Glossary
Switch Name
The arbitrary name assigned to a switch.
Switch Port
A port on a switch. Switch ports can be E_Ports, F_Ports, or FL_Ports.
Switch
Hardware that routes frames according to Fibre Channel protocol and is controlled by
software.
SWL
Short Wavelength; a type of fiber optic cabling that is based on 850-mm lasers and supports
1.0625-Gbps link speeds. May also refer to the type of GBIC or SFP. See also LWL.
Target
A storage device on a Fibre Channel network. See also Initiator.
Tenancy
The time from when a port wins arbitration in a loop until the same port returns to the
monitoring state. Also referred to as loop tenancy.
Throughput
The rate of data flow achieved within a cable, link, or system. Usually measured in bps (bits
per second). See also Bandwidth.
Topology
As applies to Fibre Channel, the configuration of the Fibre Channel 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.
Transfer State
The state in which a port can establish circuits with multiple ports without reentering the
arbitration cycle for each circuit. This state can only be accessed by an L_Port in the Open
state.
Translative Mode
A mode in which private devices can communicate with public devices across the fabric.
Transmission Character
A 10-bit character encoded according to the rules of the 8B/10B algorithm.
Transmission Word
A group of four transmission characters.
