Abstract :
Switched Ethernet combines Ethernet and ATM switching technology. The authors propose a probability based admission control algorithm over switched Ethernet to provide real time capability for control applications. The main contribution of the paper is providing an efficient means of estimating the queuing possibilities and the corresponding queuing delays inside the switch for periodic control system application. The approach enables switched Ethernet admission control without sophisticated packet scheduling in switches or middleware on hosts. The algorithm is analyzed and implemented to verify its feasibility
