ABSTRACT	If the number of users within a workflow management system (WFMS) increases, a central workflow server (WF-- server) and a single local area network (LAN) may become overloaded. The approach presented in this paper describes an execution environment which is able to manage a growing number of users by adding new servers and subnets. The basic idea is to decompose processes into parts which are controlled by different WF--servers. That is, during the execution of a workflow instance its execution (step) control may migrate from one WF--server to another. By selecting the appropriate physical servers (for hosting the WF--servers) in the appropriate LANs, communication costs and individual WF--server workload can be reduced significantly. 1. Introduction Since a couple of years there has been a growing interest in using WFMS for implementing process--oriented application systems. As the benefit of such application systems increases with the number of applications being served, the number...	user correction - Legacy Corrections
