The actual probability achieved in practice depends on the strength of the ....

The basic model is similar to that of the World Wide Web; documents are available on a server and are retrieved via a browser.

....the UTL API when its more advanced features are not required for a given application. As an example of a fallback, consider the notion of a service profile. The UTL API allows an application to specify a service profile, which is a data structure defining a partial order and reliability vector [7]. The service profile is only used when the underlying protocol supports partial order and partial reliability. If the application has no need to take advantage of such features, it can ignore the parts of the API which allow the service profile to be specified. In this case, a default partial ....
