Judging traffic differentiation as network neutrality violation according to internet regulation

Network Neutrality (NN) is a principle that establishes that traffic generated by Internet applications should be treated equally and it should not be affected by arbitrary interfer- ence, degradation, or interruption. Despite this common sense, NN has multiple defi- nitions spread across the academic literature, which differ primarily on what constitutes the proper equality level to consider the network as neutral. NN definitions may also be included in regulations that control activities on the Internet. However, the regulations are set by regulators whose acts are valid within a geographical area, named jurisdic- tion. Thus, both the academia and regulations provide multiple and heterogeneous NN definitions. In this thesis, the regulations are used as guidelines to detect NN violations, which are, by this approach, the adoption of traffic management practices prohibited by regulators. Thereafter, the solutions can provide helpful information for users to support claims against illegal traffic management practices. However, state-of-the-art solutions adopt strict academic definitions (e.g., all traffic must be treated equally) or adopt the regulatory definitions from one jurisdiction, which is not realistic or does not consider that multiple jurisdictions may be traversed in an end-to-end network path, respectively An impact analysis showed that, under certain circumstances, from 39% to 48% of the detected Traffic Differentiations (TDs) are not NN violations when the regulations are considered, exposing that the regulatory aspect must not be ignored. In this thesis, a Reg- ulation Assessment step is proposed to be performed after the TD detection. This step shall consider all NN definitions that may be found in an end-to-end network path and point out NN violation when they are violated. A service is proposed to perform this step for TD detection solutions, given the unfeasibility of every solution implementing the re- quired functionalities. A Proof-of-Concept (PoC) prototype was developed based on the requirements identified along with the impact analysis, which was evaluated using infor- mation about TDs detected by a state-of-the-art solution. The verdicts were inconclusive (the TD is an NN violation or not) for a quarter of the scenarios due to lack of information about the traversed network paths and the occurrence zones (where in the network path, the TD is suspected of being deployed). However, the literature already has proposals of approaches to obtain such information. These results should encourage TD detection solution proponents to collect this data and submit them for the Regulation Assessment.Neutralidade da rede (NR) é um princípio que estabelece que o tráfego de aplicações e serviços seja tratado igualitariamente e não deve ser afetado por interferência, degradação, ou interrupção arbitrária. Apesar deste senso comum, NR tem múltiplas definições na literatura acadêmica, que diferem principalmente no que constitui o nível de igualdade adequado para considerar a rede como neutra. As definições de NR também podem ser incluídas nas regulações que controlam as atividades na Internet. No entanto, tais regu- lações são definidas por reguladores cujos atos são válidos apenas dentro de uma área geográfica denominada jurisdição. Assim, tanto a academia quanto a regulação forne- cem definições múltiplas e heterogêneas de NR. Nesta tese, a regulação é utilizada como guia para detecção de violação da NR, que nesta abordagem, é a adoção de práticas de gerenciamento de tráfego proibidas pelos reguladores. No entanto, as soluções adotam definições estritas da academia (por exemplo, todo o tráfego deve ser tratado igualmente) ou adotam as definições regulatórias de uma jurisdição, o que pode não ser realista ou pode não considerar que várias jurisdições podem ser atravessadas em um caminho de rede, respectivamente. Nesta tese, é proposta uma etapa de Avaliação da Regulação após a detecção da Diferenciação de Tráfego (DT), que deve considerar todas as definições de NR que podem ser encontradas em um caminho de rede e sinalizar violações da NR quando elas forem violadas. Uma análise de impacto mostrou que, em determinadas cir- cunstâncias, de 39% a 48% das DTs detectadas não são violações quando a regulação é considerada. É proposto um serviço para realizar a etapa de Avaliação de Regulação, visto que seria inviável que todas as soluções tivessem que implementar tal etapa. Um protótipo foi desenvolvido e avaliado usando informações sobre DTs detectadas por uma solução do estado-da-arte. Os veredictos foram inconclusivos (a DT é uma violação ou não) para 75% dos cenários devido à falta de informações sobre os caminhos de rede percorridos e sobre onde a DT é suspeita de ser implantada. No entanto, existem propostas para realizar a coleta dessas informações e espera-se que os proponentes de soluções de detecção de DT passem a coletá-las e submetê-las para o serviço de Avaliação de Regulação

Offshore Wind Data Integration

Doktorgradsavhandling i informasjons- og kommunikasjonsteknologi, Universitetet i Agder, Grimstad, 2014Using renewable energy to meet the future electricity consumption and to reduce environmental impact is a significant target of many countries around the world. Wind power is one of the most promising renewable energy technologies. In particular, the development of offshore wind power is increasing rapidly due to large areas of wind resources. However, offshore wind is encountering big challenges such as effective use of wind power plants, reduced cost of installation as well as operation and maintenance (O&M). Improved O&M is likely to reduce the hazard exposure of the employees, increase income, and support offshore activities more efficiently. In order to optimize the O&M, the importance of data exchange and knowledge sharing within the offshore wind industry must be realized. With more data available and accessible, it is possible to make better decisions, and thereby improve the recovery rates and reduce the operational costs. This dissertation proposes a holistic way of improving remote operations for offshore wind farms by using data integration. Particularly, semantics and integration aspects of data integration are investigated. The research looks at both theoretical foundations and practical implementations. As the outcome of the research, a framework for data integration of offshore wind farms has been developed. The framework consists of three main components: the semantic model, the data source handling, and the information provisioning. In particular, an offshore wind ontology has been proposed to explore the semantics of wind data and enable knowledge sharing and data exchange. The ontology is aligned with semantic sensor network ontology to support management of metadata in smart grids. That is to say, the ontology-based approach has been proven to be useful in managing data and metadata in the offshore wind and in smart grids. A quality-based approach is proposed to manage, select, and provide the most suitable data source for users based upon their quality requirements and an approach to formally describing derived data in ontologies is investigated

The Deep Underground Neutrino Experiment (DUNE) will be a world-class neutrino observatory and nucleon decay detector designed to answer fundamental questions about the nature of elemen tary particles and their role in the universe. The international DUNE experiment, hosted by the U.S. Department of Energy’s Fermilab, will consist of a far detector to be located about 1.5 km underground at the Sanford Underground Research Facility (SURF) in South Dakota, USA, at a distance of 1300 km from Fermilab, and a near detector to be located at Fermilab in Illinois. The far detector will be a very large, modular liquid argon time-projection chamber (LArTPC) with a 40 kt (40 Gg) fiducial mass. This LAr technology will make it possible to reconstruct neutrino interactions with image-like precision and unprecedented resolution

Event Generators for High-Energy Physics Experiments

We provide an overview of the status of Monte-Carlo event generators for high-energy particle physics. Guided by the experimental needs and requirements, we highlight areas of active development, and opportunities for future improvements. Particular emphasis is given to physics models and algorithms that are employed across a variety of experiments. These common themes in event generator development lead to a more comprehensive understanding of physics at the highest energies and intensities, and allow models to be tested against a wealth of data that have been accumulated over the past decades. A cohesive approach to event generator development will allow these models to be further improved and systematic uncertainties to be reduced, directly contributing to future experimental success. Event generators are part of a much larger ecosystem of computational tools. They typically involve a number of unknown model parameters that must be tuned to experimental data, while maintaining the integrity of the underlying physics models. Making both these data, and the analyses with which they have been obtained accessible to future users is an essential aspect of open science and data preservation. It ensures the consistency of physics models across a variety of experiments
