Abstract


Due to the rapid development of the computer network , the surge in the amount of data that makes computer storage technology to the development of the depth direction . Traditional content distribution network has gradually transformed into a mode of content distribution network combined with P2P technology . P2P divided in terms of the the hairnet system 's performance , we have two important measure conditions : reliability and availability . Reliability refers to permanent data loss in the system . Availability refers demand , want to get the data acquisition speed but also user satisfaction with the job . This subject attempts in the process of transferring data using a network coding technology , and it is introduced into the P2P content stars Home System replica management process , in order to solve the node status is changed frequently , and the redundant data maintenance system reliability problem , making the system more qualified for the state of open networks , P2P content distribution network , and the content of the thesis work are as follows : ( 1 ) in the copy of the distribution network management through a comprehensive analysis of the contents of some of the defects , take the introduction of network coding strategy , the theoretical basis and work before the fully prepared. (2 ) to the ideas into points in the existing content Home system is designed and implemented on top of the the replica management module and codec module . ( 3 ) Design a simple experiment simulation , create a copy of the front and rear of network coding , the copy of the file recovery node regeneration success rate compared to charts than on transmission time before and after the two programs . Finally, the simulation tests , the experimental results with the expected agreement . Replica management program using network coding technology , reliability and system speed of response , and many other , has a very good performance , can effectively reduce the copy of the file transfer time , but also significantly reduce the rate of data transmission bandwidth usage .
