Abstract (in Japanese) (See Japanese page) 
(in English) Ethernet is prevailing in industrial networks due to its high capacity and cost effectiveness. In such networks, a large number of traffic with different priorities are multiplexed into one network. By applying time division multiplexing control method for Scheduled-traffic specified in IEEE 802.1Q-2018 that is one of the TSN (Time Sensitive Networking) standard, it is possible to schedule plural traffic for each class and guarantee real-time property of traffic. To date, a method for calculating appropriate scheduling parameters have been proposed, but it has a problem that a solution can not be calculated when collision from different nodes occurs on the communication path. In this research, we developed software that calculates appropriate scheduling parameters even when collision occurs. As a result, we have found that proposed method could calculate the parameters even when collision occurs, and calculate it for networks with maximum link utilization of 48%, while the existing method can calculate it for networks with one of 45%.
