Failures in modern communication networks are a factor affecting the indicators of economic efficiency of the organization. The main objective of the project is to study the failure of network elements in order to improve the reliability and resiliency of communication systems by making changes to its structure. The selected recovery strategy for a failed item can significantly affect reliability performance. Results are important to ensure the required level of fault tolerance with limited operating costs.
