IBM AA-RWF3A-TE manual public loop, arbitrated loop

public loop	An arbitrated loop that includes a participating FL_Port and
	may contain both public and private NL_Ports. See also
	arbitrated loop.
public NL_Port	An NL_Port that logs in to the fabric, can function within a
	public or private loop, and can communicate with private or
	public NL_Ports. See also private loop.
quad	A group of four adjacent ports that share a common pool of
	frame buffers.
R_A_TOV	Resource allocation time-out value. The maximum time a frame
	can be delayed in the fabric and still be delivered.
route	With respect to a fabric, the communication path between two
	switches. May also apply to the specific path taken by an
	individual frame from source to destination.
routing	The assignment of frames to specific switch ports according to
	frame destination.
RR_TOV	Resource recovery time-out value. The minimum time a target
	device in a loop waits after a LIP before logging out a SCSI
	initiator.
RSCN	Registered state change notification. A switch function that
	allows notification of fabric changes to be sent from the switch
	to the specified nodes.
SAN	Storage area network. A network of systems and storage
	devices that communicate using FC protocols.
SDRAM	Synchronous dynamic random access memory. The main
	memory for a switch. See also switch.
sequence	A group of related frames transmitted in the same direction
	between two N_ports.
single mode	The fiber optic cabling standard that corresponds to distances
	up to 10 km between devices.
SNMP	Simple Network Management Protocol. An Internet
	management protocol that uses either IP for network-level
	functions and UDP for transport functions, or TCP/IP for
	both. SNMP can be made available over other protocols
	(such as UDP/IP) because it does not rely on the underlying
	communication protocols. See also MIB, trap (SNMP).
SNS	Simple Name Server. A switch service that stores names,
	addresses, and attributes for up to 15 minutes, and provides
