IEEE Software Defined Network Initiative

This paper outlines a proposal for setting up an IEEE initiative on software defined networks (SDNs) to facilitate professional and academic exchange of SDN-related ideas, research, and development. The proposal is a result of an intensive effort of a team consisting of the authors. After a comprehensive gap analysis, gaps and key opportunities were identified. Finally, a specific set of components along with schedule and financial consideration were proposed in the areas of publications, conferences, standards, education, certification, and publicity

Fundamentals of Public Safety Networks and Critical Communications Systems

Fundamentals of Public Safety Networks and Critical Communications Systems fills a gap in the literature by providing a book that reviews a comprehensive set of technologies, from most popular to the most advanced communications technologies that can be applied to public safety networks and mission-critical communications systems. The book explores the technical and economic feasibility, design, application, and sustainable operation management of these vital networks and systems. Written by a noted expert in the field, the book provides extensive coverage of systems, services, end-user devices, and applications of public-safety services and technologies. The author explores the potential for advanced public safety systems, and this comprehensive text covers all aspects of the public safety and critical communications network field

Análise dos Efeitos do Covid-19 nas Decisões de Compra de Produtos de Viagens e Turismo

This study aims to determine the differences between behaviors of potential tourists by examining how the crisis perception of COVID-19 impacts tourism demand and what kind of attitudinal dimensions potential tourists bring to the fore in their travel requests. Data were collected from 685 local tourists living in Turkey. Explanatory Factor Analysis was performed, followed by a t-test and one-way ANOVA, to determine the differences between demographic features. In the face of the pandemic, the potential tourist will tend to isolate, avoid, and turn to alternative forms of tourism. In addition, the approach to traditional travel and accommodation activities is changing and has been altogether thrown into question. The differentiation of tourism preferences according to the demographic characteristics of participants reveals that the effects of the pandemic differ depending on personal characteristics. The effect of external environmental conditions on consumer behavior and demand in tourism is a topic studied in the literature. There are also studies on the impact of regional epidemics on tourism, such as SARS, Ebola, among others. However, empirical studies on the impact of a global pandemic such as the Covid-19 on consumer behavior and demand in tourism are limited. This study which determine the effect of Covid-19 on tourism demand and consumer behavior, will contribute to the literature. The results of this study can be a guide for tourism businesses in other countries. It can be a source for academically similar studies in terms of method and application.Este estudio tiene como objetivo determinar las diferencias entre los comportamientos de los turistas potenciales al examinar cómo la percepción de crisis del COVID-19 impacta la demanda turística y qué tipo de dimensiones de actitud los turistas potenciales ponen en primer plano en sus solicitudes de viaje. Se recopilaron datos de 685 turistas locales que viven en Turquía. Se realizó un análisis factorial explicativo, seguido de una prueba t y ANOVA de una vía, para determinar las diferencias entre las características demográficas. Ante la pandemia, el turista potencial tenderá a aislarse, evitar y recurrir a formas alternativas de turismo. Además, el enfoque de las actividades tradicionales de viaje y alojamiento está cambiando y se ha cuestionado por completo. La diferenciación de las preferencias turísticas según las características demográficas de los participantes revela que los efectos de la pandemia difieren según las características personales. El efecto de las condiciones ambientales externas sobre el comportamiento del consumidor y la demanda en el turismo es un tema estudiado en la literatura. También existen estudios sobre el impacto de las epidemias regionales en el turismo, como el SARS, el Ébola, entre otras. Sin embargo, los estudios empíricos sobre el impacto de una pandemia global como el Covid-19 en el comportamiento del consumidor y la demanda en el turismo son limitados. Este estudio, que determina el efecto de Covid-19 sobre la demanda turística y el comportamiento del consumidor, contribuirá a la literatura. Los resultados de este estudio pueden ser una guía para las empresas turísticas de otros países. Puede ser una fuente de estudios académicamente similares en términos de método y aplicación.Este estudo tem como objetivo determinar as diferenças entre os comportamentos dos turistas potenciais examinando como a percepção da crise do COVID-19 impacta a demanda turística e que tipo de dimensões atitudinais os turistas potenciais trazem à tona em suas solicitações de viagens.

Context-aware service composition and delivery in NGSONs over SDN

NGSON is an IEEE sponsored effort to standardize an open service ecosystem where different stakeholders may cooperate to satisfy users' ever changing requirements by composing and delivering services dynamically across different service providers and network operators' domains. A main distinguishing feature of NGSON is context awareness, that is, the capability of collecting, processing, and using context information to drive the interactions of the NGSON overlay nodes with service and network operators' infrastructures for guaranteeing an optimal user experience. Recent advances in network control and management technologies, such as SDN, NFV, and service-oriented networking paradigms, are expected to make the network effectively able to cope with application service requirements in a more flexible, timely, and agile manner. In this article we discuss how NGSON, which already incorporates several aspects of virtualization, could take advantage of network virtualization mechanisms and programmable traffic steering capabilities to enhance and effectively support context-aware service composition along with adaptive service delivery. We propose an architectural model for NGSON that leverages these novel network service control capabilities and illustrate through a use case how this model could effectively be put into operation

Proceedings of the 17th International Conference on Network and Service Management

International audienceThis document represents the proceedings of the 17th International Conference on Network and Service Management that was held on-line on October 25-29, 2021, under the theme "Smart Management for Future Networks and Services".CNSM 2021 was dedicated to a number of topics in the area of Network Operations and management, from Artificial Intelligence techniques to Protocols, embedding performance and security issues.The proceedings comprises 92 papers, including main conference and workshop contributions, as well as demo papers

In 2013, the IEEE Future Directions Committee (FDC) formed an SDN work group to explore the amount of interest in forming an IEEE Software-Defined Network (SDN) Community. To this end, a Workshop on “SDN for Future Networks and Services” (SDN4FNS’13) was organized in Trento, Italy (Nov. 11th-13th 2013). Following the results of the workshop, in this paper, we have further analyzed scenarios, prior-art, state of standardization, and further discussed the main technical challenges and socio-economic aspects of SDN and virtualization in future networks and services. A number of research and development directions have been identified in this white paper, along with a comprehensive analysis of the technical feasibility and business availability of those fundamental technologies. A radical industry transition towards the “economy of information through softwarization” is expected in the near future.
