It is concluded that, unless the performance objectives of satellite systems significantly exceeds those derived from CCITT/ITU-T Recommendation G.826, fiber optic cables will become the preferred choice for international transmission. The following approaches to facsimile quality improvement are examined: increasing the reliability of the IDR link either by augmenting the transmission power or by using a more robust error correction coding or both; and enhancing the operation of the circuit multiplication equipment (CME) for facsimile by introducing a service-specific forward error correction (FEC) coding for facsimile.<<ETX>>","PeriodicalId":206154,"journal":{"name":"First IEEE Symposium on Global Data Networking","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126005554","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 paper describes a management model which is based on the hierarchical modelling of situations and the association of management actions to the situation descriptions. An inference engine is developed to search the hierarchy for the management strategy that is most suitable for the current situation in the network. The most important advantages of this model are the reusability of knowledge and the support for the rapid integration of management applications into the distributed environment.<<ETX>>","PeriodicalId":206154,"journal":{"name":"First IEEE Symposium on Global Data Networking","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129655749","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}

New services are required which support gigabit applications with high throughput, remote procedure calls with low service latency, conferencing with multipoint associations or interactive audio/video communications with real-time transport qualities. Providing the new required services with the existing connection-oriented or connectionless services is in most cases insufficient because of poor performance results or missing capabilities. Also, defining dedicated services for each new application class in order to achieve optimal support may lead to an unfavorably large set of service definitions and consequently to an immense number of protocols and protocol variants. Our approach presented in this paper provides a concept for a configurable transport service which mostly subsumes existing and newly required services. This new transport service is part of the TIP (Transport and Internetworking Package) project.<<ETX>>","PeriodicalId":206154,"journal":{"name":"First IEEE Symposium on Global Data Networking","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129104831","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}

Accurate characterization of the multimedia traffic is essential, in ATM networks, in order to develop a robust set of traffic descriptors. Such set is required, by the usage parameter control (UPC) algorithm, for traffic enforcement (policing). In this paper, we present a novel approach to characterize and model the multimedia traffic using neural networks (NNs). A backpropagation neural network is used to characterize and predict the statistical variations of the packet arrival process resulting from the superposition of N packetized video sources and M packetized voice sources. The accuracy of the results were verified by matching the index of dispersion for counts (IDC), the variance, and the autocorrelation of the arrival process to those of the NN output. The reported results show that the NNs can be successfully utilized to characterize the complex non-renewal process with extreme accuracy.<<ETX>>","PeriodicalId":206154,"journal":{"name":"First IEEE Symposium on Global Data Networking","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125357815","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}

All the messages are encrypted by the same public key cryptosystem and composed of three message elements. The first message element is a random number which is added to prevent the reconstruction attack. The second message element is used to identify the next third party. The third message element is passed to the next third party identified by the second one. The next third party will follow the same process as above.

This paper proposes a scheme for guaranteeing QOS in the B-ISDN/ATM framework while utilizing resources. It addresses the key open issue involved in this challenge and poses a solution different from the current approaches. The fundamental idea of the scheme is to extend the virtual path concept to include a reservation of time slots at switching nodes by each virtual path. Cells for a session are divided into two classes at the access node: those that are guaranteed transmission within the reserved time slots and those that are discardable. Through this global and active control along virtual paths. Data transfer in a network resembles writing to input ports of a personal computer with deterministic delay and zero loss. By implementing an architecture as layers, resources are utilized without sacrificing processing time on fly.<<ETX>>","PeriodicalId":206154,"journal":{"name":"First IEEE Symposium on Global Data Networking","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123099356","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}

Focusing on the \"flow enforcement\" mechanism as part of the preventive congestion control in ATM networks, the authors attempt to modify the \"exponentially weighted moving average\" (EWMA) flow enforcement technique. The 'enhanced EWMA', the authors call the EEWMA, is proposed as an alternative flow enforcement mechanism that overcomes the major disadvantage of the EWMA, thus becoming a powerful candidate for the standardization of the flow enforcement in ATM networks. The various design issues of the EEWMA are first discussed. The performances of both the EWMA and the EEWMA mechanisms are then evaluated via simulation, under similar environments. Simulation results show that the EEWMA is consistently better. No theoretical analysis is presented.<<ETX>>","PeriodicalId":206154,"journal":{"name":"First IEEE Symposium on Global Data Networking","volume":"29 13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125787554","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}
