Reforçar redes de backbone capazes de sobreviver contra falhas múltiplas está se tornando uma preocupação comum entre as empresas de telecomunicações que precisam continuar os serviços mesmo quando ocorrem desastres. Este artigo apresenta um esquema de recuperação de falhas múltiplas que considera a operação e gerenciamento de caminhos ópticos. O esquema apresentado emprega o escalonamento do esquema desde a restauração pré-planejada até o reencaminhamento completo. Primeiro, a capacidade de sobrevivência deste esquema contra falhas múltiplas é avaliada considerando restrições operacionais como seleção de rotas, alocação de recursos e ordem de recuperação de caminhos com falha. Os resultados da avaliação mostram que a escalada do esquema proporciona um elevado nível de capacidade de sobrevivência mesmo sob restrições operacionais, e este documento esclarece quantitativamente o impacto destas várias restrições operacionais. Além disso, as funções fundamentais do escalonamento do esquema são implementadas no plano de controle Generalized Multi-Protocol Label Switching e verificadas em uma rede óptica baseada em conexão cruzada.

Abstract: Bolstering survivable backbone networks against multiple failures is becoming a common concern among telecom companies that need to continue services even when disasters occur. This paper presents a multiple-failure recovery scheme that considers the operation and management of optical paths. The presented scheme employs scheme escalation from pre-planned restoration to full rerouting. First, the survivability of this scheme against multiple failures is evaluated considering operational constraints such as route selection, resource allocation, and the recovery order of failed paths. The evaluation results show that scheme escalation provides a high level of survivability even under operational constraints, and this paper quantitatively clarifies the impact of these various operational constraints. In addition, the fundamental functions of the scheme escalation are implemented in the Generalized Multi-Protocol Label Switching control plane and verified in an optical-cross-connect-based network.
