| Popis: | Service selection in Service-oriented computing (SOC) is an important step towards obtaining the required level of quality. Fault-Tolerance Techniques (FTT) can be used to enhance the reliability of compositions considering Quality of Service (QoS) requirements. Services that do not perform as expected must be replaced by equivalent services. We propose a mechanism called FTT Service Selector (FSS) to select services that meet QoS constraint values defined by the user. FSS uses a Constraint-Satisfaction Problems (CSP) approach to generate a global optimal service selection. Experiments show that FSS can be used to generate solutions to form compositions with up to ten roles and ten equivalent services. In most cases, FSS can generate solutions in a feasible time. |
