ICMP Probes
These are Server Health Checks. ICMP health checks basically have Equalizer sending a "ping" to a server and "listening" if the
server sends a response. If the server does not respond within the configured time, the server is marked "down" and no further
traffic is sent to that server until it starts responding to health checks.
ICMP triangulation
Routing client requests to the closest site geographically based on triangulation, a method of calculating the location of a site using
the known locations of two or more other sites.
initial weight
The weight that an administrator assigns to a particular server. During operation, Equalizer dynamically adjusts the server weights
(that is, dynamic weight), so a server’s weight at a particular time might be different from the initial weight originally set by the admin-
istrator. See dynamic weight, server weight, and weight.
intelligent load balancing
A request for load balancing using Equalizer-based algorithms that assess the configuration options set for cluster and servers,
real-time server status information, and information in the request itself. See algorithm and load balancing. See also geographic
load balancing.
interface
The place at which two or more systems connect and communicate with each other. See external interface, internal interface, and
network interface.
internal address
The IP address assigned to Equalizer on the internal network.
internal network
The subnet to which the back-end server machines are connected.
Internet Control Message Protocol (ICMP)
The ISO/OSI Layer 3, Network, protocol that controls transport routes, message handling, and message transfers during IP
packet processing. See ICMP triangulation and ISO/OSI model.
IP
Internet protocol; the TCP/IP protocol that controls breaking up data messages into packets, sending the packets, and reforming
the packets into their original data messages. See Internet protocol stack, IP address, packet, and TCP/IP.
IP address
A 32-bit address assigned to a host using TCP/IP. IP addresses are written in dotted decimal format, for example, 192.22.33.1.
IP Reputation Database
An IP Reputation database aggregates data from locations and sources around the world that collaborate to provide up to date
information about threatening sources. It is commonly used as protection against malicious sources associated with web attacks,
phishing activity, web scanning.
IPv4
Internet Protocol version 4 (IPv4) is the fourth revision in the development of the Internet Protocol (IP) and the first version of the
protocol to be widely deployed. Together with IPv6, it is at the core of standards-based internetworking methods of the Internet.
IPv6
IPv6 (Internet Protocol version 6) is a version of the Internet Protocol (IP) intended to succeed IPv4, which is the protocol currently
used to direct almost all Internet traffic.[1]
IPv6-IPv4 Translation
IPv6-IPv4 Translation is used when a portion of an internal network only supports IPv4 and/or a portion of applications can accept
only IPv4 connections. The advantage of this is that IPv6 to IPv4 translations are provided for legacy IPv4 application services and
