In large part, NCW can be classified as a collective large-scale information dissemination system that operates at multitudes of levels and will be implemented using different distributed technologies and architectural styles. This paper classifies the use of these different distributed technologies as layers of information abstractions and highlights their varied architectural uses as they are driven by latency, scalability, reconfiguration and seamless programming requirements. For example, the following technologies are contrasted: Peer to Peer and mobile networks, Web Services, Content-based Routing, and Real-Time CORBA, while addressing distributed Security and Fault Tolerance issues. Unique challenges for when and how these technologies can be used, as well as their attributes for addressing scalability are highlighted. These technology challenges are classified and contrasted using the models based on the Siena project[2] which has been extended for the real-time community and termed Siena+RT. These requirements are described in context of the Boeing Phantom Works[8] XIS (eXtensible InfoSphere) Scalability Testbed Framework. XIS is a set of hierarchal distributed technologies developed to support the diverse real-time requirements for collection and dissemination of information throughout a global information grid.","PeriodicalId":204411,"journal":{"name":"Sixth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing, 2003.","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127955418","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}

However as the system evolves the possibility to predict the consequences of changes becomes more and more difficult unless models and analysis method can be used. Moreover, traditional real-time models, e.g., fixed priority analysis, may be too simple for accurately capturing a complex system's characteristics. For instance, assuming worst-case execution time may not be realistic. Hence, analyses based on these models may give an overly pessimistic result. In this paper we describe our approach to introducing analyzability into complex real-time control systems. The proposed method is based on analytical models and discrete-event based simulation of the system behavior based on these models. The models describe execution times as statistical distributions which are measured and calculated in the existing system. Simulation will not only enable models with statistical execution times, but also correctness criterion other than meeting deadlines, e.g., nonempty communication queues. The simulation result is analyzed by specifying properties in a probabilistic property language. The result of such an analysis is either of probabilistic nature or boolean depending on how the property is specified. Having accurate system models enable analysis of the impact on the temporal behavior of e.g., customizing or maintaining the software.","PeriodicalId":204411,"journal":{"name":"Sixth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing, 2003.","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115549853","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}

The), perform less favourably, however if the arrival times of some activities are not known in advance, in particular if overload situations have to be anticipated. In many systems, the criticality of only a subset of activities justify the cost associated with the time triggered methods. In this paper we consider distributed systems where a subset of critical activities are handled in a time triggered fashion, via an offline schedule. At runtime, the arrival of aperiodic tasks may cause overload that demands to be handled in such a way that i) time triggered activities still meet all their original constraints, ii) execution of high-valued tasks are prioritised over tasks with lower value, iii) tasks can be quickly migrated to balance the overall system load. We give a precise formulation of overload detection and value based task rejection in the presence of offline scheduled tasks, and present a heuristic algorithm to handle overload. To benefit from the distributed setting, the overload handling includes an algorithm that integrates migration of rejected tasks with resource reclaiming and an acceptance test of newly arrived tasks. Simulation results underline the effectiveness of the presented approach.","PeriodicalId":204411,"journal":{"name":"Sixth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing, 2003.","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130397375","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}
