A Comparison on Bandwidth Requirements of Path Protection Mechanisms
A large variety of resilience mechanisms are known today. However, often the used resilience mechanisms are not adapted to the network operator’s and customer’s needs. For this, a detailed analysis and a comparison of resilience mechanisms and capacity requirements is needed. In this paper we analyze the capacity requirements of three widely used shared path protection mechanisms with each other: shared global path protection, shared local link protection and shared local to egress protection. Additionally we present an optimization approach based on linear programming to obtain optimal working and resilience path configurations for a given network structure and apply these optimizations to different case study networks.
