plataforma cloud computing como infraestructura tecnológica para laboratorios virtuales, remotos y adaptativos -Cloud computing as technologic infrastructure for virtual, remote and adaptive labs

Abstract

Actualmente las instituciones de educación superior desarrollan su docencia apoyada en los campus virtuales, en modalidad tanto presencial como semipresencial. De igual manera, la internacionalización de la enseñanza abre nuevos desafíos como: la creación de redes de investigación, espacios de trabajos compartidos, laboratorios virtuales y remotos, entre otros, apostando por sistemas de producción, publicación y distribución de contenidos educativos digitales que permitan compartir el conocimiento y el material educativo. La presente propuesta pretende potencializar el desarrollo de ecosistemas de experimentación académica, abiertos, reusables e interoperables, a través del diseño de marco de trabajo e integración tecnológica orientado a la implementación de laboratorios virtuales y teleoperados, basado en el estándar IMS Learning Tools Interoperability® (LTI®). Para lograrlo se partió de del reconocimiento del contexto para luego caracterizar el conjunto de métodos y tecnologías aplicables al desarrollo de laboratorios virtuales y teleoperados, identificar las alcances procedimentales y criterios técnicos para su desarrollo que permite ofrecer servicios informáticos en entornos académicos a través de internet, el control de los recursos, procesos e información, acceso infraestructuras de red con otros usuarios para la puesta en marcha de nuevos servicios, sin altos costos o inversión para su implementación, permitiendo una alta escalabilidad y flexibilidad en la modificación del dimensionamiento del servicio, la investigación académica y científica apoyado en estándares, arquitecturas, tecnologías, herramientas y aplicaciones abiertas y de propósito general.Cloud computing as technologic infrastructure for virtual, remote and adaptive labsABSTRACT Nowadays, institutions of higher education are developing teaching process leaning on virtual campus, in classroom and blended learning; as well as the internationalization of teaching creates new challenges, such as: creating research networks, shared workspaces, virtual and remote labs, among others; betting on production, publication and distribution systems of educative digital contents that allow sharing knowledge and educational material. This proposal pretends to potentiate the development of open, reusable and interoperable academic experimentation ecosystems, through the design of a framework and the technological integration oriented to the implementation of virtual and tele operated labs, based on IMS Learning Tools Interoperability ® (LTI®) standard. This coupled with the characterization of a set of methods and technologies applicable to the development of virtual and tele operated labs, identifying its scope and technical criteria, in order to offer informatics services in academic environments through the Internet and allowing a high scalability and flexibility in modifying the sizing of the service, academic and scientific research, supported on open standards, architectures, technologies, tools and apps.Cloud computing infra-estrutura para as technologic virtual, remoto e adaptativa labsRESUMO Hoje em dia, as instituições de ensino superior estão a desenvolver processo de ensino apoiado em campus virtual, em sala de aula e blended learning; bem como a internacionalização do ensino cria novos desafios, tais como: a criação de redes de investigação, espaços de trabalho compartilhados, laboratórios virtuais e remotos, entre outros; apostando em sistemas de produção, publicação e distribuição de conteúdos digitais educativos que permitem a partilha de conhecimentos e material educativo. Esta proposta pretende potenciar o desenvolvimento de ecossistemas experimentação acadêmicos abertos, reutilizáveis e interoperáveis, através da concepção de um quadro ea integração tecnológica orientada para a implementação de laboratórios virtuais operados e tele, com base em IMS Learning Tools Interoperability ® (LTI®) padrão . Isso, combinado com a caracterização de um conjunto de métodos e tecnologias aplicáveis ao desenvolvimento de laboratórios operados virtuais e tele, identificando o seu âmbito e critérios técnicos, a fim de oferecer serviços de informática em ambientes acadêmicos através da Internet e que permite uma alta escalabilidade e flexibilidade na modificar o dimensionamento do serviço, pesquisa acadêmica e científica, apoiada em padrões abertos, arquiteturas, tecnologias, ferramentas e aplicativos.

A software pilot application to calculate the parameters involved in subsidiaries interconnection based on FSO technology

“…In developed countries, contrary to the radio and microwave systems, to apply FSO is not usually necessary to get a spectrum license or frequency coordination with other users, because interference from one system to another is not an issue to be considered, and the laser signal transmitted point-to-point is extremely difficult to intercept, therefore, it is highly secure [2]. Data transfer rates are comparable with those of the fiber-optic; data can be transmitted with minimal error rates, while the thin laser beam assures the localization of multiple transceivers without mutual interference at any point [1].…”

Ecosystem for the deployment and management of virtual laboratories based on the standard IMS LTI

“…It contains the plug-in WebLab Deusto, Deusto, Phyton (Virtual env), MySql, Debian; the third one, Labmanager, constituted by Phyton (Virtual env), MySql, Debian; and the fourth one, LMS Sakai, which consists of Sakai 10.2, Apache Tomcat, MySql Server, Debian. Gateway4labs laboratory manager implementation: Gateway4labs is aimed at the integration of multiple laboratories in different learning environments such as: LMS, CMS content management systems or Personal Learning Environments (PLE)[27], for this it refers on a laboratory manager responsible for manage access from the LMS to the remote laboratory manager RLMS.…”
