SISequence Initiative.
Single Mode The fiber optic cabling standard that corresponds to distances of up to 10 km
| between devices. |
SNMP | Simple Network Management Protocol. An internet management protocol that |
| uses either IP for |
| or TCP/IP for both. Can be made available over other protocols, such as UDP/IP, |
| because it does not rely on the underlying communication protocols. See also |
| Community (SNMP). |
SNS | Simple Name Server; a switch service that stores names, addresses, and attributes |
| for up to 15 minutes, and provides them as required to other devices in the fabric. |
| SNS is defined by Fibre Channel standards and exists at a |
| May also be referred to as directory service. See also FS. |
Switch
Switch Name Switch Port
SWL
Hardware that routes frames according to Fibre Channel protocol and is controlled by software.
The arbitrary name assigned to a switch.
A port on a switch. Switch ports can be E_Ports, F_Ports, or FL_Ports.
Short Wavelength; a type of fiber optic cabling that is based on 850mm 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.
Translative | A mode in which private devices can communicate with public devices across the |
Mode | fabric. |
Transmission | A |
Character |
|
Transmission | A group of four transmission characters. |
Word |
|
Trap (SNMP) | The message sent by an SNMP agent to inform the SNMP management station of |
| a critical error. See also SNMP. |
Trunking Tunneling
See ISL Trunking.
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.
