Algorithms for advance bandwidth reservation in media production networks

Media production generally requires many geographically distributed actors (e.g., production houses, broadcasters, advertisers) to exchange huge amounts of raw video and audio data. Traditional distribution techniques, such as dedicated point-to-point optical links, are highly inefficient in terms of installation time and cost. To improve efficiency, shared media production networks that connect all involved actors over a large geographical area, are currently being deployed. The traffic in such networks is often predictable, as the timing and bandwidth requirements of data transfers are generally known hours or even days in advance. As such, the use of advance bandwidth reservation (AR) can greatly increase resource utilization and cost efficiency. In this paper, we propose an Integer Linear Programming formulation of the bandwidth scheduling problem, which takes into account the specific characteristics of media production networks, is presented. Two novel optimization algorithms based on this model are thoroughly evaluated and compared by means of in-depth simulation results

Business Case and Technology Analysis for 5G Low Latency Applications

A large number of new consumer and industrial applications are likely to change the classic operator's business models and provide a wide range of new markets to enter. This article analyses the most relevant 5G use cases that require ultra-low latency, from both technical and business perspectives. Low latency services pose challenging requirements to the network, and to fulfill them operators need to invest in costly changes in their network. In this sense, it is not clear whether such investments are going to be amortized with these new business models. In light of this, specific applications and requirements are described and the potential market benefits for operators are analysed. Conclusions show that operators have clear opportunities to add value and position themselves strongly with the increasing number of services to be provided by 5G.Comment: 18 pages, 5 figure

Case Study of South Koreas Digital Service Sector

학위논문(석사) -- 서울대학교대학원 : 국제대학원 국제학과(국제통상전공), 2023. 2. 김종섭.The digital transformation brought significant impacts on international trade. Access to digitalization and new technologies lowered barriers to entry in global markets, contributing to higher trade competitiveness. Digitalization has reshaped how trade is conducted by changing the nature of its transaction. Digital trade is now a salient feature in international trade, and the digital service sector shows prominent growth across the globe by fostering technological innovation and economic development. Countries with active participation in digital trade translate into having an international competitive advantage. The following paper aims to define what digital trade is and empirically analyze competitiveness in digital service sectors of 28 OECD member states from 2010 to 2020 using Balassas Revealed Comparative Advantage (RCA) index and Michael Porters diamond model to explain the surge in digital trade. To classify digital services within the commercial service sector, this paper utilizes EBPOS 2010 statistics to categorize digital trade into ICT-enabled services and other potentially ICT-enabled services. Looking at the empirical results, the paper shows a consistent RCA index in service sectors or goods commodities for certain countries while some countries go through unprecedented changes from having a comparative advantage in other service sectors to digital service sectors. Thus, this paper will analyze countries with the highest Revealed Comparative Advantage (RCA) index in the digital service sector and apply Porters diamond model to explain the reasons behind the sudden growth in digital trade.디지털 전환은 국제 무역에 상당한 영향을 미쳤다. 디지털화와 신기술에 대한 접근성은 무역 경쟁력을 높이는 데 기여하여 세계 시장에서의 진입 장벽을 낮췄다. 디지털화는 거래의 "성질"을 바꿈으로써 무역이 이루어지는 방식을 변화시켰다. 디지털 무역은 이제 국제 무역에서 두드러진 특징이며, 디지털 서비스 부문은 기술 혁신과 경제 발전을 촉진함으로써 전 세계적으로 빠른 성장을 보이고 있다. 디지털 무역에 적극적으로 참여하는 국가는 국제적인 경쟁 우위를 갖는 것으로 해석된다. 다음 논문은 디지털 무역의 급증을 설명하기 위해 Balassa의 현시비교우위지수 (RCA)와 Michael Porter의 다이아몬드 모델을 이용하여 2010년부터 2020년까지 OECD 28개 회원국의 디지털 서비스 경쟁력을 실증연구 방법론과 질적연구 방법론으로 분석하는 것을 목적으로 한다. 본 논문에서는 상용 서비스 분야 내에서 디지털 서비스를 분류하기 위해 EBPOS 2010 통계를 활용하여 디지털 서비스를 ICT 지원 서비스와 기타 잠재적인 ICT 지원 서비스로 분류한다. 실증분석 결과를 살펴보면, 본 논문은 일부 국가가 다른 서비스 분야에서 디지털 서비스 분야로 비교우위를 갖는 것에서 전례 없는 변화를 겪은 반면, 특정 국가에 대한 서비스 분야 또는 상품 분야에서 일관된 RCA 지수를 보여주고 있다. 따라서 본 논문에서는 디지털 서비스 분야에서 가장 높은 RCA 지수를 보유한 국가들 중 한국의 디지털 서비스 분야의 사례를 분석하고 포터의 다이아몬드 모델을 적용하여 디지털 무역이 급성장하는 이유를 질적연구 방법론을 이용하여 설명하고자 한다.CHAPTER I.

Is Fragmentation a Threat to the Success of the Internet of Things?

