METHOD, DEVICE AND SYSTEM FOR REAL-TIME PUBLISH SUBSCRIBE DISCOVERY BASED ON DISTRIBUTED HASH TABLE

摘要

PURPOSE: A distributed hash table based RTPS(Real-Time Publish Subscribe) discovery method, apparatus, and system thereof are provided to operate an SPDP(Simple Participant Discovery Protocol) through unicast by acquiring the location information of an RTPS(Real-Time Publish Subscribe) participant peer through the DHT(Distributed Hash Table) of an overlay network. CONSTITUTION: A participant peer(124) of a participant(134) registers the participant in a DHT of an overlay network. The participant peer acquires the location information of the opponent participant from the DHT. The participant peer exchanges discovery messages with the peer of the participant. Objects of the participant execute handshaking with the object of the opponent participant.
