HP WebQoS Administration Guide

144
differentiated access - Access
based on classification rules.
Requests associated with one
classification rule might be
admitted while those associated
with another are not.
differentiated performance -
Differentiated response time and
throughput achieved via queuing,
process control, and flow control.
Differentiation may be based on
request classifications.
I
IP precedence - Refers to the
precedence field in the ToS byte
(see ToS byte) in IP. See RFC 1812.
In WebQoS, the low-order 2 bits
are used.
L
load balancer - A network
element that directs traffic to
servers within a server farm based
on the current load being
processed by the servers.
M
management console - Allows
you to define performance
objectives for the components of
the service and to monitor
performance levels and SLOs.
N
network QoS protocols -
Protocols that are used for network
quality of service. For example, IP
ToS,RSVP, 802.1p,etc. Also known
as QoS behavior.
P
persistent connection - An
HTTP 1.1 feature in which a
connection established with a web
browser remains open for the
servicing of additional subsequent
requests coming from that browser.
priority - Request classifications
determine how quickly a request is
processed. Priorities are
designated as high, medium, or
low.
R
redirection - Redirection of a
session to a specified URL that has
WebQoS configured and running.
rejection - The decision not to
satisfy a user request. A rejection
is performed by an admission
controller, typically in response to
heavy load on the server. The user
may come back at a later time
when the server is less busy. The
rejection may contain special
incentives for the user to return
later, such as a personalized
promotion or an electronic coupon.
