Problems solved by technology

However, if an error occurs during data writing, the data can only be rewritten
Therefore, the time for data retransmission will be prolonged, and it will also increase the load of network bandwidth
In addition, the same data file must not only be reloaded from the client, but also retransmitted within the local end, which will also result in longer data retransmission time and increase the load on network bandwidth

Embodiment Construction

[0023] The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.

[0024] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the...

Abstract

The invention discloses a transmission device and a transmission system for splitting data. By the aid of the transmission device and the transmission system, transmission errors caused when data files are split or are written into disk arrays can be prevented. The transmission device comprises a receiving module, a memory module, a distributed file device and a processing module; the receiving module is used for receiving the data files of a client; the memory module is connected to the receiving module and is used for storing the data files; the distributed file device is used for storing target files; the processing module is connected with the receiving module, the memory module and the distributed file device and generates a plurality of internal queues, each internal queue is used for storing path information of the corresponding data file, the data files are split into a plurality of split sections by the processing module according to the path information of the internal queues, and the split sections are parallelly read by the processing module and are written into the target files in the distributed file device.

Description

technical field [0001] The present application relates to a data transmission system, in particular to a data segmentation transmission device and system. Background technique [0002] With the rapid growth of network traffic, many services that were not easy to implement in the past can also be easily completed. For example: broadband upload multimedia files (multimedia file). Due to the massive transmission will still affect the load on the local side. Therefore, the known multimedia local end also has a bandwidth management (Bandwidth Manager) function. The local end can reduce the amount of data transmission at the same time through bandwidth distribution or caching. [0003] In addition, the transmission method further combines multiple physical disks, so that data can be written to the disks synchronously. However, in the prior art, the way of writing data to the disk is to write the data synchronously from the source end to the local end. The local side will stor...
