A substitution network is a rapidly deployable backup wire- less solution to quickly react to network topology changes due to failures or to ash crowd e ects on the base network. Unlike other ad hoc and mesh solutions, a substitution network does not attempt to provide new services to customers but rather to restore and maintain at least some of the services available before the failure. Furthermore, a substitution net- work is not deployed directly for customers but to help the base network provide services to the customers. Therefore, a substitution network is not, by de nition, a stand-alone network. In this paper, we describe the quality of service architecture for substitution networks and discuss pro- visioning, maintenance, and adaptation of QoS inside and between the base network and the substitution network.
