topology With respect to FC, the configuration of the FC network and the resulting communication paths
allowed. There are three possible topologies:
• Point-to-point: A direct link between two communication ports
• Switched fabric: Multiple N_Ports linked to a switch by F_Ports
• Arbitrated loop: Multiple NL_Ports connected in a loop
