protocol stack A layer of protocols that process network actions cooperatively and in tandem.
See protocol.
proxy server A utility, which is part of a firewall, that helps the regular tasks of managing
data transmittal from a network to the Internet and from the Internet to the
network. See also firewall.
quiesce Quiesce is a server option that, when enabled, tells Equalizer not to send the
server any new traffic, while existing connections are allowed to complete.
Eventually, the server should not be serving any traffic. Sometimes called
‘server draining’.
RADIUS Remote Authentication Dial-In User Service; a protocol that authorizes and
authenticates a user trying to link to a network or the Internet.
redirection The process of receiving input from or sending output to a different resource
than usual.
regular expression (RE) One or more non-empty branches, separated by pipe symbols
(|)
. An
expression matches anything that matches one of the branches. See atom,
branch and piece.
request packet A packet that contains information that requests a response. See packet and
response packet.
reserved network A network consisting of “phony” IP addresses, which are not registered and
cannot be made visible outside of the internal network.
resolution The process of interpreting all the messages between an IP address and a
domain name address.
response packet A packet that contains information that responds to a request. See packet and
request packet.
round robin The default load balancing policy which distributes requests equally among all
servers in a virtual cluster, without regard to initial weights or adaptive load
balancing criteria. The first request received is routed to the first server in the
list, the second request to the second server, and so on. When the last server
is reached, the cycle starts again with the first server.
router A network device that facilitates the transmission (that is, routing ) of
messages.
routing table A database, which is static or dynamic, that contains a set of route addresses
and routing information familiar to the router. A human being enters and
updates the information in a static routing table; routers operate and
constantly update a dynamic routing table.
RST Refers to the TCP protocol’s reset command, which instructs a device to end
a connection.
Secure Sockets Layer (SSL) A protocol that enables secure communication between two hosts, using data
encryption and authentication.
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.
