Problems solved by technology

[0005] However, the above-mentioned technical solution has the following disadvantages: the solution only meets the quality of service requirements by controlling and adjusting the CDN network path for user access and the selection of Cache server nodes, and this is only a part of the factors that affect the quality of service in the CDN. For content resources Factors such as pre-distribution of Cache server nodes and caching control of Cache server nodes are not controlled, so they cannot well meet the requirements of quality of service control

Embodiment Construction

[0057] The QoS control system in the content distribution network of this embodiment includes: a service management system, a CDN management system, at least one source server node, and multiple Cache server nodes.

[0058] Among them, the functions of the service management system mainly include: storing service levels of different contents; controlling CDN global service parameters; distributing service control parameters to Cache server nodes, so as to provide different quality services for different levels of services.

[0059] The CDN management system is mainly responsible for managing Cache server nodes, pre-distributing content to Cache server nodes, and guiding user requests to Cache server nodes in a balanced manner.

[0060] Cache server nodes store content entities at the edge of the network. It is also responsible for receiving the service control parameters sent by the service management system, and providing different quality services for different contents acco...

Abstract

The invention discloses a method and a system for service quality control in a service delivery network. A CDN management system provides different numbers of copies and different placement positions for contents of different service grades according to service grade information of various contents maintained by a service management system when pre-distributing content copies. According to the invention, the service management system controls copy pre-distribution of the CDN management system to enable contents of different service grades to obtain copy placement qualities of different grades, thereby saving storage resources of Cache server nodes on the whole and ensuring that better services can be provided for higher-grade contents. In addition, cache and service of the Cache server nodes can be controlled by the service management system so that contents of different service grades can obtain cache qualities and service qualities of different grades, thereby ensuring high-quality service for a specific content.

Description

technical field [0001] The present invention relates to the technical fields of computer software and computer network, and more specifically, to a method and system for controlling service quality in a service distribution network. Background technique [0002] The Content Delivery Network (CDN for short) is an overlay network on top of the IP layer network, which is used to increase the speed of users' access to Internet content. Before adopting CDN technology, content consumption users directly access the content source server to obtain the content published by the content publisher. In the case of a large number of access requests, the content source server is under greater pressure. To this end, the CDN caches the content from the content source to the CDN cache (Cache) server at the edge of the network, and the content consumer obtains the content from the closer cache server. In this way, the pressure on the content source server can be relieved, the traffic of the ...
