A cost-based admission control and routing scheme admits an arriving request on the minimum cost route if this cost does not exceed the cost of the request, and rejects the request otherwise. Cost based strategies naturally arise as a result of optimization of the network performance or incorporating Quality of Service (QoS) requirements into the admission and routing processes. In the former case the implied cost of the resources represents expected future revenue losses due to insufficient resources to service future requests. In the latter case the cost of a route represents the expected level of QoS, e.g., bandwidth, delay, packet loss, etc., provided to the request carried on this route. This paper explores different approaches intended to guard against adversarial uncertainty, i.e., worst case scenario, with respect to the resource costs lying within known confidence intervals. We assume that the network minimizes and the adversarial environment maximizes the loss or risk resulted from non-optimal admission and routing decisions due to the uncertainty. In a symmetric case we explicitly identify the optimal network strategy by solving the corresponding game of the network against environment.
