How WebQoS Fits Into Your Environment
WebQoS, which includes a set of extensions to HP-UX, works with your
web server and application servers for all of your web-enabled
applications. Refer to Figure 1-1, "WebQoS in Your Environment".
Figure 1-1 WebQoS in Your Environment
To ensure acceptable web-based interactions between you and your
customers, all parts of your web environment (client, network, web
server, and application server which includes an application) must work
together efficiently and effectively. The network alone cannot deliver
acceptable service levels if the server is creating delays due to excessive
demand or component failures. The server alone cannot deliver
acceptable service levels if the network is exhibiting bottlenecks.
The following describes briefly the function of each part of the
environment:
• The client identifies itself and initiates requests.
• The network distinguishes class priorities and routes priority packets
efficiently while delivering best effort service to lower priority
packets.
• The web server distinguishes WebQoS request priorities and
manipulates operating system scheduling policies and resource
management policies to ensure high priority service requests are
processed quickly.
• The application server contains an application with the processing
rules that enables service requests to be classified and handled by the
server and network.
