Abstract (in Japanese) (See Japanese page) 
(in English) Ethernet has been applied to industrial in-vehicle, train and factory networks due to its high capacity and cost effectiveness. Since these networks are integrated to Ethernet, communication flows with different delay requirements will be multiplexed and transmitted. As a result, frames may collide with each other and delay requirements may not be satisfied. By applying Interspersing Express Traffic (IET), the delay induced by collision between a high-priority frame and a low-priority frame can be minimized, however the delay induced by collision between high-priority frames cannot. In this paper we formulated a constraint satisfaction problem (CSP), on the premise that IET will be applied, to compute paths that satisfy delay requirements of all communication flows, even if high-priority frames had the delay due to the collision. Furthermore, we evaluated the performance of existing search algorithms for the CSP by network simulation. As a result, min-conflicts heuristic has a 26% higher detection rate of a solution involving CSP at its maximum when compared to full search algorithms.
