HTTPS HyperText Transfer Protocol (Secure). The SSL/TLS protocol is used in
combination with the HTTP protocol to provide secure identification and data
encryption.
hub A device that joins all the components attached to a network.
ICMP See Internet Control Message Protocol.
ICMP echo request The act of repeating a stream of characters (for example, echoing on the
computer screen characters as a user types those characters). See ping. See
also echo.
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 administrator. 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,
