The connection admission problem in internet networks: An optimal control approach

This paper focuses on Connection Admission Control Problem and it proposes an innovative approach for its solution. Starting from an abstract network modelling, the Resource Management problem is formulated in a technology independent fashion allowing the proposed concepts to be applied to any wireless and wired domain. Basing on appropriate considerations, the authors propose an approach in which CAC procedure is decoupled from the other Resource Management procedures, but still cooperates with them in order to guarantee the desired QoS requirements. Moreover, the proposed CAC control scheme is implemented on a feedback loop on the basis of a convenient optimality criterion aiming to maximize total throughput, while respecting a set of constraints accounting for the QoS requirements. Finally, this approach is based on suitable performance measurements which, by using proper predictors, allow to forecast the domain dynamics in the next future.
