AI Technical Summary

Technical Problem

Existing technologies struggle to reproduce cascading failures in large-scale routing and switching systems, making it impossible to effectively assess the vulnerability of routing and switching systems to cascading failures, especially under the complex interactions between routing nodes at scales of thousands or tens of thousands.

Method used

A cascading failure vulnerability testing system is adopted, including a routing switching module, a fault/attack event simulation module, and a vulnerability testing module. It simulates routing link bandwidth scaling, routing node function reconstruction, and fault/attack events in a virtualized environment, and performs tests and evaluations, including simulations of node failure, link failure, routing update storm, and congestion attacks.

Benefits of technology

It enables cascading failure vulnerability testing of large-scale routing and switching systems in a virtualized environment. It can simulate destructive factors such as routing update storms and traffic redirection, locate vulnerabilities, evaluate the performance degradation of the system under failure/attack, and support high-fidelity and large-scale network testing.
