European Public Protection and Disaster Relief (PPDR) organizations have similar needs for communications. A common network for PPDR creates synergy and makes interoperability possible. This paper presents a new highly redundant and secure data communications network solution for Public Safety Communications (PCS). The solution is decentralized and communications paths are redundant. Even if the network layer is shared with different users or different use purposes all communications remains secured and access controlled. Distributed Systems intercommunication Protocol (DSiP) offers all of these features in a single solution.
