Poster: Domino: Towards a Testbench for Stress Testing Internet Critical Infrastructure

In just a few decades, the Internet has evolved from a research prototype to a critical infrastructure for modern society and the global economy. Despite its importance, the Internet's survivability amid large-scale failures has received limited attention. We present a testbench design for stress testing the Internet's routing system. This simulation-based framework allows for flexible integration of survivability metrics, evaluation of different topologies, and assessment of protocol and architectural changes. With several illustrative examples, we show the effectiveness of our proposed testbench and make a case for stress testing as a viable approach to evaluating the survivability of inter-domain routing against evolving challenges.
