....usually consist of a hybrid approach, integrating both fixed and mobile components. Hence, we design the architecture with the following design goals in mind: # The architecture has to have an open design to enable the integration of some of our existing technologies and tools such as [11, 12, 17, 20]. # The architecture has to be generic enough to be deployed in organizations with varying internal organizational structures, business processes and IT infrastructures. # The architecture has to be scalable for different number of users, future extensions and new requirements. # The ....

....in designing the architecture to keep it flexible and scalable. 3. MOTION technology overview The MOTION platform aims at integrating different, innovative technologies and in particular the physical mobility of hosts connected to the wireless networks. Mobility of services, push technology[11, 12] and the eXtensible Markup Language (XML) 26] play an important role in the system. In this section, we give a brief overview of the technologies and concepts that are used in MOTION, and discuss several mobile working concepts we defined based on the organizational requirements. 3.1. User ....

....of command and alert dissemination in survivability architectures for very large distributed systems. 3. Decoupled Communication of Events Scalable event dissemination architectures are designed to target event delivery accurately in large distributed systems through event push architectures [5, 9]. Decoupled event systems are a subclass of event delivery push systems. Decoupling [6] is the operability of event communications without the requirement that senders or receivers know about each other s quantity, location, or state instantiation. Decoupling can have multiple forms [5] but we ....

....which are also interested in this payment s completion can subscribe to the same event type and also receive data of interest, e.g. copies of the receipt. This mechanism facilitates highly dynamic interactions but still provides separation of concerns. Part of the Opelix system is the Minstrel [18] push system which provides some basic services like content delivery and dissemination, and the payment framework as well. In the current implementation of the Opelix system, the payment component needs only to mediate between the requests from the business work flow process and the Minstrel ....

....business model. Thus before describing the architecture of the implementation an overview of Minstrel is given for the reader to understand the integration into an existing application. A detailed discussion of push systems in general and a description of Minstrel in particular are provided in [18]. Detailed description of di#erent parts of the Minstrel project can be found in [16] 44] 5.1 Minstrel Overview In contrast to the widely used request reply model, where a client actively pulls information from the server, a push system has a receiver (Consumer) which subscribes to an ....

....content delivery will be a premier feature in these systems [7] Additionally, wide acceptance will depend on the delivery of highly personalized and customized content. In this paper we investigate the features of a mobile push system. We build upon previous work in the Minstrel push system [8]. Minstrel enables P S style interaction between publishers who announce content and subscribers who have declared their interest in particular content types. The current Minstrel implementation only supports stationary users and a natural further step is to enhance it for mobile users. This ....

....subscribers. One approach is to employ IP multicast [12] but only a limited number of users have access to a multicast network. Another approach is to use point to point communication at the network layer and an application layer network of servers for content routing as is done in Minstrel [8]. Minstrel uses a two phase dissemination approach to address scalability: In phase 1 ( advertising ) the system distributes announcements to advertise content. If the announcement is interesting, a subscriber may request the delivery of the actual content in phase 2 ( delivery ) The advertising ....

In Minstrel a producer of information announces the availability of different types of information. Whenever new information becomes available it is sent from the producer to the subscribed users. The sender (producer) may be interested in charging the subscribers for this service data. A ....

....is fully compatible with it. It can be used with any Java code and in any environment which is compatible with Java 2, for example, in Java based mobile agent systems or for extended applet security features in Web browsers. JSEF originally was developed as part of the Minstrel push system project [8] to provide a flexible security environment for executable channel content (so called pushlets) and agents [9] This paper is organized as follows: Section 2 provides an overview of Java s security model. This model is discussed in Section 3 and we point out its shortcomings which provided the ....
