SNMP
Simple Network Management Protocol. An internet management protocol that
uses either IP for network-level functions and UDP for transport-level functions,
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.
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 well-known address.
May also be referred to as directory service.
switch
Hardware that routes frames according to fibre channel protocol and is controlled
by software.
switch port
A port on a switch. Switch ports can be E_Ports, F_Ports, or FL_Ports.
SWL
Short wavelength. A type of fiber optic cabling that is based on 850mm lasers and
supports link speeds up to 2 Gbit/sec. May also refer to the type of transceiver.
T
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.
transmission character
A 10-bit character encoded according to the rules of the 8b/10b algorithm.
