service-level agreement
An SLA is a service contract between a network service provider and a
customer that guarantees a particular QoS. SLAs are used for providing
network availability and data-delivery reliability.
simple network management protocol
A protocol used for the transport of network management information
between a network manager and a network element. SNMP is the most
commonly used standard for interworking devices.
An SNMP trap is an unsolicited notification that indicates that the SNMP
agent on the node has detected a node event, and that the network
management domain should be aware of the event. SNMP trap information
typically includes alarm and status information, and standard SNMP
messages.
The name for the UNIX operating system variant developed by SUN
Microsystems.
synchronous optical network
SONET is an ANSI standard for fiber optic transmission of high-speed
digital traffic. SONET allows internetworking of transmission products
from multiple vendors and defines a physical interface, optical line rates
known as OC signals, frame format, and an OAM protocol. The base rate is
51.84 Mb/s (OC-1), and higher rates are multiples of the base rate.
SONET uses synchronous high-speed signals and provides easy access to
low-speed signals by mapping them into VTs.
SONET is a North American standard that is technically consistent with
SDH, which is international.
A technique used to gain unauthorized access to devices, whereby the
intruder sends messages to a device with an IP address indicating that the
message is coming from a trusted host.
secure shell
The SSH protocol is used to protect communications between two hosts by
encrypting a Telnet or FTP connection between the 5620 SAM and some
nodes. 5620 SAM uses SSH version 1.5. Both ends of the client/server
connection are authenticated, and passwords are protected by being
encrypted.
technical assistance center
The front end, or customer-facing product support structure in which the
first- and second-level support reside.
