Patent ID: 7873609

Claim:
A contents distribution management system with a multi-service type management function, the system comprising: a plurality of global servers for supplying contents to a plurality of local servers, each global server having a large capacity contents library; and the local servers for managing the contents provided from the global servers based on global servers and service types using contents tables, and providing a contents service in response to a contents streaming service demand from a last terminal using a local contents cache, wherein when the service demand is the addition of a service, adding one row or one directory to each of a contents storage policy table, a local contents cache and a storage management table; wherein when the service demand is the elimination of a service, eliminating a corresponding one row or one directory from each of the contents storage policy table, the local contents cache and the storage management table; wherein when the service demand is a change of the service, changing field values of a corresponding row in each of the contents storage policy table, and the storage management table; wherein contents of the global servers demanded from the last terminal being managed using predetermined rules to provide an available storage space in the local content cache for the demanded contents, the demanded contents having a required storage space and a service type, the predetermined rules comprising: eliminating, when the available storage space is less than the required storage space, contents from the local contents cache are eliminated in accordance to a purging priority policy based on both the service type and a priority ranking wherein the purging priority uses a least recently used algorithm to select contents in the local contents cache that are not used for a longest period of time, a usage frequency algorithm that selects least served contents in the local contents cache, and an age algorithm that selects contents in the local contents cache installed before a longest time; choosing contents to be transmitted from the global servers in advance of the local servers by using a rank policy and a newage policy wherein the rank policy selects contents as a function of a highest usage frequency of the global servers and as a function of different profit structures of the global servers wherein the newage policy selects contents most recently installed in the system; and subsequently updating the available storage space in the local content cache.
