to a server, the ID of the first redundant packet is the same with that of the first target data packet, and the probability of packet loss of the data packet during transmission is reduced. The method comprises that the client determines the first target data packet to be sent; the client generates the first redundant packet corresponding to the first target data packet, the ID of the first redundant packet is the same with that of the first target data packet, and a type identification of the first redundant packet is the different from that of the first target data packet; the client sends the first target data packet and the first redundant packet to the server; the client receives a response packet back fed by the server; and according to type identifications of the response packet, the first redundant packet and the first target data packet, the client determines a reception result of the server.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for transmitting data packets, a client and a server. Background technique [0002] User Datagram Protocol (UDP, User Datagram Protocol) is a connectionless transport layer protocol in the OpenSystem Interconnection (OSI) reference model, which provides transaction-oriented simple and unreliable information transmission services. UDP has the disadvantages of not providing data packet grouping, assembling and sorting of data packets, that is to say, after the message is sent, it is impossible to know whether it has arrived safely and completely. [0003] UDP is used to support network applications that need to transfer data between computers. Numerous client / server network applications, including network video conferencing systems, need to use the UDP protocol. UDP communication is a connectionless transmission, and the protocol level does not guarantee the safe arrival of dat...
