METHOD AND APPARATUS FOR DECIDING PARTICIPANT DISCOVERY MESSAGE PERIOD IN DDS MIDDLEWARE COMMUNICATION

摘要

Disclosed herein are a method and an apparatus for determining a participant discovery message period, which can adjust the period of domain participant discovery messages in consideration of variability in network and the importance of participants. An apparatus according to the present invention includes a network stability ratio calculation unit for calculating a network stability ratio based on a domain leave rate of participants; an ANPP (Adapted_Network_PDP_Period) calculation unit for calculating a participant discovery message period depending on a variation in network status based on the network stability ratio; a priority analysis unit for analyzing preset priorities of participants; and a participant discovery message period determination unit for determining a final participant discovery message period based on both the participant discovery message period depending on the variation in network status and the participant priorities.
