Architectural Considerations for a Self-Configuring Routing Scheme for Spontaneous Networks

Decoupling the permanent identifier of a node from the node's topology-dependent address is a promising approach toward completely scalable self-organizing networks. A group of proposals that have adopted such an approach use the same structure to: address nodes, perform routing, and implement location service. In this way, the consistency of the routing protocol relies on the coherent sharing of the addressing space among all nodes in the network. Such proposals use a logical tree-like structure where routes in this space correspond to routes in the physical level. The advantage of tree-like spaces is that it allows for simple address assignment and management. Nevertheless, it has low route selection flexibility, which results in low routing performance and poor resilience to failures. In this paper, we propose to increase the number of paths using incomplete hypercubes. The design of more complex structures, like multi-dimensional Cartesian spaces, improves the resilience and routing performance due to the flexibility in route selection. We present a framework for using hypercubes to implement indirect routing. This framework allows to give a solution adapted to the dynamics of the network, providing a proactive and reactive routing protocols, our major contributions. We show that, contrary to traditional approaches, our proposal supports more dynamic networks and is more robust to node failures

A contribuição das tecnologias da informação e comunicação na formação continuada de professores: um estudo de caso em um curso de especialização no ensino de Química

Esta pesquisa teve como objetivo avaliar a contribuição da disciplina de Informática Aplicada ao Ensino de Química, na formação de professores de química, realizada durante um semestre, no curso de especialização no ensino de química na Faculdade de Formação de Professores da Mata Sul,em Pernambuco-Brasil. Inicialmente, os professores discutiram sobre algumas teorias voltadas a utilização das TIC na educação, posteriormente manusearam algumas ferramentas das TIC, identificando as possibilidades de seus usos em sala de aula. Ao final da disciplina responderam ao questionário de avaliação proposto. Os resultados reforçam a percepção de que a incorporação de disciplinas em cursos de formação de professores, voltadas para a capacitação no uso das TIC em sala de aula, pode contribuir sobremaneira para um processo de ensino e aprendizagem mais atrativo, amplo e flexível

Resource management for software defined data centers for heterogeneous infrastructures

Software Defined Data Center (SDDC) provides more resource management flexibility since everything is defined as a software, including the network as Software Defined Network (SDN).Typically, cloud providers overlook the network, which is configured in static way. SDN can help to meet applications goals with dynamic network configuration and provide best-efforts for QoS. Additionally, SDDC might benefit by instead of be composed by heavy Virtual Machines, use light-weight OS Containers. Despite the advantages of SDDC and OS Containers, it brings more complexity for resource provisioning. The goal of this project is to optimize the management of container based workloads deployed on Software defined Data Centers enabled with heterogeneous network fabrics through the use of network-aware placement algorithms that are driven by performance models
