Description

In the multimedia applications, service and devices, multimedia delivery is expected to become the major traffic of Internet which will keep increasing rapidly. Along with the growth of users and the amount of media content constantly being produced, traditional cloud-based storage has two drawbacks. To proposes a robust, scalable, highly available and service level provisioning cloud-based storage system designed specifically for distributing multimedia content. A lot of servers and storages devices are needed, which could easily be the performance bottleneck in the whole system. To provide differential classes of services in the large-scale situation, system tends to need many additional devices. This article proposes a robust, scalable, highly available and service level provisioning cloud-based storage system designed specifically for distributing multimedia content. To provide differential service levels. The system can also be used flexibly in large, medium and small-scale environment. In addition, some algorithms are also developed to increase overall system performance and fault tolerance.
