Video distributed storage and centralized management system

The invention discloses a video distributed storage and centralized management system. The system comprises a distributed storage and centralized management architecture, the invention discloses an IPSAN (Internet Protocol Storage Area Network) network architecture based on an iSCSI (Internet Small Computer System Interface) technology. And the streaming media server is used as core equipment forstoring the solution. The invention further discloses an access control strategy based on dynamic threshold optimization and an implementation method, and the safety of information collection is guaranteed. According to the invention, the multi-node video storage management architecture is optimized, and the storage is relatively centralized and easy to maintain; and the storage is more specialized, the storage reliability is improved, and the storage expansibility becomes better. 本发明公开了一种视频分布式存储与集中管理系统，包括：分布式存储，集中管理架构；基于iSCSI技术的IPSAN(STorageAreaNetwork)网络架构；流媒体服务器作为存储解决方案的核心设备。本发明还公开了一种基于动态阈值优化的访问控制策略和实现方法，保证了获取信息的安全
