CONTINGENCY DISASTER RECOVERY PLANNING FOR TRANSMISSION-SYSTEMS OF THE DEFENSE INFORMATION-SYSTEM NETWORK

This paper provides recommendations for the enhancement and protection of the Defense Information System Network (DISN) for disaster recover y and contingencies. The DISN is a worldwide Defense Department networ k designed to serve consolidated and integrated communication requirem ents of the defense services and agencies. The ability to recover from disasters and allow for contingencies must be inherent in the design of this network. Basic design aspects of the DISN are described, along with several complementary programs for disaster recovery planning be ing implemented by the Office of the Manager, National Communications System (OMNCS). Both hostile and nonhostile threats are examined to se t the stage for recommendations that follow. Techniques for disaster a nd contingency preparedness are described that will improve DISN survi vability and disaster recovery. Specific technologies are considered f or provision of independent orderwires and backup transmission systems . An interface device designed for transmission recovery is recommende d for both satellite and terrestrial media. Other specific recommendat ions are made for network management within the various hierarchical l evels of DISN management.
