A METHOD FOR QOS GUARANTEE OF ASSURED SERVICE IN DIFFERENTIATED SERVICES THROUGH NETWORKS WITHIN A VESSEL

摘要

PURPOSE: A network service quality guarantee method in a ship is provided to set variables of RIO(RED(Random Early Detection) with In and Out) again by considering the maximum rate of the whole packets in fixed time sections. CONSTITUTION: A buffer size is determined by being allocated according to a network topology and an AS(Assured Service) sub-class. The variable values of the RIO are set by considering the whole packets and profile packets based on the determined buffer size in fixed time sections. When the profile packets and the whole packets are arrived, the number of the profile packets is determined in the fixed time sections according to the number of the whole packets.
