Abstract :
In this paper, the theoretical studies and solutions regarding problems for realizing Soft TCCS (Time Critical Communication System), residing on top of Ethernet LAN are presented. We analyze Ethernet LAN including its precise back off sequence to obtain throughput and delay characteristics in a light loaded circumstances. We also analyze the same performance characteristics effected by multi-modal condition which is the mode of transmitting both short packets for control messages and long packets for bulk data concurrently in Factory Automation system. These theoretical studies are validated through computer simulations. We end by presenting the definition of the bandwidth in Ethernet LAN and also formulae regarding its estimation needed for admission control to maintain the total load within the predetermined value
