Pre-configured polyhedron based protection against multi-link failures in optical mesh networks

Area of Science:

• Telecommunications Engineering
• Network Reliability
• Computer Science

Background:

• Traditional optical mesh network protection focuses on single or dual link failures.
• Existing strategies often lack efficiency in spare resource utilization and robustness against multiple failures.
• Optimal network structures for link protection often involve k-regular and k-edge connected designs.

Purpose of the Study:

• To propose a novel pre-configured polyhedron-based protection structure for optical mesh networks.
• To address the challenge of simultaneous and sequential random multi-link failures.
• To improve spare resource efficiency and failure robustness in network protection.

Main Methods:

• Design of a novel pre-configured polyhedron-based protection structure.
• Evaluation of the structure's performance under probabilistic link failure scenarios.
• Comparison with existing ring-based and subgraph protection methods.

Main Results:

• The proposed polyhedron-based structure effectively protects against simultaneous and sequential random link failures.
• Demonstrated improved spare resource efficiency compared to previous approaches.
• Outperformed ring-based and subgraph protection in key performance metrics.

Conclusions:

• The novel polyhedron-based approach offers a superior solution for multi-link failure protection in optical mesh networks.
• This method enhances network reliability and resource management.
• It represents a significant advancement over existing link protection strategies.
