Abstract: A method of forming a federated digital twin and a digital twin for performing the method are disclosed. The digital twin includes general functions (GF) configured to provide a function and data of the digital twin and federation orchestration functions (FOF), wherein the FOF are configured to discover one or more other digital twins to federate with the digital twin, determine, from among the discovered digital twins, a digital twin to form a federated digital twin, and form the federated digital twin by establishing a communication connection with the determined digital twin.

Abstract: Disclosed are a method and apparatus for transmitting artificial intelligence-based data by using a distributed network. An operating method of a first agent includes transmitting a key frame of an input video received from a first client corresponding to the first agent to a second agent and receiving, from the first client, key points extracted from the input video as features for every frame after the key frame and transmitting the received key points to the second agent. The first agent and the second agent communicate through a distributed network.

Abstract: A resource allocation method of an overlay management server (OMS) is disclosed. The resource allocation method may include transmitting, to a cache server (CS), a remote peer list determined based on a network distance between each of peers and the CS, receiving, from the CS, a peer list including an identifier of a peer receiving contents from the CS in response to the identifier of the peer being included in the remote peer list, and selecting another CS for the peer in response to the peer list being received.

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.

Abstract: Disclosed is a method of adjusting a starting point of a peer, the method including receiving a starting point value and a downloading point value of a counterpart peer from the counterpart peer, determining an initial starting point value of a peer based on the received starting point value and the received downloading point value, calculating a ratio between an average play point move rate (APMR) of the peer and an average fragment reception rate of the peer when the determined initial starting point value is less than the received starting point value, calculating a margin based on the calculated ratio, and determining the starting point value of the peer using one of the received starting point value and the received downloading point value, and the calculated margin.
