This paper presents a new approach to design a realtime Industrial-Ethernet network with the feature to add asynchronous sending devices like laptops or personal computers to the network without affecting the realtime performance. The idea is based on the modification of switching engines with usage of standard cabling and network interface cards. Although the implementation is similar to Siemens...
This paper presents a top-down approach to design switched Ethernet networks based upon tree topologies for realtime automation systems. The approach considers each port of a switch as an exclusive networking resource and thus permits concurrent communication over different ports. We firstly focus on a class of special cases with unitary packet-sizes and transmission of each request in every production...
