There are many different models to choose from and there are many forces influencing each model. We discuss five messaging models: Home-Proxy, Follower-Proxy, Email, Blackboard and Broadcast. We overview the forces that are the most important to all models and identify to what extent the forces influence the models. Our findings suggest that one should not use the Forwarder-Proxy model to build mobile agent systems. Instead, one should use the Blackboard approach, especially when agents require only anonymous messaging. In the case when anonymous messages cannot be used, your choice of model can be the Home-Proxy model, the Email model or the Broadcast model depending on which forces are more important to your application.","PeriodicalId":193918,"journal":{"name":"Proceedings 5th International Symposium on Autonomous Decentralized Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121933959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a dynamic replica distribution model, which replicates shared object replicas adaptively according to user requirement as well as dynamic cooperation context. A replicating structure between fully-replicated and fully-centralized ones is achieved through the process of structural adaptation; concurrency adaptation is also used to achieve a multi-replica consistency policy between traditional optimistic and pessimistic paradigms. XML is used as the underlying support layer for representing the structures and contents of shared cooperative objects.","PeriodicalId":193918,"journal":{"name":"Proceedings 5th International Symposium on Autonomous Decentralized Systems","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130391178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to find back resources and to interconnect applications, the middleware has to provide a trading function. Unfortunately, standard traders such as the ODP/OMG CosTrading service, are error-prone due to the lack of type checking at compilation time, but only performed at runtime. In order to address this problem, we have defined the Trader Oriented Request Broker Architecture (TORBA) to provide a trading framework and its associated tools, which tend to offer type-safe trading operations that are simple to use from applications and checked at compilation time. Based on the concept of Trading Contracts, a resource is described using the TORBA Definition Language, and then compiled to generate trading proxies offering simple interfaces to applications. The example used in this paper clearly states the benefits brought by the TDL trading contracts: type checking at compilation time, simple to use, and providing a powerful and reliable framework for CORBA object trading.","PeriodicalId":193918,"journal":{"name":"Proceedings 5th International Symposium on Autonomous Decentralized Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129197821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Software implemented fault-tolerant protocols are used to support dependable computing. This paper first presents Markov models of a distributed system under the occurrence of faults, reconfiguration and repair. As a part of our overall project, these models are intended for solving our particular problems, like assessing the merits of redundant schemes, task allocation and reallocation policies, and fault handling used in our experimental system. However, these models are developed in a generic way. They can also be used in evaluating individual task's reliability, risk and availability under various redundant schemes in any homogeneous distributed system. Then, we extend our study in analysing the dependability of the heterogeneous system consisting of a number homogeneous distributed systems connected through gateways.","PeriodicalId":193918,"journal":{"name":"Proceedings 5th International Symposium on Autonomous Decentralized Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124333877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Users currently have trouble using multiple EC services because they are provided independently. Therefore a mediator that combines EC services and provides one-stop services to users would be useful. Service matching and service collaboration are important issues in the mediator because they are the main difficulties for users. The proposed architecture provides solutions to these issues. Multiple service assignment provides suitable combinations of EC services, flow division enables efficient execution of the combined EC services, and dynamic alternative service assignment enables flexible failure avoidance during the execution of combined services. These features make the proposed architecture a suitable mediator for EC services.","PeriodicalId":193918,"journal":{"name":"Proceedings 5th International Symposium on Autonomous Decentralized Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124764903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is particularly true in the rapidly evolving world of e-commerce, which raises the challenge of building software systems that are flexible enough to support such a dynamic business environment. Previously (O. Stiemerling et al., 1999), we presented the EVOLVE runtime- and tailoring environment as a platform for extensively adaptable autonomous and decentralized systems. The platform provides a high degree of flexibility by maintaining the component structure of such systems. One can (during runtime and in a decentralized fashion), add, exchange or rewire an application's components to meet changing external requirements. While the EVOLVE platform provides the mechanisms to perform these changes, there remains the problem of providing an administration interface to these mechanisms. Like many autonomous and decentralized systems, EVOLVE applications can have great complexity and structural detail. The interface has to present these details in an appropriate and scalable form, permitting the administrator to quickly grasp the overall distribution structure, but also the functional details and fine grained components. The authors argue that 3D visualization and manipulation techniques provide a good basis for the design of administration interfaces for complex, decentralized systems. We support our argument by presenting a 3D interface for the EVOLVE platform and discuss the more general design concepts it embodies. These concepts are relevant and applicable to other autonomous and decentralized systems.","PeriodicalId":193918,"journal":{"name":"Proceedings 5th International Symposium on Autonomous Decentralized Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114237815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a negotiation protocol between two participants, as well as the similarity measures which were implemented to find a similar product when a specific one could not be found. The proposed protocol follows the bilateral model approved by the OMG. The negotiation model is composed of selling and buying Grasshopper mobile agents, which negotiate between themselves in order to get the best deal. The negotiation of the price is based on the Kasbah model. The catalogs in the model are implemented in XML to provide the interoperability among different systems.

We present protocols and architecture for e-service brokering communities, and discuss their use in workbase, an Internet-based, automated workflow system over e-services. The brokering protocols are based on a three-tier architecture of agents, brokers and superbrokers. We also present an infrastructure for dynamically composing new services from exiting e-services on the Internet. An implementation using JKQML of brokering communities is provided along with the architecture and design of our e-services and workflow concepts.","PeriodicalId":193918,"journal":{"name":"Proceedings 5th International Symposium on Autonomous Decentralized Systems","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124132611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
