摘要： The present invention relates to use of a circular buffer used by a peer in a multimedia streaming service based on peer-to-peer (P2P), and an operating method thereof. A circular buffer of the present invention may include a buffering section to process a delayed data fragment transmission request from at least one peer present in a network according to a playback of a multimedia content, a storing section to store data to be provided to the at least one peer, a continuous storing section in which data fragments for the playback of the multimedia content are stored in serial order, and a discontinuous storing section in which a space for a received data fragment to be shared with the at least one peer is reserved and a space for a data fragment to be received is reserved.
