Resilience under Uncertainty: Securing 6G through Stochastic Reinstantiation of RAN Functions

Gabriel Almeida, Jacek Kibi{\l}da, Joao F. Santos, Kleber Vieira Cardoso

Disaggregated 6G networks recover from cascading RAN failures by reinstantiating CUs and DUs in alternative cloud locations using two-stage stochastic optimization under uncertainty.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

our results demonstrate that our solution can achieve up to 80% higher recovery performance compared to conventional resilience mechanisms.

C2weakest assumption

The recovery process assumes that alternative cloud locations for reinstantiating CUs and DUs are always available and that uncertainty in users' locations and wireless channel conditions during failure can be adequately captured by a finite set of scenarios in the stochastic model.

C3one line summary

A two-stage stochastic optimization approach using Sample Average Approximation for adaptive reinstantiation of RAN functions in disaggregated mobile networks to maintain service under cascading failures and uncertainty.
