UDP (User Datagram Protocol) based matchable strategy data transmission method

Abstract

The invention discloses a UDP (User Datagram Protocol) based matchable strategy data transmission method. Strategies such as the message transmission mode, the message compression strategy, the message retransmission times, the message timeout, the single package sending length, the sending window number and the active message delay which are required by the transmission are abstracted to form a strategy configuration file and the strategy information is read from the strategy configuration file and the strategy configuration is performed before the data transmission. When the used network transmission channel environment is changed, a user does not need to modify software codes again and only needs to modify part of the strategies in the strategy configuration file to meet the actual use demand, the data transmission can adapt to bandwidth and narrow-band channels and stable and high-delay channels, the point-to-point and point-to-multipoint data transmission can be implemented, and the software use is flexible and simple due to the facts that only a transmission strategy of a sending end need to be modified and the automatic strategy matching is achieved through a receiving end.

Description

technical field [0001] The invention relates to a network data transmission technology, which belongs to the technical field of network transmission. Background technique [0002] At present, the TCP / IP protocol system is a widely used network communication standard. Among them, UDP is a connectionless protocol with high efficiency but unreliable; TCP is a connection-oriented protocol with high reliability but low efficiency. Due to the contradiction between real-time and reliability of the TCP and UDP transport layer protocols, coupled with the complexity of the actual network environment, it is impossible to directly use the existing UDP or TCP protocol, so it must be redesigned according to the needs of business transmission. An application layer transport protocol with service transport characteristics. The TCP protocol has been widely used in network programming, which can realize error-free transmission of data, but at the cost of complex transmission control and lar...

Problems solved by technology

At present, it is difficult to find a universal and reliable transmission method based on UDP, which cannot be directly used in various projects; in a specific network application environment, it is often necessary to encode the transmission method according to the characteristics of the environment, which cannot be simply adjusted The transmission strategy can meet the requirements of new transmission channels, and it cannot achieve the strategy matching between the sender and the receiver only through single-end strategy adjustment, which is not conducive to the rapid development, rapid adjustment and maintenance of software
