In the research on the networked control systems (NCS) the performance of the control system is assumed to be affected by network induced parameters such as delays, jitters, packet losses, link failures. In this paper a reconfiguration of the network control is presented. The upper bound delay of the transmission time of a packet is monitored with the network calculus based algorithm. A modification of the network parameters due to a failure is reflected by an increase of the upper bound value. Two reconfigurationprocedures are proposed which aim at compensating the effect of the failure on the QoS
