Storage service middleware based on mobile caching

Abstract

Wide area networks (WAN) storing service intermediate parts based on the mobile caching technique, pertains to data accessing management intermediate parts in the computer network memory technique field, which resolve problems of slow data transmission and bad safety of IPv6 WAN distributed storage system. The present invention includes data transmission, mobile caching and security modules, wherein, the data transmission module includes metadata management, service request, and service processing sub-modules, as well as request monitoring and request handling sub-modules; the mobile caching module includes a mobile caching selection sub-module and a mobile caching transmission sub-module; the security module includes a tripartite safety authentication sub-module and a authority detection sub-module. The invention realizes a compact and quick response from customer nodes to storage systems; makes full use of high performance and high-speed network band-width between storing service nodes; during data transmission, dynamically selects optimal storing service nodes for data as mobile caching; has a comprehensive and practical storage service function, and fast and secure data transmission performance; and ensures high-speed and security of network data moving.

Description

technical field [0001] The invention belongs to the data access management middleware in the technical field of computer network storage, and is based on the mobile cache technology in the wide area network environment. Background technique [0002] Multimedia and network applications have led to explosive growth of digital information, and the demand for storage in terms of both quality and quantity is also increasing. At the same time, due to the constraints of the data transmission rate of the network and storage interfaces, data transmission is slow and channel efficiency is not high. , The access speed is slow, and the waiting time for responding to user requests is long; the security, integrity, and quality of service of the transmitted data cannot be guaranteed. Especially in the wide area network environment, due to the huge differences in geographical location and network environment between the client node and the storage service node, the problem of data transmiss...
