Autonomous Decentralized VoD Architecture to Achieve Service Assurance

摘要

In distributed and ubiquitous computing systems, they have been utilized under the evolving situation where the system structure itself, the composing subsystems, their functions, the accessible information would be changed constantly. With the advances of compression, storage and network technologies, Video on Demand (VoD) service is becoming more and more popular. However, it is difficult for conventional systems to meet the continuous and heterogeneous requirements from service providers and users simultaneously. This paper introduces an autonomous decentralized VoD system sustained by mobile agents for information service provision and utilization. Under the proposed architecture, autonomous coordination technology for node adjustment is proposed to achieve load balance and continuous service in the situation of changing users preference. The effectiveness of the proposed technology is proved by the simulation.
