Glossary
Switch
Hardware that routes frames according to Fibre Channel protocol and is controlled by software.
Target
A storage device on a Fibre Channel network.
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).
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
Transmission Word
A group of four transmission characters.
Trap (SNMP)
The message sent by an SNMP agent to inform the SNMP management station of a critical error.
Tunneling
A technique for enabling two networks to communicate when the source and destination hosts are both on the same type of network, but are connected by a different type of network.
