Managing and Pricing Service Level Agreements for Di erentiated Services
We present an approach to manage and price service level agreements (SLAs) for di erentiated services that uses a simple upper bound for the e ective bandwidth of the conforming tra c as a proxy for resource usage. The bound depends on the user's tra c pro le (peak rate and token bucket descriptor). Usage charges for a speci c time period are proportional to this proxy, and their calculation re...

متن کاملModeling of Service-Level Agreements for Composed Services
As Web services are increasingly accepted and used, the next step for them is the development of hierarchical and distributed services that can perform more complex tasks. In this paper, we focus on how to develop guarantees for the performance of an aggregate service based on the guarantees provided by the lower-level services. In particular, we demonstrate the problem with an example of an e-...
