Authentication, Authorization, and accounting. Authentication confirms the identity of the user or device. Authorization determines what the user or the device is allowed to do. Accounting records the information about the access attempts, including inappropriate attempts.
AAA
A server that holds security information and provides services related to user login, particularly authentication, authorization, and accounting.
AAA Server
A router using OSPF in which the router has interfaces in multiple OSPF areas.
Area Border Router (ABR)
A LAN network design that refers to a switch interface connected to end-user devices, configured so that it does not use VLAN trunking.
Access Interface
In a campus LAN design, the switches that connect directly to endpoint devices, and also connect into the distribution layer switches
Access Layer
A device that provides wireless service for clients within its coverage area or cell
Access Point (AP)
In security, the recording of access attempts
Accounting
An impromptu wireless network formed between two or more devices without an AP or a BSS
Ad Hoc Network
A set of consecutive IPv4 addresses
Address Block
The general topic of how, on one computer, two adjacent layers in a network architectural model work together, with the lower layer providing services to the higher layer
Adjacent-Layer interaction
A means for one router to choose between multiple routes to reach the same subnet when those route were learned by different routing protocols.
Administrative Distance
One of many DSL technologies, designed to deliver more bandwidth downstream than upstream
Asymmetric Digital Subscriber Line (ADSL)
A specific IPv6 multicast address, FF02::1, with link-local scope, used to send packets to all devices on the link that supports IPv6
All-Nodes Multicast Address
A specific IPv6 multicast address, FF02::1, with link-local scope, used to send packets to all devices that acts as IPv6 routers on the local link.
All-Router Multicast Address
With RSTP, a port role in which the port acts as an alternative to a switch’s root port, so that when the switch’s root port fails, the alternate port can immediately take over as the root port.
Alternat Port
An address shared by two or more hosts that exist in different parts of the network, so that by design, the routers will forward packets to the nearest of the two servers, allowing clients to communicate with the nearest such server, not caring which particular server with which the client communicates.
Anycast Address.
A router using OSPF in which the router has interfaces in multiple OSPF areas
Area Border Router (ABR)
An internet protocol used to map an IP address to a MAC address. Defined in RFC 826
Address Resolution Protocol (ARP)
A list of IP addresses of neighbors on the same VLAN, along with their MAC addresses, as kept in memory by hosts and routers.
ARP Table
The first packet-switched network, first created around 1970, which served as the predecessor to the internet.
ARPANET
