It was the largest and most ambitious program in U.S. Army history. The FCS program began in 2003 and was canceled in 2009 due to software issues. In 2005, FCS software in development was estimated at 63.8 million lines of code. The FCS had to get its own operating system (SOSCOE) and required the development of more than 100 programming interfaces for external applications. A key failure is seen in the CORBA programming methodology. CORBA was introduced in the 1990s and was created for the portability of remote procedure call (RPC) applications within distributed systems. The Joint Tactical Radio System (JTRS) played a major liaison role in the FCS program. JTRS was supposed to replace about 30 different military systems. In this case, the JTRS devices had to act as a phone, a computer, and a network router at the same time. JTRS was supposed to become a connecting component for all 18 weapons systems (combat vehicles, manned aircraft, drones, missiles, etc.) that were combined into FCS. SDR contained more than four million lines of code. The JTRS project was launched in 1997, but military customers canceled the project as early as 2011 after it failed integration tests. The failures of the FCS and JTRS programs meant that the concept of network-centric warfare was never realized. Currently, there is a turn towards decision-oriented warfare based on artificial intelligence.","PeriodicalId":426797,"journal":{"name":"2022 Workshop on Microwave Theory and Techniques in Wireless Communications (MTTW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132118922","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}

Hai","doi":"10.1109/MTTW56973.2022.9942542","DOIUrl":"https://doi.org/10.1109/MTTW56973.2022.9942542","url":null,"abstract":"Among various aspects in optical network architectures, handling transit traffic at intermediate nodes represents a defining characteristic for classification. In this context, the transition from the first generation of optical-electrical-optical mode to the second generation of optical-bypass marked a paradigm shift in redesigning optical transport networks towards greater network efficiency. Optical-bypass operation has then become the de facto approach adopted by the majority of carriers in both metro and backbone networks. However, in optical-bypass network, the fact that in-transit lightpaths crossing a common intermediate node must be separated in either time, frequency or spatial domain to avoid adversarial interference appears to be a critical shortcoming as the interaction of such lightpaths in optical domain may result in efficient computing and/or signal processing operations for saving spectral resources. Inspired by the accelerated progresses in optical signal processing technologies and the integration of computing and communications, we introduce in this paper a new architectural paradigm for future optical networks and highlight how this new architecture has the potential to shatter the status quo. Indeed, our proposal is centered on exploiting the superposition of in-transit lightpaths at intermediate nodes to generate more spectrally efficient lightpaths and how to harness this opportunity from network design perspectives. We present two case studies featuring optical aggregation and optical XOR encoding to demonstrate the merit of optical-processing-enabled operation compared to its counterpart, optical-bypass. Preliminary results on realistic network typologies are provided, revealing that a spectral saving up to 30% could be achieved thanks to adopting optical-processing network.","PeriodicalId":426797,"journal":{"name":"2022 Workshop on Microwave Theory and Techniques in Wireless Communications (MTTW)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116563649","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}
