The Storage Technology Research Of Broadcasting And TV Vedio Contents Based On Triple-play Service

With the rapid development of information technology and the increasing promotionof triple play, the relatively closed telecommunications network and broadcasting networkhave been accessed to the internet,which directly leads to the explosive growth of theInternet data and user scales. After the convergence of the triple play, the openness andinteraction of the networks have been constantly upgrading, and other converged servicessuch as online video, audio have gained potential development, which on one hand greatlyenriches the spiritual life of the major consumers, and on the other hand poses seriouslychallenges to the security of triple play.The HUSTRIM system,based on the supervision of triple play by independentdeveloping has the characteristics of high-performance of data processing,highrequirement of broadhand,huge storage capacity and strong real-timeliness in accordancewith the video content of triple play. We also explore a kind of storage structure whichmeets the requirement of video supervising,functional storage and performancerequirement by in-depth analysis of massive amounts of data storage architectures.The HUSTRIM storage subsystem realizes the massive and unstructured data storageof triple play,which provides the other subsystems with efficient storage and searchsupport.First of all,the HUSTRIM analyzes the reliability,extensibility,fault tolarance,andconstruction cost.Then,it discusses about the technology of massive data storage andprinciples and what they really demand to the specific functionality and performance ofthe storage system.Meanwhile,it researches the HDFS storage structure which is based onGoogle cloud storage.In the end,we have developed one type of storage structure withhigh availability,concurrency and scalability according to the study above to meet thefunctional and efficiency requirment of the HUSTRIM storage subsystem.
