Service Reliability Assurance Technology Based on N-X Analysis

In this paper, reliability assessment technology based on N-X service impact analysis is studied to accurately evaluate the risk value of power communication network service under N-X maintenance mode when the maintenance object is in maintenance state. On this basis, N-X service risk analysis is studied under the maintenance mode. Under the maintenance condition, the link or node equipment is determined to be in the maintenance state through maintenance, and the service route will be changed accordingly. All the link and node equipment that cannot be repaired are given to complete the maintenance task with low risk. Study the service reliability assurance technology based on N-X risk, develop the evaluation indexes related to network service protection, simulate the network fault X in the network, statistically evaluate the affected situation of the service, and carry out routing and protection upgrade and optimization for the service affected by the over-threshold or fault.
