About

A little about me

I am a highly qualified professional, with academic and professional experience. In 2012, I started working as operational support in hardware and software for the state government of Ceará.

In 2017, finished a Degree in Computer Networks. In 2019, finished a specialization in Computer Networks with Emphasis on Security. And in 2020 concludes another Specialization in Higher Education Teaching.

Worked as a Teacher in the computer Computer Technician in 2019.

    • Desenvolvimento de Um Aplicativo para o Auxílio em Trabalhos Acadêmicos Desde os primórdios das civilizações a comunicação tem sido um fator fundamental para o desenvolvimento da sociedade. Entretanto, a escrita foi a melhor forma de comunicação acontecer de fato. Assim, a escrita científica surge nesse contexto como uma forma de registrar o conhecimento produzido. Apesar dos anos terem passado ainda hoje percebemos o quanto os alunos de graduação e ensino médio sentem dificuldade em escreverem um texto técnico. Diante disto, este artigo tem como finalidade apresentar o desenvolvimento de um aplicativo para auxiliar a produção de artigos científicos baseado nas normas da Associação Brasileira de Normas Técnicas (ABNT). Será mostrado as etapas para o desenvolvimento do aplicativo utilizando a plataforma Sketchware.

    The Internet has led to the creation of a networked digital society where almost everything is connected and accessible from anywhere. However, despite their widespread adoption, traditional IP networks are complex and very difficult to manage. It is difficult to configure the network according to the defined policies and reconfigure it to respond to failures. The Software Defined Network (SDN) paradigm is one of the topics related to computer networks much discussed at national and international events in recent years. This interest is due to the various possibilities of applying the paradigm, which presents itself as a potential way of implementing what is known as the Internet of the Future. Moreover, SDN is an emerging model that promises to change this state of business, separating the logical control network of the underlying routers and switches, promoting centralized network control and introducing the ability to program the network. This paper presents an analysis on the application of the Ryu controller, with the purpose of demonstrating the possibilities of the test combination in a simulated SDN environment. To perform the tests, two scenarios were created with Mininet and injected a network traffic. Through experiments, it was possible to see that Ryu controlled the environments as expected and that the complexity of the infrastructure did not cause large differences in data transfer delays.
