CONTENTS SERVING SYSTEM AND METHOD TO PREVENT INAPPROPRIATE CONTENTS PURGING AND METHOD FOR MANAGING CONTENTS OF THE SAME

摘要

A content providing system and method for preventing improper content deletion, and a content managing method thereof are provided to fundamentally prevent a content service provided or to be provided to a client from being interrupted by improper deletion of a content file, as sync information of the contents is updated by a request or a result of the content service. A content storing part stores available content information. A sync information storing part stores the sync information of the available content information. Each server node(120a-120d) provides the content service after changing the sync information of the contents corresponding to a received content service request. A dispatcher node(110) selects the server node for providing the content service after checking a service state of the requested contents from the sync information storing part, and transmits address information of the selected server node and content file information to the client after changing the sync information of the requested contents. A storage/deletion management mode(130) manages storage/deletion of the contents stored in the content storing part by referring to the sync information.
