DATA PACKET TRANSMISSION AND RECEPTION METHOD IN A RING NETWORK AND RING NETWORK NODE TERMINAL CAPABLE OF TRANSMITTING A DATA PACKET WITHOUT LOSS

摘要

PURPOSE: A data packet transmission and reception method in a ring network and ring network node terminal are provided to construct a reliable power network by transmitting data according to the order of priority.;CONSTITUTION: A packet processing module receives a data packet from a signal processing module(S410). The packet processing module determines the data packet as two-way data(S420). The packet processing module inserts a tag bit for separating a left ring from a right ring into the data packet and the copied data packet(S430). The packet processing module transmits the data packet to a packet transmission and reception processing unit(S440).;COPYRIGHT KIPO 2012
