Abstract
In large workflow management systems (WfMS), it is particularly important to control workflows (WF) in an efficient manner. A very critical factor within this context is the resulting communication overhead. For this reason we have developed an approach for distributed WF control, which tries to keep the communication overhead low. In this paper, this approach is described and examined by means of a simulation. 1 Introduction Enterprise-wide and cross-enterprise WF scenarios are characterized by a large number of users and many concurrently active WF instances. Therefore, the WF servers have to cope with a high load in total. Furthermore, in such an environment, the different organizational units (OU) are often far away from each other and connected by slow wide area networks (WAN). For this reason, the load of the communication system is an extremely critical aspect. Because of the resulting communication overhead a centralized WF control is often not applicable (at least not at rea...
