A series of Hamiltonian cycle-based solutions to provide simple and scalable mesh optical network resilience

A mesh optical resilience solution has many requirements, some of which conflict with others. This article highlights the issues relevant to mesh optical resilience and the challenges of meeting the myriad requirements. A series of Hamiltonian cycle-based solutions with different efficiency, complexity, and scalability trade-offs are introduced. Solutions for moderate-sized and large networks are differentiated with the former emphasizing simplicity and efficiency, and the latter stressing resilience from multiple simultaneous failures and isolation of failure events.
