Embodiment Construction

[0060] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0061] When the sender periodically sends data to the receiver, the total number of packets sent to the receiver in one cycle may or may not be the same as the total number of packets successfully sent to the receiver. When the current network resources are insufficient, the data sent by the sender to the receiver may experience data delay or data loss. The total number of data packets at the receiving end is not equal; when the curre...

Abstract

The embodiment of the invention discloses a data transmitting method and device, and relates to the technical field of network communication. Data are periodically transmitted. The method includes the steps that a data package transmitting interval of an nth period is determined; in the nth period, data packages are transmitted according to the determined data package transmitting interval; the data package transmitting interval of the nth period is determined through the following steps that the total number NumCT of transmitted data packages in an (n-1)th period and the number NumCS of the data packages which are successfully transmitted to a receiving end in the period are counted; whether the total number NumCT and the number NumCS are equal or not is judged; if the total number NumCT and the number NumCS are not equal, the total number NumNT of the data packages to be transmitted in the nth period is estimated according to the total number NumCT and the number NumCS; according to the total number NumNT and preset period duration, the data package transmitting interval of the nth period is calculated. By the adoption of the scheme, when the data are transmitted, the data transmitting speed can be adjusted according to the current network state, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data sending method and device. Background technique [0002] At present, network data transmission is generally based on UDP (User Datagram Protocol, User Datagram Protocol). Among them, UDP is a connectionless transport layer protocol in the network reference model, which provides transaction-oriented unreliable transmission services. . [0003] In the prior art, when network data transmission is performed based on UDP, data is generally transmitted at a fixed data transmission rate, regardless of current actual available network bandwidth and the like. However, when the data transmission rate is high and the actual available network bandwidth is narrow, due to the limited transmission capacity of the current network, data transmission delays or packet loss may occur, resulting in poor user experience. Contents of the invention [0004] The embodiment of the...
