¿µ¹®³»¿ë¿ä¾à In many LAN-connected WAN environments, it is necessary to reduce the amount of data transmitted because the latency transmitted over the network is relatively longer than in the LAN environment, and the communication cost may increase depending on the size and amount of data. In this standard, we propose a method to change the header structure of RTPS messages to improve the transmission efficiency of messages in the WAN environmemts, and to compress and transmit sub-message using flag fields within sub-message
