  1. An effective algorithm for obtaining the set of all minimal cost pairs of disjoint paths with dual arc costs

    Gomes, Teresa; Craveirinha, José; Jorge, Luísa
    In today’s telecommunications networks it is necessary, for reliability reasons, to use protection schemes involving the calculation of two (or more) disjoint paths for each node-to-node connection, especially when large amounts of traffic have to be routed in the network. This concern is particularly relevant in optical networks, namely WDM (Wavelength Division Multiplexing) networks due to the very high rates supported by lightpaths, and in the Internet using MPLS (Multiprotocol Label Switching). In this context the problem of obtaining optimal (arc or node) disjoint paths, for increasing network reliability while minimising bandwidth consumption, is extremely important. The problem of finding k disjoint paths...

  2. Multi-scheme recovery in MPLS networks: preliminary results for a multischeme approach

    Jorge, Luísa; Gomes, Teresa
    MultiProtocol Label Switching (MPLS) networks have been proposed as a solution to offer reliable, efficient and differentiated telecommunication services. Nowadays several applications require high quality service and cannot recover from traffic loss using retransmissions. Routing protocols can be robust and survivable but take a long time to recover from faults, which will not be acceptable for many applications. Therefore several schemes and frameworks for MPLS recovery have been proposed to handle failures quickly [3]. The authors proposed [2] a multi-scheme recovery approach, which intends to increase overall network resilience, while using network resources efficiently by taking into account resilience requirements of...

  3. Graphical simulation of numerical algorithms : an approach based on code instrumentation and Java technologies

    Balsa, Carlos; Alves, Luís M.; Pereira, Maria João; Rodrigues, Pedro; Lopes, Rui Pedro
    We want to create a working tool for mathematics teachers and a corresponding learning tool for students, namely a graphical simulator of mathematical algorithms (GraSMa). To achieve it we try two different strategies. We started by annotate manually the original algorithm with inspector functions. Now we are testing a new approach that aims to automatically annotate the original code with inspector functions. To achieve this we are developing a language translator module that enables to comment automatically any code written in Octave language. The run of the annotated code gated by one of these two ways, records in a XML...

  5. Web 2.0: Google docs no processo de ensino e aprendizagem

    Miranda, Luísa; Morais, Carlos; Alves, Paulo; Dias, Paulo
    Nesta reflexão referem-se algumas das características da Web 2.0 e apresenta-se uma experiência de utilização do Google Docs por uma amostra de alunos do ensino superior, no contexto formal de ensino e aprendizagem. Sobre a utilização do Google Docs salientam-se as opiniões da professora acerca do trabalho desenvolvido pelos alunos e as percepções dos alunos identificadas a partir das respostas dadas a um questionário construído para o efeito. De acordo com a opinião da professora, o Google Docs é uma ferramenta de edição colaborativa com grandes potencialidades, principalmente para acompanhar os alunos nas suas actividades associadas ao estudo de cada...
