A method for formally specifying the structure of time-dependent documents is proposed. A time-dependent document consists of temporal information, spatial information and content information. The proposed structure can include various types of objects which can specify those three types of information. It is shown that a tree structure is suitable for representing a TDMD system. By using the proposed structure, intelligent processing such as retrieving of content information by name, by time, and by location, independent editing of content information, location editing, and time editing can be realized. To interchange a document between computers, the structure of the document is described by ASN.1. A prototype system was implemented in which a time-dependent document can be interchanged between SUN workstations.<<ETX>>","PeriodicalId":250212,"journal":{"name":"Eleventh Annual International Phoenix Conference on Computers and Communication [1992 Conference Proceedings]","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129432914","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 author introduces a declarative notation to specify the structure of a distributed repository environment. A complementary notation is offered to specify event-based sending and receiving of data objects via port links. The notation allows for detailed specification of trigger events, of data object selection of transfer destination selection, and of several options to control transfer management at runtime. The approach supports a strict decoupling of local data processing and of distributed data exchange. In addition, it makes a decentralized model of data storage possible, as opposed to the more costly model of ubiquity provided by distributed databases. The practical use of the approach is illustrated by examples.<<ETX>>","PeriodicalId":250212,"journal":{"name":"Eleventh Annual International Phoenix Conference on Computers and Communication [1992 Conference Proceedings]","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129827941","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}

Type 1 packets are of relatively short duration, need a very quick response time, and have a high arrival rate. Type 2 packets are of longer duration, do not require as fast a response time, and have a low arrival rate. Expressions are developed for both the throughput and delay performance of two channel reservation network (TCRN), two channel reservation network with a preemptive priority, (TCRN/PP), and two channel reservation network with a nonpreemptive priority (TCRN/NPP) protocols. To examine the behavior of the protocols under time-constrained conditions, the authors check the percentage of voice packets which are transmitted within a given amount of time after their generation at a transmitting station and the voice capacity, both under different operating conditions. The results show that the channel is efficiently used to minimize the average delay for the data portion and to maintain as many voice stations as possible.<<ETX>>","PeriodicalId":250212,"journal":{"name":"Eleventh Annual International Phoenix Conference on Computers and Communication [1992 Conference Proceedings]","volume":"7 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122948207","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 OSI standards for the transport layer and for file transfer (FTAM) at the application layer have been used as models for the protocol. The transport protocol is based on a selective-repeat strategy for error recovery. The advantage of this strategy is that the protocol can handle the transfer in two phases. In the first phase the whole file is transmitted as a continuous stream of packets, and the sender just collects negative acknowledgements from receivers that lost packets. After that the sender enters the retransmission phase where the NACKed packets are retransmitted. The 'clever' receivers that have not lost any packets can deliver the complete file after the first transfer phase.<<ETX>>","PeriodicalId":250212,"journal":{"name":"Eleventh Annual International Phoenix Conference on Computers and Communication [1992 Conference Proceedings]","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131657173","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}

APLICOT breaks down all of the different kinds of online application processing at NTT into six major types based on the processing types of messages and files. APLICOT then provides a set of 54 API parts for each type to standardize AP development environments. This set minimizes the total development cost of AP and these API parts. APLICOT's purpose is to standardize AP development support systems while allowing flexibility in the number of required AP programmers and in their tasks.<<ETX>>","PeriodicalId":250212,"journal":{"name":"Eleventh Annual International Phoenix Conference on Computers and Communication [1992 Conference Proceedings]","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125613110","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}
