such, the monitoring can take place independently of the Service Provider once the SLA 

has been given to the SLAVSP. Of course if the Service Provider requires feedback from 

the Customer, the necessary hooks will have to be put in place for the Service Provider 

to use. 

Being able to measure the QoS of a Web delivered service as perceived by the end user 

allows truly meaningful Service Level Agreements to be defined between the Service 

Provider and the Customer. 

The framework suggested in this dissertation is a flexible architecture that allows 

multiple services from multiple service providers to be monitor using the same proxy 

while also allowing feedback to the service provider via a SLAVSP. 

The location of where SLA verification and analysis are done can be distributed in the 

framework suggested, as the SLA 

and

 service usage data are available to the client side 

proxy.
