Equalizer Installation and Administration Guide 207
Secure Sockets Layer (SSL) A protocol, which uses public-key encryption, that enables secure
communications between a client and Web server, typically for guarding
financial transactions.
server A computer or application that controls access to a network and its associated
devices and applications. A server communicates with one or more clients as
well as other servers. See authoritative name server, back-end server, name
server, physical server, proxy server, and virtual web server.
server address The IP address of a server on the internal interface. Multiple IP addresses can
be aliased to a single physical server. See server.
server agent An agent that provides Equalizer with real-time performance statistics for a
specified server. See server.
server cluster A group of servers that are components in a network and joined through
hardware or software. See cluster. See also FTP cluster, geographic cluster,
and virtual cluster. See server.
server endpoint An IP address-port pair that identifies a physical or virtual server on the internal
network to which Equalizer can route connection requests. See server.
server weight A value that indicates the relative proportion of connection requests that a
particular server will receive. See dynamic weight, server, static weight, and
weight.
session A logical connection between a server and a client that spans a series of
individual client requests and server responses. The persistence of session
data is maintained through the exchange of cookies in Layer 7, or through the
sticky connections feature in Layer 4.
site A cluster of servers under Equalizer control that is part of a geographic cluster.
spoofing Fooling a system into thinking that a transmission comes from an authorized
user when that may not be the case.
SSL See Secure Sockets Layer (SSL).
stack An area of reserved memory in which applications place status data and other
data. See protocol stack.
stale connection A partially open or closed connection.
state Status; the current condition of a network, computer, or peripherals.
stateless A condition in which a server processes each request from a site
independently and cannot store information about prior requests from that site.
Each request stands on its own. See also DNS and RADIUS.
static 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
static weight originally set by the administrator. See dynamic weight, server
weight, and weight.
sticky connection A connection in which a particular client remains connected to same server to
handle subsequent requests within a set period of time.
sticky timer A countdown timer that tracks periods of inactivity between a particular client
and server.
subdomain A section, which is formally named, that is u
nder a domain name; analogous to
the relationship between a subfolder and folder. For example, in
www.coyotepoint.com, www is the subdomain. See domain, domain name,
and IP address. See also DNS.
subnet Part of a network that has the same address as the network plus a unique
subnet mask.
