VIRTUALIZED NODE, USER NODE EMPLOYING VIRTUALIZED NODE, AND CONTENTS SHARING METHOD USING VIRTUALIZED NODE

摘要

PURPOSE: A virtualization node, a user node for sharing content by installing the virtualization node, and a content sharing method using the virtualization node are provided to share the content among swarms through a user lead type of a virtualization node which is generated through virtualization, thereby allowing a user node to efficiently secure the content. CONSTITUTION: A sharing unit(110) downloads and stores a chunk which comprises content by participating in a swarm which shares the same content among peer nodes. The sharing unit shares the chunk in the swarm. A virtualization node installation unit(130) determines necessity of a virtualization node and installs a download virtualization node which is operated as a peer node of another swarm. A virtualization node control unit(150) controls the download virtualization node so that the download virtualization node downloads a part of chunk in another swarm. A virtualization node connection unit(170) receives the chunk.
