SDS employs the synchronization quality of service parameters to guarantee the simultaneous delivery for the different types of the application data streams. Without any global clock, SDS performs the synchronization recovery to preserve a high quality multimedia display. Different segment delivery schemes are addressed. The performance modeling and analysis of the SDS am also conducted. Relevant results such as the impact of the segment size, the size of the recovery buffer needed at the receiver, etc., are obtained.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122669642","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 control of the switch is completely distributed; thus, it scales well to large sizes. The switch employs a combined external input-output buffering strategy, and operates in such a way so that output buffer overflows never happen. An analytical model, that takes into account this backpressure mechanism, is developed for arbitrary switch size, input buffer size, output buffer size, and expansion factor. Computer simulations are used to validate the analysis and to examine the performance under bursty traffic. It is shown that reasonable expansion factors are required to achieve high performance for large switch sizes. It is also shown that memory savings are achieved by avoiding output buffer overflows. Finally, a distinctive feature of the proposed architecture is that internal node buffering can be used without disturbing the cell sequence integrity.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123871587","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}

A CRC code is included in the scheme to trigger retransmission requests. Multiple received packets are combined on a bit by bit basis to form a single, more reliable packet. The error correcting decoder operates on the combined packet, as opposed to the most recently received individual packet (e.g. as in a type-I hybrid ARQ protocol), substantially increasing the probability of acceptance with each additional transmission. We show through analysis and simulation results that the proposed technique allows a significant increase in the CDMA system capacity, throughput and reliability.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130265223","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}

Analysis of the hop distance properties for this network when its links are bidirectional is straightforward. However, the analysis of this network with unidirectional links is more complex, and the literature only provides the mean hop distance for the unidirectional version when the nodal degree is two. The authors provide a closed-form, analytical formula for the average hop distance in a three-dimensional torus network with unidirectional links, and hypothesize an approximate result for higher dimensions. The importance of this work stems from the fact that the torus is a useful candidate for the construction of an optical network with a multihop virtual topology based on wavelength division multiplexing (WDM). So far, it has not been possible to conduct fair comparisons between the torus and other multihop topologies with nodal degree greater than two, but the present work will now enable such comparisons.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129469454","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}

Moreover we analyze the error performance of trellis-coded OMPPM with the small overlap index N=2 in optical direct-detection channel to achieve significant coding gains over uncoded MPPM with the same pulsewidth. First we analyze the block error probability of OMPPM in the background noise case by using the distance defined as the number of nonoverlapping pulsed chips between symbols. Second by using this distance, we partition the OMPPM signals and apply the four-state and the eight-state codes described by Ungerboeck (1982,1987) to OMPPM. It is shown that TCM is effective for OMPPM in optical direct-detection channel. The four-state and the eight-state trellis coded OMPPM can achieve gains of 1.56 dB and 3.37 dB over uncoded MPPM at the error probability of 10/sup -6/ in background noise case, respectively.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128701753","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}
