CIRCULAR BUFFER AND METHOD FOR MULTIMEDIA STREAMING SERVICE BASED PEER-TO-PEER

摘要

PURPOSE: A circular buffer and an operation method for a peer-to-peer based multimedia streaming service are provided to reduce the size of data segment retention information exchanged in a peer-to-peer network by using a minimum memory or a local disk space. CONSTITUTION: A buffer section(200) processes a delayed data segment request which is transmitted from one or more peers existing in a network depending on multimedia content production. A storage section(201) stores data provided to the peers. Data segments for the multimedia content production exist in a raw in a continuous retention section(202). A space for the received data segments in order to share the data segments with the peers and a space for non-received data segments are mixed in a discontinuous retention section(203).
