Any HP-UX
Enterprise
Server running
on HP-UX 11.x
and running a
web server that
is managed by
WebQoS.
Collects performance information from the
Service Resource Controller and WebQoS
request control. Receives management
control directives from the Service Control
Operator. Distributes configuration
information to WebQoS nodes. The SCA
monitors operation information and gives
feedback to the SCO. This information is
displayed by the management user interface.
This component includes the following
sub-components:
Session Manager—creates sessions and
tracks activity within a session until it
expires.
Classifier—examines attributes of a service
request to determine the appropriate request
classification assignment for the request.
Admission Controller—monitors system load
and response time in order to decide whether
or not new sessions are accepted.
Scheduler—submits service requests to the
web server based on each request's assigned
request classification priority.
Class Encoder/Decoder—encodes and
decodes the request classification priority for
requests and responses into network packet
headers so that network devices can handle
these accordingly.
