Daidalos Framework for Successful Testbed Integration
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
Sistema para gestĆ£o remota de redes experimentais
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 tambƩm 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 Ʃ alcanƧado o produto
final. Ć 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
