Several distributed real time applications require fault tolerance apart from guaranteed timeliness. It is essential to provide hard guarantees on recovery delays, due to component failures, which cannot be ensured in traditional datagram services. Several schemes exist which attempt to guarantee recovery in a timely and resource efficient manner. These methods center around a priori reservation of network resources called spare resources along a backup route. In this paper we propose a method of segmented backups which improves upon the existing methods in terms of resource utilisation, call acceptance rate and bounded failure recovery time. We demonstrate the efficiency of our method using simulation studies.
