Abstract

The embodiment of the invention discloses a data transmission method and equipment, which are used for solving the problem that transmitting-end equipment cannot determine whether related applications of receiving-end equipment are about to be in an unavailable state or not, so as not to be able to provide an effective policy to ensure that a data packet reaches the receiving-end equipment within survival time as much as possible. The method can be executed by the transmitting-end equipment, and comprises the following steps: adjusting a data transmission policy under the condition it is determined that N continuous first data packets have sending timeouts, N being an integer greater than 1.

Description

technical field

[0001] The embodiments of the present application relate to the communication field, and in particular, to a data transmission method and device. Background technique

[0002] The availability of communication services is an important service performance requirement indicator for many automation function applications, especially for applications with deterministic business flows. In the industrial environment, many automation function applications have high communication service availability requirements, such as mobile control, and its communication service availability requirements are as high as 99.999999%.

[0003] In the actual application process, when the receiving end device does not correctly receive the data packet sent by the sending end device within a specific time (such as survival time, survival time), it will cause the (automation function) application of the receiving end device to become unavailable state.

[0004] However, for the sending...
