File transfer method and system

Abstract

The present invention provides a file transmission method and system. The method includes: the task management center sends task information to the coordination service center; the receiving end of the file transmission reports the receiving end status information to the coordination service center; the coordination service center sends the receiving end status information and The task information is sent to the sending end of the file transfer; if the status information of the receiving end is normal, the sending end sends the file to the receiving end according to the task information; if the status information of the receiving end is abnormal, the sending end cancels sending the file. The file transmission method provided by the present invention coordinates and manages the sending end and the receiving end by adding a coordination service center, and adds a status reporting mechanism, so that the sending end of the file transfer can send the file to the receiving end when the state of the receiving end is normal. File, which effectively solves the problem that when the receiving end is abnormal during the file transfer process, the sending end still sends files and causes file accumulation, and then the problem of resource loss caused by the need to clean up files.

Description

technical field [0001] The present invention relates to the technical field of file transmission, in particular to a file transmission method and system. Background technique [0002] In a content distribution network (CDN), the central server needs to obtain information on the edge servers, such as statistical information on each content access, the available service provision capabilities of the edge servers, etc., for analysis and aggregation, and to achieve network-wide The visual management of resources improves the efficiency of content distribution services and improves the storage utilization of edge servers. The information on the aforementioned edge server, such as its own computing information or log files, is usually transmitted to the central server through file transfer. [0003] In the file transmission process in the prior art, the edge server (ie, the sending end) usually sends files directly to the central server (ie, the receiving end), and the receiving ...

Problems solved by technology

[0004] Since the sender sends files directly and the receiver passively receives files, if there is an abnormality at the receiver, such as a device failure, or the network is disconnected and cannot return to normal in a short time, the sender will continue to try to send files to the receiver until the failure is received The end returns to normal, which will cause the accumulation of files. If there are too many accumulated files, the sender needs additional resources to clean up the accumulated files, which increases the loss of resources.

In addition, when the file transfer task is directly managed on the sending end, if a task needs to change the transfer file or the receiving range, the task needs to be manually modified on the sending end. waste

If the central terminal manages the file transfer tasks in a unified manner, the sending terminal cannot identify whether the task configuration is up-to-date, and needs to periodically synchronize task information from the central terminal, which will increase the load on the central terminal and also increase resource consumption. Updating task information is poor in timeliness, and there will be a problem that the task is not updated in time, which will lead to file transfer errors
