Embodiment Construction

[0045] The method of the present invention is divided into two processes of sending and receiving.

[0046] Send large data according to the principle of "unpacking-compression-unpacking", that is, first split a large data packet into multiple smaller data packets, and then compress them; if the compressed data packet is still too large , then perform the splitting operation again.

[0047] When receiving large data, follow the principle of "merge-decompress-merge", that is, first merge the split compressed packages to form a complete compressed package, then decompress all the compressed packages, and finally uncompress the decompressed data again Combined to form one big data package.

[0048] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] figure 2 The sender process is given, including the following steps:

[0050] A. Split a super large data packet according to a certain size (suc...

Abstract

The invention relates to a method for transmitting mass data based on a UDP protocol. The method comprises a sending method and a receiving method. As the data transmission of Ethernet is limited by packet size, the situation occurs that a data packet is unsuitable for transmission or even can not be transmitted occurs due to overlarge data size. The method for transmitting mass data based on the UDP protocol effectively combines a compaction algorithm and a data packet splitting method, sends mass data according to a principle of unpacking-compaction-unpacking and receives mass data according to a principle of uniting-decompaction-uniting. The sending end flow and the receiving end flow relate to a private protocol of a compaction / non-compaction data packet. The method has clear flow, concise parameters of a protocol format, strong extendibility and wide application range, can be effectively applied to transmitting mass data based on the UDP protocol and improve the efficiency and reliability of transmission.

Description

technical field [0001] The invention relates to the field of Ethernet communication, in particular to a large amount of data transmission method based on the UDP protocol and using a compression algorithm. Background technique [0002] The UDP protocol is the abbreviation of the English User Datagram Protocol, that is, the User Datagram Protocol. It is a connectionless transport layer protocol in the ISO reference model. It provides operation-oriented simple and unreliable information transmission services. A network application that transfers data between them. [0003] UDP does not provide a reliable mechanism, flow control, and error recovery functions for the IP protocol. UDP is a connectionless protocol. The sender and receiver do not establish a connection before transmitting data. When the sender wants to transmit, it simply grabs the data from the application and throws it on the network as quickly as possible. At the sending end, the speed at which UDP transmits d...
