Abstract or Description

The success of the Internet has led many activities to be highly dependent on the good quality of the service that the network can provide. Failures can be very disruptive if systems without enough backup resources are in place. In this paper we propose a new way of determining how many backup resources must be provided to guarantee a given level of availability to critical services in the core of the network. The biggest impact of this work lies in how network providers design and deploy their infrastructure.
