Method and system for distributing cross-region efficient storage content

Abstract

The invention provides a method and a system for distributing cross-region efficient storage content, which achieve an overall unified name space, also achieve that a user can visit and operate the content in whole system at any client, and thereby reduce management and operating difficulty. According to the method and the system for distributing cross-region efficient storage contents, a plurality of content distribution strategies are supported, the active push and passive fetch of the content can be achieved, and the content distribution efficiency is improved; a plurality of data protection strategies are supported, and the customized protection strength of the file is supported; the data scheduling of the whole system is supported, and the flow of the wide area network is reduced.

Description

technical field [0001] The invention relates to a network data processing technology, in particular to a method and system for distributing cross-regional and efficient storage content. Background technique [0002] With the popularization of cloud computing technology, the amount of data generated by enterprises is increasing, which has reached the PB level, and the data volume of tens of millions of objects requires a storage system that can support efficient access to massive data; because enterprise data is generally deployed in multiple different sites, in order to achieve unified management, the management and access of cross-regional data requires the support of the storage system. [0003] The existing traditional CDN (Content Distribution Network) system deploys CDN nodes in multiple locations, and each CDN node provides content caching, content management, load balancing, and traffic management functions. The CDN system distributes the content to the nearest CDN n...

AI Technical Summary

Problems solved by technology

[0007] 1. In the existing systems, such as the CDN system realizes the distribution of content, but does not pay attention to the operation and management of the content; although other file systems supporting the wide area network realize the aggregation of cross-site data, the global namespace is not a unified Namespace, the user still needs to specify the access location

[0008] 2. As far as global data scheduling is concerned: the CDN system only distributes content and load balances according to the user's access behavior, and does not know the global behavior

The CDN system achieves partial fault tolerance by distributing content to CDN nodes in different regions, but does not realize system-wide data protection

[0010] 4. Difficulty in system development: CDN system content management and content modification need to be implemented outside the CDN system; private cloud storage systems generally provide private APIs for programming and use, which are difficult to develop and use
