A FAIRNESS IMPROVEMENT METHOD OF ASSURED SERVICE WITHOUT PER FLOW MANAGEMENT IN DIFFSERV THROUGH NETWORKS WITHIN A VESSEL

摘要

PURPOSE: A fairness improving method is provided to improve link usage rates by improving fairness between TCP(Transmission Control Protocol) flows in a single domain and a multi-domain environment. CONSTITUTION: The yield fairness of an individual flow is improved in an integrated traffic management method in a differentiated service for a network in a ship. A TCP user uses AS(Assured Service) without managing user flows. The yield and the link usage rate are improved in a minimum bandwidth, a surplus bandwidth, and bandwidth shortage. The improvement of the yield fairness and the link use rate is confirmed in the improved single domain environment and the multi-domain environment.
