service-oriented request
classification - A request
classification that focuses on the
destination (specific module or
content) of a request.
session - In WebQoS, a session is
composed of one or more requests
to a web site. These requests may
arrive over one, or possibly several
connections. Once a session has
been granted, a user’s remaining
requests are guaranteed to be
forwardedtotheweb server, unless
the session times out. Under
periods of heavy system load, it is
possible that new sessions will not
be granted. (This is driven by your
specific policies.) However, existing
sessions continue uninterrupted.
shared server/cluster -Asystem
or cluster of systems that host
services and content belonging to
several businesses or business
units.
T
threshold policy - An SLO
defined by an IT/ISP administrator
for the purposes of monitoring and
maintaining the health and well
being of the complex as well as
keeping critical services up and
running.This SLO is private to the
service provider and are distinct
from business SLOs which are
explicitlynegotiatedwithahosting
customer.
ToS byte - Type of Service byte in
the IP header. In RFC1812, it is
divided into three sections: the
precedencefield(high-order3bits),
a field that is customarily called
type of service or ToS (next 4 bits),
and a reserved bit (the low order
bit).
transparent classification - The
classification performed by
examining the attributes of a
request such as whom it came
from, where it is destined, or the
type of service for which the
request is constructed. The
application is unaware that the
classification has been performed
by WebQoS.
U
URL document path - The
directory path and filename of the
URL used to access the site. For
example, given the URL
http://some.system.domain.com/my
_path/index.html, the URL
document path is
/my_path/index.html
