Abstract

Nowadays on-line reconfiguration for computer networks is pursued as an alternative approach to keep performance levels when a mal function is presented in the system. In this case, reconfiguration is proposed in three stages. Firstly, computer network presents a degradation in time communication due to the appearance of certain local faults. Secondly, based upon this scenario a strategy for on-line reconfiguration is pursued in order to cover faults where new time delays appear between elements. These delays modify the behaviour of the dynamical response of the system. During third stage, the control law needs to be modified in terms of current time delays. Therefore, in this paper, on-line system reconfiguration as multivariable and multi-stage problem is pursued based upon a quasi-dynamic scheduler that takes into account those predetermined time delays and the related control law. Control law reconfiguration is pursued as soon as structural computer network reconfiguration is taken place by using current system performance.
