Glossary
administration address
The IP address assigned to Equalizer on any VLAN. Access to Equalizer can be configured for each VLAN.
administration interface
The browser-based interface for setting up and managing Equalizer.
affinity
Affinity is a technique that enables the load balancer to remember which balanced server was chosen for a certain client at its initial
request. Subsequent requests are then directed to the same server again. If the affinity feature is disabled when a new TCP/IP con-
nection is received from a client, load balancer chooses the correct server at that moment and forwards the packet to it. If a sub-
sequent connection comes in from the same client, load balancer treats it as an unrelated connection, and again chooses the most
appropriate server at that moment.
agent
An application that gathers or processes information for a larger application. See server agent.
agent weight
The relative influence on the policy of the return value of a server agent (if any) running on the servers in the cluster.
aggregation
See link aggregation and sticky network aggregation.
algorithm
Instructions, procedures, or formulas used to solve a problem.
alias
A nickname that replaces a long name or one that is difficult to remember or spell.
aliased IP address
A nickname for an IP address.
Application Delivery Controller (ADC)
An application delivery controller (ADC) is a network device that usually sits between the firewall/router and application servers.
The ADC is in many cases described as the next generation load balancer.
application layer
Layer 7 of the Open Systems Interconnection (OSI) network model, where communication between endpoints is defined by the
application.
atom
The smallest part of a regular expression in Equalizer. See branch, piece, and regular expression.
authoritative name server
A name server that maintains the master records for a particular domain. See name server.
B
back-end server
A physical server that is part of a virtual cluster on Equalizer.
backup Equalizer
The backup unit in a failover pair of Equalizers. The backup unit constantly monitors the health of the active (primary) unit, and
replaces the primary unit in the event that the primary becomes unavailable. See hot backup and primary Equalizer.
