example, stating that a GET request to a resource should returns the complete reply body in 

one second from the time of issuing the request may not a reasonable if the amount of data in 

the reply body can vary from 1 Kb to 1 Mb. A more appropriate parameter in this case may 

be that the entity download rate is greater that 10 Kbps. 

3.6 Conclusion 

This Chapter first revisited the motivations of this dissertation and the primary objectives 

defined in Chapter 1. The use of HTTP as a service delivery mechanism was investigated, as 

were the potential sources of performance and availability issues. Leading from this, 

monitoring of HTTP delivered services and the parameters that such service monitoring 

should capture were defined. Finally the issue of how to monitor services so as to be able to 

capture the availability and performance as perceived by the end user was addressed.
