Advanced Network Device Layer/
Software.
Hirschmann term for the
Device Driver level.
Aging.
When an entry for a node is
added to the lookup table of a
switch, it is given a timestamp. Each
time a packet is received from a
node, the timestamp is updated. The
switch has a user-configurable timer
that erases the entry after a certain
length of time with no activity from
that node.
Application Programming
Interface.
An API is an interface
used by an programmer to interface
with functions provided by an
application.
AVL tree.
Binary tree having the
property that for any node in the
tree, the difference in height
between the left and right subtrees
of that node is no more than 1.
B
BPDU.
Bootstrap Protocol.
An Internet
protocol that enables a diskless
workstation to discover its own IP
address, the IP address of a BootP
server on the network, and a file to
be loaded into memory to boot the
machine. This enables the
workstation to boot without requiring
a hard or floppy disk drive.
Bridge Protocol Data Unit.
BPDU
is the IEEE 802.1D MAC Bridge
Management protocol that is the
standard implementation of STP
(Spanning Tree Protocol). It uses the
STP algorithm to insure that physical
loops in the network topology do not
result in logical looping of network
traffic. Using one bridge configured
as root for reference, the BPDU
switches one of two bridges forming
a network loop into standby mode,
so that only one side of a potential
loop passes traffic. By examing
frequent 802.1d configuration
updates, a bridge in the standby
mode can switch automatically into
the forward mode if the other bridge
forming the loop fails.
C
Checksum.
A simple error-
detection scheme in which each
transmitted message is identified
with a numerical value based on the
number of set bits in the message.
The receiving station then applies a
formula to the message and checks
to make sure the accompanying
numerical value is the same. If not,
the receiver can assume that the
message has been corrupted.
Command Line Interface.
CLI is a
line-item interface for configuring
systems.
