Abstract

A user who uses a multimedia files demands a high capacity file via internet. However, it is difficult to guarantee QoS about providing high capacity files by internet because that has an inconstant bandwidth. For guaranteeing the QoS, CDN (Content Delivery Network) is generally used as a method of contents delivery service. Based on CDN, we propose Content Distribution and Management (CDM) using Metadata system which can provide advanced transmission and searching method. For enhancing a transmission rate, CDM system supports segment unit based transmission method that can be possible parallel transmission. Also, we propose a distribution method through substance based search. CDM system can primarily distribute the files which includes content that user wants. Information about substance of file is stored in metadata through contents metadata management interface, and then the information is inserted to the high capacity file itself. When user requests a high capacity file that user wants, CDM system doesn't transmit all of applicable contents but firstly transmits a particular part of applicable files. Also when contents distribute with substance search of CDM based on metadata, its transmission speed is 4.8 times faster than existing CDN. Therefore a proposed CDM system can guarantee QoS for user.
