Multi-task content updating method, device and equipment and medium

Abstract

The invention discloses a multi-task content updating method and device. The method comprises the following steps: enabling a node in a network to receive a plurality of updating tasks, and calling alocal updating task program to sequentially execute the updating tasks according to the descending order of the priority indexes of the updating tasks; and selecting a lower-level node according to the communication levels of the current node receiving the plurality of updating tasks and other nodes which do not execute the updating tasks, sending the plurality of received updating tasks to the lower-level node, and performing step-by-step analogy according to the method in sequence until all nodes in the network receive the plurality of updating tasks and execute updating. The method also hasthe advantage that the problem that the speed and the efficiency of file updating cannot be achieved at the same time on the basis of the traditional CDN technology is solved. The distributed cooperation ensures that all tasks can effectively and quickly reach all nodes, and ensures the integrity of the content. Distributed computing of content and scheduling is achieved, whole-network and whole-region access is achieved, the concurrence bottleneck is solved, and strong expansion of the whole system is achieved.

Description

[0001] This application is a divisional application of a Chinese patent application submitted to the Patent Office of the State Intellectual Property Office of China on March 1, 2017, with the application number 201710117463.X and the title of the invention "a method and device for updating content". technical field [0002] The invention relates to the field of network data transmission, in particular to a multi-task content updating method, device, equipment and medium. Background technique [0003] In the current network environment, contents such as pictures, webpages, music, videos, etc. usually use a content delivery network (Content Delivery Network, referred to as CDN) with caching nodes distributed all over the world to provide faster content access services for end users. Users can directly obtain specific cached content from the nearest content node without requesting content from the origin server. However, when the resources of the website are updated, all nodes...

AI Technical Summary

Problems solved by technology

[0005] 1. Once the network is out of order, judging from the current actual network situation, the traditional content update method may cause the server to be unable to obtain updates within the effective time of the task

At this time, the center will retransmit after receiving the tracking feedback, and the final efficiency will be greatly reduced;

[0006] 2. Content updates may involve a large number of Uniform Resource Locators (Uniform Resource Locators, URLs) at the same time. The message queue usually takes tens of thousands of milliseconds to process a URL, and a complete update of the entire network content takes several minutes or even tens of minutes. Minutes, obviously unable to meet the needs of enterprises;

[0007] 3. The message queue only queues up tasks based on the chronological order of task start, but the urgency of task update does not match the chronological order of task start, which leads to unfair task update
