Content distribution network (CDN) node based cache centralized management system

Abstract

The invention discloses a content distribution network (CDN) node based cache centralized management system. The system is characterized by comprising one or a plurality of following modules: a network element management module, a topological management module, a performance management module, a fault management module, a statement management module and a system management module. The system adopts a centering-edge layered architecture. One or a plurality of demanded functional modules are extracted from a centralized layer and an edge layer so as to form an independent management system and are deployed on all cache nodes so as to control and manage a single cache node. Through adoption of the layered architecture in the CDN node based cache centralized management system, the management manner of centering-edge regional autonomy can be realized according to network conditions of different regions and use habits of the user, so that devices at the edge layer are managed by self, furthermore, the network data transmission traffic is reduced, and the transmission efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of content distribution network, in particular to a CDN node-based centralized cache management system. Background technique [0002] With the gradual maturity of the Internet business layout and the gradual enrichment of network access modes, the network scale has grown rapidly. However, the basic network construction has not been able to keep up with the growth of network business needs. In order to enable users to access relevant content in the network in a timely and fast manner, CDN technology has emerged as the times require. [0003] The full name of CDN is ContentDistribution / DeliveryNetwork, that is, content distribution network. Its principle is to publish the content of the website to the cache node closest to the user by adding a new layer of network architecture to the existing Internet, so that the user can get all the content nearby. The required content, reduce the delay, and solve t...

Problems solved by technology

[0004] However, with the continuous increase of cache nodes, the current content distribution network has insufficient ability to collect performance data and business data of each node, which not only makes the huge amount of data transmitted, but also causes the lag of data display, and cannot realize efficient caching centralized control

At the same time, the upgrade and system configuration of the current cache nodes require staff to go to each computer room for on-site operations, which is not only inefficient, but also wastes manpower and material resources
