Behnaz Arzani, Sina Taheri, Pooria Namyar, Ryan Beckett, Siva Kesava Reddy Kakarla, Elnaz Jalilipour · 2025
Raha is the first general tool that can analyze probable degradation of traffic engineered networks under arbitrary failures and traffic shifts to prevent outages. Raha addresses a significant gap in prior work which consider only (1) ≤ k failures; (2) specific traffic engineering schemes; and (3) the maximum impact of failures irrespective of the network design point.
