Abstract

The invention discloses a method and system for downloading and updating a file. The method comprises the following steps: step one, a scheduling node receives file distribution information; step 2, the scheduling node sends an update task to a downloading node included in the file distribution information according to the file distribution information; step 3, the scheduling node receives a queryrequest for querying the downloading node with completely same or partially same updating tasks from the downloading nodes, and selects the downloading node with completely same or partially same updating tasks as this downloading node according to the file distribution information, and notifies the information of the selected downloading node to the downloading node. Through the method system disclosed by the invention, the bandwidth cost can be reduced, and the file distribution speed is accelerated.

Description

technical field [0001] The invention relates to the network field, in particular to a method and system for downloading update files. Background technique [0002] Content Delivery Network (CDN for short) is a layer of intelligent virtual network based on the existing Internet formed by placing download nodes throughout the network. Its purpose is to publish the content of the website to the "edge" of the network closest to the user by adding a new layer of network architecture to the existing Internet, so that users can obtain the required content nearby and improve the response speed of users visiting the website . The CDN network can redirect the user's request to the service node closest to the user in real time according to comprehensive information such as network traffic, connection of each node, load status, distance to the user, and response time. [0003] In a CDN network, when thousands or even tens of thousands of download nodes need configuration upgrades, sof...
