Uma rede de backbone de protocolo de Internet (IP) baseada em caminho óptico de multiplexação por divisão de comprimento de onda (WDM) é proposta como uma maneira econômica de realizar sistemas robustos de IP sobre fotônicos. O caminho óptico WDM é baseado na transmissão WDM e no roteamento de comprimento de onda. Entre roteadores de backbone IP ponta a ponta, o caminho óptico WDM, um tubo óptico robusto e grosso, é definido através de sistemas de transporte fotônico (PTS). Serão necessários PTS de classe Tera-bit para a futura rede de backbone IP e este nível de desempenho é alcançável. O roteamento da camada óptica é feito em nós intermediários, eliminando assim o roteamento elétrico pacote por pacote exigido pelos sistemas existentes. É apresentado um formato de sinal óptico que permite a transmissão econômica de pacotes IP. Os caminhos ópticos WDM acomodam diretamente os pacotes IP por meio de quadros da camada 2. A relação custo-eficácia do sistema proposto, especialmente para tráfego pesado, é demonstrada do ponto de vista da capacidade global de transporte do tráfego da rede e do custo do nó da rede. O sistema proposto é tão robusto quanto os sistemas existentes; por exemplo, mecanismo de localização de falha/degradação e proteção de rede de camada óptica são implementados. Assim, o sistema IP sobre fotônico proposto criará redes de backbone IP robustas e econômicas.

Abstract: A wavelength division multiplexing (WDM) optical path-based Internet protocol (IP) backbone network is proposed as a cost-effective way of realizing robust IP-over-photonic systems. The WDM optical path is based on WDM transmission and wavelength routing. Between end-to-end IP backbone routers, the WDM optical path, a fat and robust optical pipe, is defined across photonic transport systems (PTS's). Tera-bit class PTS's will be required for the future IP backbone network and this level of performance is achievable. Optical layer routing is done at intermediate nodes, so the electrical packet-by-packet routing required by existing systems is eliminated. An optical signal format that permits cost-effective IP packet transmission is presented. WDM optical paths directly accommodate the IP packets via layer-2 frames. The cost-effectiveness of the proposed system, especially for heavy traffic, is demonstrated from the viewpoint of the overall network traffic transport capability and network node cost. The proposed system is as robust as existing systems; e. g. fault/degradation localization mechanism and optical layer network protection one are implemented. Thus the proposed IP-over-photonic system will create cost-effective and robust IP backbone networks.
