Using Symbolic Dates of the Linear Logic to Verify Performance Requirements in SOA Models

Abstract

This article presents an approach for performance verification of requirement scenarios in Service-Oriented Architecture (SOA) models. The SOA models are represented by Interorganizational WorkFlow nets that are not necessarily deadlock-free. The requirement model considered in this article defines functionalities that are of interest of all parties involved in the process, for this reason is considered as a public model. An architectural model is considered as a private model since it is composed of a set of private processes that interact through asynchronous communication mechanisms. For the scenarios of the architectural and requirement models that are equivalent in terms of behaviour (or bisimulation) symbolic dates associated with the activities of the processes can be produced from the calculation of the Linear Logic sequents. Symbolic dates can be used to verify if an architectural model scenario that simulates the behavior of a requirement model scenario is also equivalent in terms of performance. To illustrate the proposed approach an example was considered and from this example it was possible to observe that the approach can be useful to indicate if a architectural model in the context of SOA satisfy the performance of business needs defined by a requirement model.
