this connection would exhibit some variations in the responses and perhaps connection 

failures would occur which would highlight the monitoring capabilities of the proxy. Of 

course, dropping the Internet connection could simulate failures connecting to the service if 

required to generate appropriate logs. 

The services list and the SLA for the service, which will be discussed next, were placed on a 

Web server running on the same host that the proxy runs on. This would not be the typical 

scenario in that the proxy would normally be configured to connect to the SLAVSP, identify 

the customer and be returned the appropriate list of services to manage. For each service, the 

appropriate SLA would then be retrieved if not already stored locally. However it was 

sufficient in this case to use the local Web server and static XML files to store the services 

list and SLAs so as to demonstrate the operation of the framework.
