- Abstract
- This paper presents a new approach to add asynchronous sending devices like Laptops or Personal Computers to the RAPIEnet (Real-time Automation Protocol for Industrial Ethernet) network without affecting the real-time performance. As a research result in formal modeling, we present a way to generate bipartite conflict graphs out of a given network infrastructure and communication requests of the devices. This graph can be colored in polynomial time, which leads to obtain schedules for each switch to be uploaded offline. Then we will be able to identify empty time slots which can be used to forward nRT traffic of asynchronous devices. ©2009 IEEE.
