Glossary
Interface (1) A shared boundary between two functional units, defined by
functional characteristics, signal characteristics, or other
characteristics as appropriate. The concept includes the specification
of the connection of two devices having different functions. (2)
Hardware, software, or both, that links systems, programs, or
devices.
Internet Protocol See IP.
Interoperability
The ability to communicate, execute programs, or transfer data
between various functional units over a network.
Interswitch Link See ISL.
IP
Internet Protocol, the TCP/IP standard protocol that defines the
datagram as the unit of information passed across an internet and
provides the basis for connectionless, best-effort packet delivery
service. IP includes the ICMP control and error message protocol as
an integral part.
IP Address A unique string of numbers that identifies a device on a network. The
address consists of four groups (quadrants) of numbers delimited by
periods. (This is called dotted-decimal notation.) All resources on the
network must have an IP address. A valid IP address is in the form
nnn.nnn.nnn.nnn, where each nnn is a decimal in the range 0 to 255.
IPL Initial Program Load, initiated through a menu option in a
Connectrix switch Product Manager. This performs the same function
as an IML, but resets the active CTP only. It does not affect the backup
CTP subsystem if it is installed.
ISL A physical E_Port connection between two switches in a fabric.
L
Laser A device that produces optical radiation using a population inversion
to provide light amplification by stimulated emission of radiation
and (generally) an optical resonant cavity to provide positive
feedback. Laser radiation can be highly coherent temporally, spatially,
or both.
LED Light-emitting diode.
Link
The physical connection between two devices on a switched fabric.
