Source: Korea University
Recently, user who uses a multimedia files demand 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, the authors propose Content Distribution and Management using Metadata (CDM) 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, they propose a distribution method through substance based search. CDM system can primarily distribute the files which include content that user wants.
