Embodiment Construction

[0022] figure 1 It is the main flow chart of the data transmission method of the embodiment of the present invention. With reference to this figure, the method mainly includes:

[0023] 101. According to the instruction information of the first data point where the task data transmission is interrupted, determine that the second data point in the transmitted data before the first data point is used as the starting point for retransmitting the task data;

[0024] Specifically, task data can be for files, entire directories, databases, or emails, etc.; the transmission can be one-way transmission, and one-way transmission can use a one-way transmission channel, and there can be one or more nodes in the one-way transmission channel. Some devices in the node can be one-way transmission devices; the indication information can be data transmission control information; the relationship between the first data point and the second data point can be as follows figure 2 as shown, fig...

Abstract

The embodiment of the invention relates to a data transmission method. In the method, according to the indication information of a first data point where the transmission of task data is interrupted, a second data point in transmitted data prior to the first data point is determined as a starting point for the retransmission of the task data so as to retransmit the task data from the starting point. In addition, the embodiment of the invention also provides a data transmission device. The embodiment of the invention can realize broken-point continuingly-transferring in data transmission so as to improve the quality of service of a system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and device. Background technique [0002] With the development of network communication technology, the technology applied in the field of data transmission is changing with each passing day, which provides a technical basis for solving various network emergencies. [0003] In the existing data transmission process, the communication system is prone to problems such as node power failure and failure. These problems may cause data transmission interruption, thereby greatly reducing the data transmission efficiency, reducing the system service quality, and reducing the user's data transmission service. satisfaction. Contents of the invention [0004] The technical problem to be solved by the embodiments of the present invention is to provide a data transmission method and device, which can realize resuming transmission from breakpoints in data transmi...
