To illustrate the benefit of the described modeling approach a DSPN for CSMA/CD protocols with deterministic collision resolution is presented.<<ETX>>","PeriodicalId":186762,"journal":{"name":"Proceedings of the Third Workshop on Future Trends of Distributed Computing Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127630241","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}

Generally speaking, a distributed multimedia application is constructed of four layers: the interactive layer, the data composition layer, the network transport layer and the database management system (DBMS) layer. Although these layers are the well-known reference architectures, the connections (multimedia modeling, module operations, and module communications) between them still need to be solved. To allow users easily, flexibly, and dynamically to create, query, and present multimedia documents, the authors propose five modules as an integration solution; they are, interactive user interface module, multimedia object manipulation module, object dynamically mapping module, network transport control module, and physical object file manipulation module. These modules are the essences of the behaviorally object-oriented distributed multimedia environment. Based on these modules, the multimedia object modeling, the query processing and the presentation schema are elaborated.<<ETX>>","PeriodicalId":186762,"journal":{"name":"Proceedings of the Third Workshop on Future Trends of Distributed Computing Systems","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128542137","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 operation is based on a continuous stream of slots circulating around the ring. The delay model is represented. Assuming that a slot is reserved with a preassumed probability, an expression for the z-transform of the number waiting in the queue is derived by using the embedded technique. From this the expression for the average access delay is obtained. The approximation of the probability is then found and the average delay can be solved. The incoming traffic is assumed to be Poisson. Numerical results are discussed.<<ETX>>","PeriodicalId":186762,"journal":{"name":"Proceedings of the Third Workshop on Future Trends of Distributed Computing Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122103206","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}

It discusses an X-based system model for tools necessary in a teleconferencing system, then analyzes the concurrency controls and communication mechanisms among these tools. A prototype for text-based conference called CTUTC for chairperson-members is presented since X provides dynamic-window configuration.

Obviously, there exists an alternative to the isolation of computations in distributed real-time systems which allows more concurrency between computations.<<ETX>>","PeriodicalId":186762,"journal":{"name":"Proceedings of the Third Workshop on Future Trends of Distributed Computing Systems","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129941905","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 authors investigate the NP-hard scheduling problem which consists in maximizing the sum of these awards. First on a theoretical point of view, they define an optimal decomposition : the set of the tasks to be scheduled is divided into a ranked collection of subsets so that an optimal scheduling has to respect the ranks of subsets. They also introduce two classes of polynomial scheduling algorithms which provide sequences respecting this optimal decomposition. On a practical point of view, simulation results show that these algorithms yield optimal or nearly optimal sequences in many cases.<<ETX>>","PeriodicalId":186762,"journal":{"name":"Proceedings of the Third Workshop on Future Trends of Distributed Computing Systems","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116957324","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}
