CSMA/CD Carrier Sense Multiple Access with Collision Detection.
Media-access mechanisms wherein devices ready to transmit data
first check the channel for a carrier. If no carrier is sensed for a
specific period of time, a device can transmit. If two devices transmit
at once, a collision occurs and is detected by all colliding devices.
This collision subsequently delays retransmissions from those
devices for some random length of time. Ethernet and IEEE 802.3
use CSMA/CD access.
CT
Committed Time. The time interval used for measuring average
information transfer rates.
DHCP
Dynamic Host Configuration Protocol. A protocol for dynamically
assigning IP addresses from a pre-defined list to nodes on a network.
Using DHCP to manage IP addresses simplifies client configuration
and efficiently utilizes IP addresses.
DL
Down Link
DOS
Disk Operating System
DRAP
Dynamic Resources Allocation Protocol
DSCP
Differentiated Service Code Point, AKA DiffServ: An alternate use for
the ToS byte in IP packets. Six bits of this byte are being reallocated
for use as the DSCP field where each DSCP specifies a particular
per-hop behavior that is applied to the packet.

DLI Data Loss Indicator
EIR Excess Information Rate. Specifies the excess rate (above the
committed rate) of information that can be available to a user. The
EIR is used by the traffic policing mechanism to prevent users from
sending excess traffic to the network. (EIR = MIR-CIR).
EMC
Electro-Magnetic Compatibility. The capability of equipment or
systems to be used in their intended environment within designed
efficiency levels without causing or receiving degradation due to
unintentional EMI (Electro Magnetic Interference). EMC generally
encompasses all of the electromagnetic disciplines.
ETSI
European Telecommunications Standards Institute. A non-profit
organization producing voluntary telecommunications standards
used throughout Europe, some of which have been adopted by the
EC as the technical base for Directives or Regulations.
