Abstract(s)
As redes de telecomunicações progrediram notavelmente nos últimos oito anos, o que permitiu a convergência de diferentes serviços suportados por uma única infraestrutura de rede. Após o sucesso no mercado de telecomunicações, a arquitetura multi-protocol label switching (MPLS) também está a revolucionar o mundo das empresas ligadas ao sector designadas por utility. Estas empresas procuram, essencialmente, fortalecer a segurança nas suas redes privadas (virtuais) que interligam as suas diferentes instalações.
A arquitetura MPLS permitiu que a Empresa de Eletricidade da Madeira (EEM) alcançasse os seus objetivos e os requisitos definidos inicialmente na implementação dos serviços na nova rede. A sua instalação foi projetada para ser de baixo custo e, além disso, dispor de: (i) uma elevada eficiência operacional; (ii) ser flexível; (iii) ser confiável; (iv) ser segura; (v) e possuir um nível de controlo sem precedentes. É uma solução que admite interoperabilidade entre diferentes protocolos numa plataforma baseada na comutação por rótulo, com elevado sucesso na capacidade de transportar voz com qualidade de serviço. A arquitetura MPLS simplifica e otimiza a troca de pacotes e fornece uma maior capacidade de gerir o tráfego e evitar congestionamentos.
Esta trabalho pretende explicar os procedimentos e as escolhas na implementação associados à migração de uma rede de arquitetura hierarquia digital plesiócrona/síncrona para uma arquitetura MPLS. Estas escolhas admitem integrar futuras soluções que o mercado venha a disponibilizar, no sentido de procurar a modernização das infraestruturas elétricas da EEM.
Telecomunications networks have progressed remarkably in the past eight years, which has allowed the convergence of differents services supported by a single network infrastructure. Following the success in the telecom market, the multi-protocol label switching (MPLS) architecture is also revolutionizing the world of utility companies connected to this market. These companies are essentially looking to strengthen security in their (virtual) private networks that connect their facilities. The MPLS architecture has allowed Empresa de Eletricidade da Madeira (EEM) to achieve its initially defined objectives and requirements in the implementation of the services in its new network. Its installation was intented to be low cost, while also allowing for: (i) an elevated operational efficiency; (ii) flexibility; (iii) reliability; (iv) security; (v) and an unprecedented level of control. It is a solution that allows for interoperability between different protocols on a labeled comutation based platform, with a high level of success in the transportation of voice with high quality of service. The MPLS architecture simplifies and optimizes the packet exchange and allows for superior traffick and congestion management. This thesis will explain the procedures and implementation choices associated with the migration of a Plesiochronous/Sinchronous Digital Hierarchy architecture to an MPLS architecture. These choices and procedures allow for the integration of future network solutions in the forseable future, and permit the continued modernization of EEM's electrical infrastructure.
