HP WebQoS Software manual 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.
