Service Discovery with Cost Thresholds

Abstract

In a service-oriented architecture, business processes are implemented as interacting services. During service discovery, a service requester N queries a service broker for a compatible service provider. Compatibility criteria exist on different levels, among others behavior and non-functional properties. For several behavioral compatibility criteria the problem to find a compatible service provider has been solved. In this paper, we tackle the case of non-functional compatibility.

In particular, we study cost thresholds. Intuitively, the costs for the service requester to interact with a compatible service provider stay below a given threshold. Thereby, costs are an abstract concept, representing a variety of non-functional properties as for instance execution costs, execution time, reliability or energy consumption. We contribute a formal framework to model such costs based on semirings. Additionally, we present first results in the field of analysis. Thereby, we focus on enabling the reuse of existing analysis techniques for behavioral criteria.
