Abstract:With the increasing demand of application of streaming media, continuous improvement and perfecting the existing streaming media system performance is imperative, and introducing cloud computing into streaming media system becomes a major trend of the streaming media system. This paper simply analyzes the advantages and disadvantages of cloud computing, CDN and P2P networks, and research development. The paper mainly discusses the problems of P2P streaming media transmission system in the cloud environment which are bandwidth, process of streaming data, quality of service. After that, summarizing virtualization technologies, storage management techniques, scheduling techniques and replication technology in the system. Furthermore, from the perspective of building experimental environment of cloud computing, the paper cited some popular means of simulation.
