Abstract

Recently, coordinationmiddleware systemshave evolved in order to describe coordination protocols in business process scenarios. This evolution proposes the use of three main components, being one of them a message broker to handle collaborative interactions among business processes. In a previous work, we proposed a framework for coordination in open BPM systems which used a centralised Linda-based implementation of amessage broker. The use of a centralised implementation leads to some common problems which a distributed model tries to solve in an efficient manner. In this paper, we present DRLinda, a distributed and dynamic implementation of the message broker based on the RLinda model, which improves and extends the RLinda's features and can be configured at run-time, being suitable formore complex and highly-dynamic business process scenarios. The performance of the proposed implementation is empirically evaluated on a cluster computing environment.
