This paper aims at introducing some emerging technologies and illustrating how they could be ported on both tactical and civil protection networks, allowing both functional and structural improvement. In the past years, ‘ordinary’ networking technologies have made dramatic progress in topics that were previously assumed as marginal, such as anonymity and data persistence. In this evolutionary perspective, an effort could be made to port this subset of civil technologies to more challenging networking environments. The peer-to-peer (p2p) networking paradigm offers interesting solutions for organizing both the application-level interaction and the signalling/resource reservation phase, as well as the effective delivery of a service. Due to its intrinsic delocalization characteristic, it also offers a set of solutions for anonymous data exchange, and helps hiding the routing phase. In another respect, but even more consistent, zero configuration networks allow keeping up and running the infrastructure, by reducing the needs of skilled technicians or network administrators to the minimum. This technology allows performing configuration and maintenance in a semi-automatic way, avoiding waste of time during tactical operations and preventing the occurrence of mistakes in panic situations. The paper highlights the main aspects and discusses a specific example in the deployment of application-level service quality over an ad hoc network scenario. Copyright © 2006 John Wiley & Sons, Ltd.
