Advanced Network Device Layer/Software
Term for the Device Driver level.
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.
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.
API
See "Application Programming Interface" on page 2.
Application Programming Interface
An API is an interface used by an programmer to interface with functions provided by an application.
ARP
See "ADSL" on page 1.
Auto-negotiation
A feature that allows twisted-pair ports to advertise their capabilities for speed, duplex and flow control.
When connected to a port that also supports auto-negotiation, the link can automatically configure itself to
the optimum setup.
Auto Uplink
Auto Uplink technology (also called MDI/MDIX) eliminates the need to worry about crossover vs.
TM
straight-through Ethernet cables. Auto Uplink will accommodate either type of cable to make the right
TM
connection.
B
Backbone
The part of a network used as a primary path for transporting traffic between network segments.
