Jitter
Jitter is the variation on packets arriving on a SmartNode.
See also dejitter buffer.
Mode
The SmartWare CLI is comprised of modes. There are two
basic mode groups, the execution mode group and the
configuration mode group. See Chapter 5, “Command Line
Interface” for more details.
Network Management System
System responsible for managing at least part of a network.
An NMS is generally a reasonably powerful and well-
equipped computer, such as an engineering workstation.
NMSs communicate with agents to help keep track of
network statistics and resources.
Node
Endpoint of a network connection or a junction common to
two or more lines in a network. A Node can be a router, e.g.
a SmartNode. Nodes, which vary in routing and other
functional capabilities, can be interconnected. Node
sometimes is used generically to refer to any entity that can
access a network, and frequently is used interchangeably
with device.
Nodename
Name given to a SmartNode or network element.
nvram:
Persistent memory section of a SmartNode containing the
startup configuration, the factory configuration and used
defined configurations.
Operator
The person who has limited access to the SmartWare CLI.
PCI Local Bus
The PCI Local Bus is a high performance, 32-bit or 64-bit bus
with multiplexed address and data lines. The bus is intended
for use as an interconnect mechanism between highly
integrated peripheral controller components, peripheral add-
in boards, and processor/memory systems.
PCM Highway
A 30 channel interface connecting the switching engine with
optional interface cards containg circuit ports.
PMC
The optional interface cards for SmartNode 2000 series
which are compatible to the PCI Mezzanine Card standards.
PMC Driver Software
PMC driver software performs the runtime tasks on the PMC
interface card mounted in SmartNode 2000 series devices.
The PMC drivers are interface card specific and also have
build numbers. Refer to the SmartWare release notes for
PMC driver software compatibility. The PMC drivers may be
upgraded together with the SmartWare release or they can
be downloaded individually into the persistent memory
(flash:) of a SmartNode.
PMC Loader
The PMC loader initialises the PMC interface card mounted
in SmartNode 2000 series of devices. It checks hardware
versions and determines if compatible PMC drivers are
available. The PMC loader may be upgraded together with
the SmartWare release.
