Managing communications resources (that are diverse, heterogeneous, and produced by a wide range of vendors) via current network management solutions imposes major obstacles. Network management systems (NMS), that are currently available in the market, utilize standards-based as well as proprietary network management systems. Vendors recognize the need for \"Open\" NMS products and frequently announce new products (based on the international standards (IS and draft IS, DIS) and frameworks). This paper summarizes the challenges faced by the network manager who needs to manage today's networks and addresses the difficulties associated with implementing standards-based network management software in existing systems. This paper also identifies emerging network standards/profiles and their migration strategy. The author proposes a standard-based integrated NMS (INMS) architecture, that is loosely coupled, flexible, and easily expandable. Furthermore, this architecture will provide a stable yet flexible framework upon which an interoperable communications and network management system can be built. This proposed INMS architecture will conform to existing standards and emerging international standards (Simple Network Management Protocol, (SNMP), OSI Management Standards, Government Network Management Profile (GNMP), OSI/NM Forum standards, draft DoD-MIL-STD-38000, and OMNIPoints).<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"35 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":"125679888","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}

Successful results have been reported by using WDM (wavelength division multiplexing) in two types of optical network architectures: single-hop and multihop. It has been observed that, while neither of these schemes can adequately satisfy all requirements, yet single-hop and multihop networks have positive and negative properties that tend to complement and compensate each other. The authors exploit this situation by proposing a hybrid architecture HONET (hybrid optical network) which combines the concepts of both schemes, retaining their advantages and avoiding their limitations. HONET uses a multihop network for packet service and a single-hop network for circuit-switched service. The authors show that even the simplest HONET implementation requiring only two transmitter-receiver pairs can provide better performance than a classic single-hop network.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"21 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":"115452630","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 synchronizer uses a block window accumulator (BWA) as averaging filter and postprocessing to eliminate equivocation. Approximate expressions for the cycle slip probability, valid for sufficiently large E/sub s//N/sub o/, are derived for both wideband and narrowband postprocessing. Two methods to (numerically) evaluate these expressions are presented and are verified by Monte Carlo simulations of the cycle slips for the case of QPSK. The hybrid method combines simulation and theoretical results and is very accurate. The Gaussian approximation yields accurate results only for the case of narrowband postprocessing and moderate and large values of the BWA length. The computational requirements of the Gaussian approximation are considerably less than for the hybrid method, because the former requires no simulation; in turn, the hybrid method is computationally more efficient than straightforward Monte Carlo simulations of the cycle slips. It is found that the synchronizer nonlinearities yielding the lowest linearized phase error variance also yield the lowest cycle slipping probability, for both wideband and narrowband postprocessing.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"15 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":"114545959","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}
