Embodiment Construction

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0058] One of the main ideas of the invention may include:

[0059] The sender determines the amount of buffered data in the network communication link according to the network bandwidth and network delay. According to the sending window notified by the receiver, combined with the buffered data amount, the amount of data sent by the sender can be determined, and the sender follows the The amount of data to send, and send a data packet to the rece...

Abstract

Embodiments of the present invention provide a data message sending method, device and equipment, the method includes: according to the network bandwidth and network delay, determining the amount of cached data in the network communication link within the network delay; The window and the cached data amount determine the amount of data to be sent; according to the amount of data to be sent, a data packet is sent to the receiving end. Through the embodiments of the present invention, the continuity of data reception is guaranteed, and the quality of data transmission is improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, and more specifically relates to a data message sending method, device and equipment. Background technique [0002] TCP (Transmission Control Protocol, Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication protocol, which provides a full-duplex byte stream service. [0003] In the prior art, when the sending end and the receiving end perform data transmission based on the TCP protocol, the sending end usually sends the data message according to the size of the sending window notified by the receiving end. According to the TCP protocol, the sending window cannot be larger than the receiving window size of the receiving end. The sending window specifies the amount that can be sent, and the receiving window specifies the amount of data that the receiving end can cache. [0004] However, the inventor found in the proc...
