One is a delay-constrained multicast algorithm that finds a multicast tree between one source node and multiple destination nodes. The other is a dynamic multicast algorithm that allows multiple nodes to dynamically join or leave a multicast group during a session. The first algorithm, which provides multicasting and guaranteed QoS (Quality-of-Service) services at the network layer, is a distributed routing algorithm where the reduced multicast tree is computed through a single round of message exchanges between network nodes, consequently reducing the number of messages and the accompanying computation time. The distributed algorithm is shown to generate within much less time a multicast tree slightly more expensive than that by the centralized one. The second algorithm is efficient under dynamic network environment, with frequent status changes for network nodes or links and multicast group members.","PeriodicalId":224095,"journal":{"name":"Proceedings of the Fifth IEEE Computer Society Workshop on Future Trends of Distributed Computing Systems","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127233201","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}

Furthermore, DSM gives us the ease of programming and portability. Also the advantages offered by DSM include low network overhead, with no explicit operating system intervention to move data over network. With the advent of high-bandwidth networks and wide addressing, adopting DSM for distributed systems seems to be attractive. In this paper, we propose two alternative distributed system architectures which are attempts at adopting DSM for distributed object management systems. The two proposed architectures are distributed shared cache (DSC) architecture and distributed shared recoverable virtual memory (DSRVM) architecture. We address several major issues in the proposed architectures.","PeriodicalId":224095,"journal":{"name":"Proceedings of the Fifth IEEE Computer Society Workshop on Future Trends of Distributed Computing Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114790865","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 the paper we discuss the difficulties associated with extending existing services to operate on mobile networks. As case studies, the paper discusses two particular protocols: a total order protocol and a fault-tolerant remote invocation scheme.

To support such applications, it is desirable for middleware such as ODP, CORBA or OSF/DCE to run on real-time operating systems with real-time communication facilities. In this environment, the real-time trader which can perform trading service under time constraints is required to provide location. Transparency and late binding of distributed entities. In this paper, we propose a new request scheduling algorithm for a real-time trader and suggest a real-time connection management method on CMA. It will enable distributed real-time applications to run on existing middleware with real-time operating system and real-time communication support.
