Problems solved by technology

[0004] It is not difficult to know that when the disk storage space of the node is small, the streaming media files that can be stored in the node will be less, so the probability of returning to the source to respond to user requests will be correspondingly greater. In an ideal state, It is hoped that the disk storage space of the node is large enough to store all streaming media files to reduce the chance of returning to the source to zero. However, large network service operators operate tens of millions of

Abstract

The invention provides a node disk space determining method. The method comprises the steps of obtaining the multi-group cache hit ratio under multiple disk spaces, the disk response duration and the loop-source duration; on the basis of the determined multi-group cache hit ratio, the disk response duration and the loop-source duration, determining multiple expected response durations; according to a ratio of the determined multiple disk response durations to the corresponding expected response durations, determining various access execution efficiencies; determining a disk space corresponding to the access execution efficiency, within the preset target access execution efficiency range, of the multiple access execution efficiencies as a node disk space. The invention further provides a node cache optimization system. A web service operator can visually balance the relation between the user experience and the node disk space, and cannot waste the node disk space on the premise of ensuring the node user experience.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of content distribution networks, and in particular, to a node cache optimization method and system. Background technique [0002] CDN (Content Delivery Network, Content Distribution Network) is a layer of intelligent virtual network based on the existing Internet formed by placing node servers throughout the network. CDN can redirect the user's request to the service node closest to the user based on comprehensive information such as network traffic, connection of each node, load status, distance to the user, and response time in real time. The nodes send the content required by the user to the user, relieve the network congestion, and improve the response speed of the website. [0003] Currently, in a CDN network serving streaming media services, when a user accesses a certain streaming media file, after the CDN scheduling process, the user access is scheduled to the node closest to...
