    Daidalos Testbed integration framework required detailed planning and implementation, constantly adapting to the demanding changes of a research project as it advances from development phase to integration phase. This paper describes the various integration and validaton efforts required to deploy an operational Daidalos Testbed infrastructure, demonstrating the effort required to achieve a successful overall integration process. With such a large scale project as Daidalos with a consortium of 49 partners, the Testbed deployment, operation and management was indeed an immense task having to create and enforce Testbed processes suitable for the efficient and effective operation of the Daidalos system during integration and validation

    Mestrado em Engenharia de Computadores e TelemĆ”ticaA Internet e as redes no seu geral estĆ£o cada vez mais presentes no nosso quotidiano. No entanto, o seu crescente uso destaca tambĆ©m algumas das suas limitaƧƵes, levando os investigadores de redes a criarem novas soluƧƵes, numa tentativa de preverem e resolverem problemas que daĆ­ possam advir. O desenvolvimento destas soluƧƵes implica que sejam realizados testes exaustivos antes que estas se tornem aptas para o uso das massas. Podem ser adoptadas diversas abordagens para a realizaĆ§Ć£o destes testes. SimulaƧƵes sĆ£o importantes como uma primeira aproximaĆ§Ć£o, contudo, nĆ£o conseguem captar a dinĆ¢mica e a imprevisibilidade de um ambiente real. A emulaĆ§Ć£o surge como alternativa, tentando colmatar essa falha, no entanto, nĆ£o Ć© eficaz na reproduĆ§Ć£o de cenĆ”rios mais complexos. A soluĆ§Ć£o poderĆ” passar pela criaĆ§Ć£o de infra-estruturas dedicadas ao teste destas soluƧƵes, denominadas de redes experimentais, permitindo realizar uma avaliaĆ§Ć£o mais profunda e fiĆ”vel das mesmas. Contudo a sua construĆ§Ć£o envolve grandes custos e as infra-estruturas caem em desuso assim que Ć© alcanƧado o produto final. Ɖ necessĆ”rio desenvolver maneiras de instrumentalizar estas infra-estruturas, de forma a optimizar estes recursos para futuros testes. Esta dissertaĆ§Ć£o centra-se nos problema evidenciados na criaĆ§Ć£o destas redes de teste, estudando as existentes formas de gestĆ£o destas redes experimentais, bem como o seu uso optimizado com vista Ć  criaĆ§Ć£o de experiencias. Pretende-se assim desenvolver no Ć¢mbito desta tese, uma ferramenta que permita aos utilizadores criarem e usarem facilmente e de forma eficiente uma rede experimental.The Internet, as with networks in general, is increasingly present in our everyday lives. However, its use also highlights some of their limitations, leading researchers to create new network solutions in an attempt to anticipate and solve problems that may arise. These solutions require exhaustive tests before they become eligible for production. Several approaches can be taken to conduct such tests. Simulations are important as first approximations; however, they fail to capture the dynamics and unpredictability of a real environment. Emulations present an alternative, but fail to reproduce more complex scenarios. Experimentation facilities must therefore be deployed, to achieve a higher level of realism. These facilities, also referred as testbeds, involve high-complexity deployment and operation, falling into disuse once they arrive at a final product. Methods of managing these infrastructures must be developed in order to avoid this waste of resources for future tests. This dissertation focuses on the problems inherent to the management of these facilities, with a focus on their users. Different approaches in network testing must be studied and the different methodologies on experimentation must be collected. An application is developed to address this problem, enabling users to create their experiments and collect results in both an organized and effective manner
