Abstract
Disclosed herein is a method and system for providing a Peer-to-Peer (P2P) live streaming service over a Content Distribution Network (CDN). The method includes the steps of (A) a peer present on a network searching for an adjacent surrogate, that is, a superpeer in a bin where peers are grouped, (B) the peer sending a content request message to the surrogate, (C) the surrogate finding a corresponding peer list and then sending the peer list to the peer in response to the content request message, or, if the surrogate cannot find a peer list corresponding to the content request message and makes a request to a surrogate overlay, the surrogate overlay sending information about a surrogate having corresponding content to the peer, and (D) the peer requesting content from the surrogate having sent the peer list or from a surrogate included in the information about a surrogate, and receiving the corresponding content.
