This new approach can be mastered simply, run with high efficiency, and be expanded or extended easily. As network technology is developing rapidly and is applied more and more widely, a simple software architecture running in a network environment is of great practicability. Primarily, both the network technique and object-oriented technique are taken into account. Some of the advantages of this method compared to other methods are given also. An application of this approach in an exact sample is discussed.","PeriodicalId":248775,"journal":{"name":"Proceedings 2000 International Workshop on Autonomous Decentralized System (Cat.

Even though computing and telecommunications technologies are continuously improving, critical business applications foster an urgent need for high-assurance in information service systems. One solution has been proposed in the form of a distributed service replica network sustained by push/pull mobile agents, and called faded information field (FIF). In this system, user requests are autonomously driven by Pull-MA in charge of finding the relevant service. In the case of a mono-service request, the system is designed to satisfy heterogeneous requirements of both user and service provider. Under complex multi-service requests, users require that the heterogeneous services be available simultaneously to synchronize their actions. However, SPs have heterogeneous requirements for consistency and reliability that limit their distribution expansion. It is necessary to alleviate user transaction time when accessing various services. To solve this problem, this paper first proposes an autonomous integration mechanism of heterogeneous FIFs on the basis of correlation conditions. Next, optimization of the synergetic effect is realized through a heterogeneous information fading technique. The effectiveness of integrated services is then shown by simulation.","PeriodicalId":248775,"journal":{"name":"Proceedings 2000 International Workshop on Autonomous Decentralized System (Cat.

However, when the system has a complicated topology, such as a loop topology or mesh topology, the proposed A2PC method is not applicable. Because the A2PC assumes that the system has a straight or tree topology, it means that the terminator of the system is existent. In order to realize A2PC by ADS technology how to determine the terminator of the system must be resolved. Furthermore, while the system presents a topology without a terminator the transmission of commitment data in the system falls into circulating status. Due to this, in order to avoid circulated data transmission in the system, the autonomous message routing restraint technique becomes necessary. It means that the logical terminator must be determined by each system autonomously and dynamically according to the circumstance. In this paper, an autonomous topology recognition technique is proposed. It shows how to recognize the physical and logical terminator in the system.","PeriodicalId":248775,"journal":{"name":"Proceedings 2000 International Workshop on Autonomous Decentralized System (Cat.
