N_Port (Node Port)
CONTEXT [Fibre Channel] A “Node” port connects via a point-to-point link to either a single N_Port or a single F_Port. N_Ports
handle creation, detection, and flow of message units to and from the connected systems. N_Ports are end ports in virtual
point-to-point links through a fabric, for example, N_Port to F_Port to F_Port to N_Port using a single Fibre Channel fabric
switch. (The Dictionary of Storage Networking Terminology)
