Abstract
As virtualization of Radio Access Networks (RAN) gains momentum,
understanding the impact of hardware and software disaggregation on resiliency
becomes critical to meet the high availability requirements of mobile networks.
Our paper presents an analytical model, using continuous time Markov chains, to
study the impact of virtualization and disaggregation on RAN availability. Our
evaluation, assuming typical parameter value ranges for failure and recovery
rates, points to containerized platform reliability as a constraint on vRAN
availability. We also find that with active-passive replication, increasing
hardware replication factor beyond 2 may not bring any benefits unless failover
times are reduced. We also compare the reliability of centralized and
distributed virtualized central units.
