....Tracy. 1 Motivation Over the past years, research in the area of mobile agent technology as a new paradigm of distributed programming has focused on suitable programming languages [5, 11] and languages for agent communication [1] Very much e ort was put into security issues [18] control issues [2,16], and in agent cooperation [13] Several prototypes of real world applications in the area of information retrieval, management of distributed systems, and mobile computing are in development [14, 15] To our understanding, a mobile agent is any kind of software entity that is able to initiate a ....

....Tandem server classes by Straer et al. 1997) In order to make mobile agents usable in a commercial setting, our current research investigates further extensions to the system infrastructure. In particular, methods for orphan detection and agent termination have been investigated by Baumann and Rothermel (1997), coordination of agent groups has been investigated by Baumann and Radouniklis (1997) an approach for securing agents against malicious hosts has been investigated by Hohl (1997) and a protocol for preserving the exactlyonce property of mobile agents by Rothermel and Straer (1997) ....

....the exactly once property as well as an increased level of fault tolerance. As we will see later, these requirements imply the integration of agent systems with transactional technology. Unfortunately, none of the currently available agent systems provide this type of functionality yet. In [9], a protocol for preserving the exactly once property of mobile agents has been proposed. With this protocol, agents are performed in so called stages. Each stage consists of a number of nodes. Each of these nodes adopts one of two possible roles, either the role of a worker or the role of an ....

....2 becomes unavailable for several hours while Paul s concierge agent visits this node, it may happen that the agent will not be able to fulfil its task in time even though this would be possible by just using the other ticket service. Therefore, an extension of this protocol has been proposed in [9] increasing the degree of fault tolerance. Here, we will confine ourselves to describing the basic principles of this protocol. 3.1 The Simple Protocol The exactly once property of mobile agents can be achieved in a simple way by using transactional message queues (e.g. see [4] Transactional ....
