“…To model such behavior, the experiments carried out in [15], which consider 30-minute intervals in which a certain amount of videos are played, are taken into account. The analyses show that pauses take place only in 4.3% of the playbacks.…”

“…Starting from the experiments performed in [15], the PDF that describes the length of the forward, backward, and the time between playbacks is a Weibull with parameters for each characteristic α = 0.16827 and β = 0.45321, α = 0.09058 and β = 0.47459, and α = 0.16687 and β = 0.51107 respectively. By observing the number of videos, it was estimated that the number of reproductions in 30 minutes can be modeled with a Zipf distribution with a θ 1 = 1.77 parameter.…”

The video streaming service, besides offering interactivity by users' actions through pauses, backwards, and forwards, is the highest generator of traffic on data networks. Hence, it is necessary to characterize this behavior for network dimensioning. This article presents the conceptual models of the service and a lexical analyzer whose function is the automatic extraction of the different frames of traffic streams and identification of interactivity processes. Through the lexical analyzer, the information from each of the components of the service such as the I, P, and B frames is extracted; and so is the audio component. This means that the lexical analyzer provides granularity to the characterization process. Thus, it is expected that the lexical tool allows studying the behavior of traffic based on distribution functions obtained in situ, not relying on assumptions or studies from other researchers.

RESUMOAs necessidades da sociedade digital, como conectividade e acessibilidade, são alteradas de acordo com o tempo e o espaço. Logo, a dinâmica espaço-temporal da demanda por internet transforma o planejamento de investimentos em infraestrutura de telecomunicações em grande desafio. Antever as necessidades de uma sociedade digital em um futuro próximo é uma tarefa complexa, pois o desempenho do mercado é repleto de inovações e incertezas. Então, como convergir a oferta e a demanda das necessidades da sociedade digital com as cidades do futuro? Este trabalho apresenta pesquisa experimental em que uma metodologia é desenvolvida. Para isso, busca compreender os fenômenos que constituem o comportamento da demanda por internet e avaliar os efeitos espaço-temporais em sua dinâmica. Os resultados mostram que os efeitos ao longo do tempo têm impactos distintos sobre a demanda por internet em cada localidade. Tais observações mostram, sobretudo, que a demanda por internet é uma função dependente do espaço-tempo, capaz de influenciar decisões de investimento em infraestrutura de telecomunicações, maximizando o lucro e gerando externalidades positivas, como, por exemplo, na universalização do acesso à internet, a difusão da sociedade digital e a edificação das cidades do futuro.Palavras-chave: sociedade digital; conectividade; mercado de incertezas; ambiente de inovações. ABSTRACTThe needs of the digital society, such as connectivity and accessibility, are altered according to the time and space. These space-time demand dynamics turn the telecommunications infrastructure investment planning into a major challenge. Thus, predicting the needs of a digital society in the near future is a complex task, as the market performance is fraught innovations with uncertainties. So, how does one converge the supply and demand needs, cited in an environment that is constantly innovating, such as the future cities? Understanding the supply and demand of internet market behavior should include both expectations and the development of a long-term solution. This paper presents an experimental research where a methodology is developed. For this, it seeks to understand the phenomena that constitutes to the internet demand behavior and to evaluate the space-time effects on its dynamics. The proposed method indicates that temporal effects in the internet impacts demand differently as the analyzed city is changed. The results show that space-time may have an influence on telecommunications infrastructure investment decisions. Thus, the investment decision-making process would maximize profit when space-time analyses are considered. The contribution to telecommunications investment planning methods, will involve the digital society universalization in future cities.
