Embodiment Construction

[0053] Such as figure 1 As shown, in one embodiment, a data message transmission method includes the following steps:

[0054] Step S110, receiving the first data packet transmitted after the connection is established.

[0055] In this embodiment, the first data packet received is the first data packet transmitted after the current connection is established. The first datagram is transmitted via the TCP protocol.

[0056] Such as figure 2 As shown, in one embodiment, before the above step S110, it also includes:

[0057] In step S210, a connection is established, and the option field in the data message is established through the connection, and negotiation is performed.

[0058] In this embodiment, in order to transmit the data message between the data sending end and the data receiving end, the data sending end will establish a connection with the data receiving end, and send a negotiation message to the data receiving end to determine whether the data receiving end agr...

Abstract

The invention provides a data message transmission method and system. The data message transmission method includes: receiving a first data message transmitted through built connection; extracting the length of a datum to be transmitted from an option domain of the first data message; obtaining receiving waiting time of the data message and transmitting message losing information according to the receiving waiting time and the length of the datum to be transmitted; and receiving the data message which is retransmitted according to the message losing information. The data message transmission system comprises a receiving module, an extracting module and a control module. The receiving module is used for receiving the first data message transmitted through built connection; the extracting module is used for extracting the length of the datum to be transmitted from the option domain of the first data message; the control module is used for obtaining receiving waiting time of the data message and transmitting message losing information according to the receiving waiting time and the length of the datum to be transmitted; and the receiving module is further used for receiving the data message which is retransmitted according to the message losing information. By adopting the data message transmission method and system, network bandwidth waste is reduced.

Description

technical field [0001] The invention relates to network transmission technology, in particular to a data message transmission method and system. Background technique [0002] With the rapid development of the Internet, the Long Fat Network (Long Fat Network) is becoming more and more common, and there are more and more data-sensitive network applications. For example, video applications and audio applications will occupy a large amount of network resources, thereby making The congestion phenomenon in the network is becoming more and more serious, and the application of traditional transmission methods will not be able to meet the current network transmission requirements. [0003] The TCP protocol (Transmission Control Protocol), that is, the transmission control protocol, is currently a widely used data transmission protocol to provide end-to-end reliable data transmission. However, when the transmission control protocol is used to transmit the data message, if the data me...
