Service Providers in Service-Oriented Architectures (SOA) often specify system performance values with the help of Service Level Agreements (SLAs) that do not specify details of how the system realizes services. Analytic modeling of SOA to estimate performance values is thus made difficult without knowledge of service rates. Service components are characterized by quantitative requirements in SLAs only, that are not supported by most modeling methods. We propose a calculus to model and evaluate SOA with quantitative properties described in SLAs. Instead of defining a system by its service capacity we will use flexible constraints on delays as found in SLAs. From these delays approximate service rates to fulfill the delay will be derived.
