Downstream
Download / downstream denotes the direction of dataflow in a WAN. Downstream is the
direction from the head end or Internet to the participant connected to the network.
DS Distribution System
DSL Digital Subscriber Line - DSL procedures include all procedures for digital-broadband use
of telephone lines, such as ADSL, HDSL, SDSL, VDSL and so on, which are also called
xDSL.
DSSS Direct Sequence Spread Spectrum; code multiplex -- band spreading process
Dynamic DNS IPsec-VPN implementation which allows the transparent connection of local networks
into a VPN solution, even when their routers work with dynamic addresses (dial-up)
EAP Extensible Authentication Protocol
EAP-MD5 EAP variant which uses password for one-sided authentication
EAP-TLS EAP Transport Layer Security; EAP variant which uses certificates for mutual authentica-
tion
EAP-TTLS EAP Tunneled Transport Layer Security; EAP variant which uses certificates for mutual
authentication
EIRP Effective Isotropic Radiated Power
ESS Extended Service Set
ESSID Extended Service Set Identity; “network name" of the wireless LAN
Ethernet Strand or star-formed physical transport medium; all stations can send simultaneously;
collisions are detected and corrected through the network protocol
FHSS Frequency Hopping Spread Spectrum; frequency skipping band spread procedure
Firewall Protective mechanism for an Intranet against attacks from outside
Frequency Number of oscillations per second (given in Hertz; 1 Hz = 1 oscillation per second; GHz =
Gigahertz = 1 billion Hertz or oscillations per second)
FTP File Transfer Protocol enables data transfer between different systems and simple file
manipulation; FTP is based on the TCP transmission protocol
Frequency band Contiguous frequency range which has the same transmission properties
Radio frequency Every radio application uses globally regulated radio frequencies
Gateway Network component which provides access to other network components on a layer of
the => OSI model. Packets which do not go to a local partner are sent to the gateway.
The gateway takes care of communication with remote networks.
Hub Network component; distributor; collector; also used to translate from one connection
type to another
HotSpot Locally limited wireless network with a base station with Internet access; public wireless
Internet access
IAPP roaming Roaming between the cells of a wireless network using IAPP (Inter Access Point Proto-
col)
IBSS Independent Basic Service Set
IDS Intrusion Detection System -- earliest possible detection of attacks on the network
IEEE Institute of Electrical and Electronics Engineers, New York - www.ieee.org
IP Internet Protocol
IP masquerad-
ing
Combination of PAT (Port Address Translation) and NAT (Network Address Translation)
from Hirschmann process used for connection of an intranet (multiple workstations) to the
Internet over a single IP address; simultaneously, the internal computers are protected
from attacks from outside
IPSec Internet Protocol Security
