AI Technical Summary

Technical Problem

Existing network configuration methods are unable to quickly adapt to changing threat environments when facing network attacks, resulting in cumbersome recovery processes and long network service interruptions, which affect network performance stability.

Method used

To construct a configuration scheme with optimal network resilience, the relationship between logical network edges and physical network edges is mapped, and the physical network edges with the largest number are selected for backup and expansion. Backup is carried out under the constraint of adding optical cable length, and the network load configuration is optimized to improve network resilience.

Benefits of technology

It effectively improves the network's self-healing ability in the face of attacks, ensures the availability and performance stability of network services, and reduces network downtime.

Abstract

The application discloses a network load expansion planning method and system based on network resilience recovery degree, and the method comprises the following steps: constructing a network configuration scheme with optimal network resilience, and obtaining a mapping relationship between logical network edges and physical network edges in the network configuration scheme; arranging each physical network edge in the network configuration scheme in descending order according to the number of mapped logical network edges, screening out N physical network edges with the largest number of mapped logical network edges as expansion candidate physical network edges; under the constraint of the length of the new optical cable that can be added, selecting the candidate physical network edges with more mapped logical network edges for backup to obtain an expanded network configuration scheme. The application is applied to the field of network load configuration and expansion, and the part of the physical network edges with the largest number of mapped logical network edges are backed up and expanded, so that the best attack scheme of the rational opponent can be effectively coped with, and the availability and performance stability of the network service can be effectively ensured.
