Likewise, they may wish to increase their sending rate if there is extra bandwidth available within the network. This kind of applications is supported by an ATM layer service called the available bit rate service (ABR). Applications using the ABR service can expect the following quality of service commitments from the network: 1. The available bandwidth is fairly distributed among all active ABR connections. 2. A minimum cell rate that is agreed upon during the connection establishment phase. 3. Only a preset fraction of the sent celIs can be dropped as long as the sending behavior of the application conforms to the negotiated values.","PeriodicalId":178651,"journal":{"name":"The Fourth IEEE Workshop on High-Performance Communication Systems","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117097131","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, it is yet to address CSCW (Computer Supported Collaborative Work) ftamework. This paper addresses the problem of building a framework for CSCW and proposes a new CSCW framework based on CORBA (CFC). CFC includes session, participant, mode, directory, stream, media and resource management. A desktop conference system and DSM-CC compliant video-on-demand system were built to demonstrate the usefulness of the framework. The performance of CORBA based CSCW applications is given. The strengths and weaknesses of using a CORBA framework are also discussed.","PeriodicalId":178651,"journal":{"name":"The Fourth IEEE Workshop on High-Performance Communication Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123778794","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}

Internet environment. In this paper we outline an architecture and an implementation of a real-time continuous media adaptive application that includes the Real-time Transport Protocol (RTP) and its associated control protocol (RTCP). The application makes use of the RTCP feedback reports for Quality of Service (QoS) monitoring of the traffic load on the network. The feedback reports are utilised by the application's adaptive rate controller to alleviate the problem of network congestion. We are assessing the suitability of RTPfRTCP in this application. Results obtained from our experiments with the adaptive rate controller are described and discussed. Then, some problems and issues concerning adaptive applications are presented. Finally, we outline the next phase of our work which concerns development of management facilities.","PeriodicalId":178651,"journal":{"name":"The Fourth IEEE Workshop on High-Performance Communication Systems","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127541727","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 signal processing techniques for fax coding, data encryption, and automatic cryptographic key management based on Public Key cryptography are discussed. The proposed system architecture can exploit the latest advances in DSP microprocessor and VLSI technology to offer lower cost, reduced size, and higher performance cryptosystems. This approach was successfully adopted by Intracorn S.A. in the design and implementation of Secl-ine-Fax secure fax communications system and constitutes the continuation of work on secure voice systems.","PeriodicalId":178651,"journal":{"name":"The Fourth IEEE Workshop on High-Performance Communication Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131287920","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}
