Many important issues must be considered as the Navy begins to convert its communications to a mullet-media network based on the ISO layered architecture. naming and addressing techniques required to meet Navy communications requirements are an important set of considerations. naming and addressing cannot be dealt with in isolation but requires a systems approach which considers issues relation to directory services, routing services and multipeer data transmission protocols and services. the protocols and services developed by the commercially motivated ISO standards committees often require extensions and/or interpretations to meet DoD requirements. this project will take a system's approach to the problem of naming and addressing. Navy requirements will be determined, a literature survey will be conducted and an annotated biography prepared, and trade studies will be conducted leading to a recommended strategy for naming and addressing Naval communications networks. this recommended approach will be based upon the results of five special studies: name structure, directory services, routing services, address structure and multipeer data transmission.
