    Abstract: In a multi-source hybrid overlay network including a plurality of peers, an apparatus that recovers missing data occurring in a tree recovery process, acquires data that a peer does not have in a pull method through exchanging buffer maps with a first counterpart peer connected to a primary path recovered in the tree recovery process and at least one second counterpart peer connected to at least one candidate path, and provides data that the first counterpart peer does not have to the first counterpart peer in the push method, when a data recovery policy is a pull method, is provided.

    Abstract: A peer may receive a peer list from a hybrid overlay management server in response to an overlay network participation request of the peer, may select a first peer from the received peer list, may establish a connection with the selected first peer, and may establish a connection with at least one of second peers. Propagation of the overlay network participation request may be initiated by the selected first peer, and each of the second peers may correspond to a peer that receives the propagated overlay network participation request. One of the established connections may be determined as a primary path, and a communication may be performed through the primary path.

    Abstract: Hybrid overlay management server (HOMS) that manages a service of hybrid overlay network (HON) and a method of operating the HOMS are disclosed. The method includes: receiving a creation request for creating an HON and a service from a peer of a service owner; creating the HON and creating service information of the service; transmitting the service information to the peer of the service owner; receiving a join request for joining the HON and the service from a peer of a service user who intends to use the service; and verifying an access right of the service user, allowing the join request, and transmitting the service information to the peer of the service user, wherein the HON is a peer-to-peer overlay network over which joined peers exchange data, and the service is provided to the peer of the joined service user through the HON.

    Abstract: Disclosed is a display device connection method for rapidly delivering data to a plurality of display devices. A peer-to-peer (P2P) overlay network including the plurality of display devices as member peers is configured to distribute content. In this case, an overlay management server (OMS) connects first member peers through a network as a tree topology using a source peer providing the content as a root node, and transmits fragments of the content to a child peer based on a number of peers to which each of the member peers is capable of transmitting the fragments of the content for a preset period of time, and the source peer directly transmits the fragments of the content to a second member peer that is not included in the tree topology among the member peers based on a predetermined limit on a hop count.