The current revolution in collaborating distributed things is seen as the first phase of IoT to develop various services. Such collaboration is threatened by the fragmentation found in the industry nowadays as it brings challenges stemming from the difficulty to integrate diverse technologies in system. Diverse networking technologies induce interoperability issues, hence, limiting the possibility of reusing the data to develop new services. Different aspects of handling data collection must be available to provide interoperability to the diverse objects interacting; however, such approaches are challenged as they bring substantial performance impairments in settings with the increasing number of collaborating devices/technologies.Comment: 16 pages, 2 figures, Internet of Things Journal (http://ieee-iotj.org

A review of Smart Contract Blockchain Based on Multi-Criteria Analysis: Challenges and Motivations

A smart contract is a digital program of transaction protocol (rules of contract) based on the consensus architecture of blockchain. Smart contracts with Blockchain are modern technologies that have gained enormous attention in scientific and practical applications. A smart contract is the central aspect of a blockchain that facilitates blockchain as a platform outside the cryptocurrency spectrum. The development of blockchain technology, with a focus on smart contracts, has advanced significantly in recent years. However research on the smart contract idea has weaknesses in the implementation sectors based on a decentralized network that shares an identical state. This paper extensively reviews smart contracts based on multi criteria analysis challenges and motivations. Therefore, implementing blockchain in multi-criteria research is required to increase the efficiency of interaction between users via supporting information exchange with high trust. Implementing blockchain in the multi-criteria analysis is necessary to increase the efficiency of interaction between users via supporting information exchange and with high confidence, detecting malfunctioning, helping users with performance issues, reaching a consensus, deploying distributed solutions and allocating plans, tasks and joint missions. The smart contract with decision-making performance, planning and execution improves the implementation based on efficiency, sustainability and management. Furthermore the uncertainty and supply chain performance lead to improved users confidence in offering new solutions in exchange for problems in smart contacts. Evaluation includes code analysis and performance while development performance can be under development.Comment: Revie

Digitising the Industry Internet of Things Connecting the Physical, Digital and VirtualWorlds

This book provides an overview of the current Internet of Things (IoT) landscape, ranging from the research, innovation and development priorities to enabling technologies in a global context. A successful deployment of IoT technologies requires integration on all layers, be it cognitive and semantic aspects, middleware components, services, edge devices/machines and infrastructures. It is intended to be a standalone book in a series that covers the Internet of Things activities of the IERC - Internet of Things European Research Cluster from research to technological innovation, validation and deployment. The book builds on the ideas put forward by the European Research Cluster and the IoT European Platform Initiative (IoT-EPI) and presents global views and state of the art results on the challenges facing the research, innovation, development and deployment of IoT in the next years. The IoT is bridging the physical world with virtual world and requires sound information processing capabilities for the "digital shadows" of these real things. The research and innovation in nanoelectronics, semiconductor, sensors/actuators, communication, analytics technologies, cyber-physical systems, software, swarm intelligent and deep learning systems are essential for the successful deployment of IoT applications. The emergence of IoT platforms with multiple functionalities enables rapid development and lower costs by offering standardised components that can be shared across multiple solutions in many industry verticals. The IoT applications will gradually move from vertical, single purpose solutions to multi-purpose and collaborative applications interacting across industry verticals, organisations and people, being one of the essential paradigms of the digital economy. Many of those applications still have to be identified and involvement of end-users including the creative sector in this innovation is crucial. The IoT applications and deployments as integrated building blocks of the new digital economy are part of the accompanying IoT policy framework to address issues of horizontal nature and common interest (i.e. privacy, end-to-end security, user acceptance, societal, ethical aspects and legal issues) for providing trusted IoT solutions in a coordinated and consolidated manner across the IoT activities and pilots. In this, context IoT ecosystems offer solutions beyond a platform and solve important technical challenges in the different verticals and across verticals. These IoT technology ecosystems are instrumental for the deployment of large pilots and can easily be connected to or build upon the core IoT solutions for different applications in order to expand the system of use and allow new and even unanticipated IoT end uses. Technical topics discussed in the book include: • Introduction• Digitising industry and IoT as key enabler in the new era of Digital Economy• IoT Strategic Research and Innovation Agenda• IoT in the digital industrial context: Digital Single Market• Integration of heterogeneous systems and bridging the virtual, digital and physical worlds• Federated IoT platforms and interoperability• Evolution from intelligent devices to connected systems of systems by adding new layers of cognitive behaviour, artificial intelligence and user interfaces.• Innovation through IoT ecosystems• Trust-based IoT end-to-end security, privacy framework• User acceptance, societal, ethical aspects and legal issues• Internet of Things Application

Information Technology Platforms: Definition and Research Directions

The concept of an information technology (IT) related platform is broad and covers phenomena ranging from the operating system Linux to the Internet. Such platforms are of increasing importance to innovation and value creation across many facets of industry and daily life. There is, however, a lack of common understanding in both research and industry about what is mean by the term platform when related to IT. This lack of consensus is detrimental to research and knowledge development. Thus, the aims of this study are to: (i) provide a sound definition of the IT-platform concept by identifying its distinguishing dimensions; and (ii) identify important current research directions for the IT-platform concept. To achieve these aims a systematic literature review was undertaken with 133 relevant articles taken from major information systems journals, conferences, and business publications. The study contributes by providing a sound base for future research into IT-platforms.Comment: Research-in-progress ISBN# 978-0-646-95337-3 Presented at the Australasian Conference on Information Systems 2015 (arXiv:1605.01032
