Reference Manual for the 54 Mbps Wireless Router WGR614 v4
2 Glossary
December 2003
ADSL
Short for asymmetric digital subscriber line, a technology that allows data to be sent over existing copper
telephone lines at data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and
from 16 to 640 Kbps when sending data (known as the upstream rate).
ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world
gain access.
AES
Advanced Encryption Standard, a symmetric 128-bit block data encryption technique.
It is an iterated block cipher with a variable block length and a variable key length. The block length and the
key length can be independently specified to 128, 192 or 256 bits.The U.S government adopted the
algorithm as its encryption technique in October 2000, replacing the DES encryption it used. AES works at
multiple network layers simultaneously.
AH
Authentication Header.
ARP
Address Resolution Protocol, a TCP/IP protocol used to convert an IP address into a physical address (called
a DLC address), such as an Ethernet address.
A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host
on the network that has the IP address in the request then replies with its physical hardware address. There is
also Reverse ARP (RARP) which can be used by a host to discover its IP address. In this case, the host
broadcasts its physical address and a RARP server replies with the host's IP address.
Auto Uplink
Auto Uplink
TM
technology (also called MDI/MDIX) eliminates the need to worry about crossover vs.
straight-through Ethernet cables. Auto Uplink
TM
will accommodate either type of cable to make the right
connection.
CA
A Certificate Authority is a trusted third-party organization or company that issues digital certificates used
to create digital signatures and public-private key pairs.
Cat 5
Category 5 unshielded twisted pair (UTP) cabling. An Ethernet network operating at 10 Mbits/second
(10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be
rated as Category 5, or Cat 5 or Cat V, by the Electronic Industry Association (EIA).
This rating will be printed on the cable jacket. Cat 5 cable contains eight conductors, arranged in four
twisted pairs, and terminated with an RJ45 type connector. In addition, there are restrictions on maximum
cable length for both 10 and 100 Mbits/second networks.
