Goal architecture and transition strategy for the Defense Information System Network

The goal-integrated communications architecture for the Defense Information System Network (DISN) is based on open systems principles and will support multimedia workstations and multilevel security applications. Broadband integrated services digital network (BISDN) standards and services form the basic infrastructure of the goal architecture. The authors provide a framework for an economical and efficient transition from today´s communications architecture to the goal architecture in a phased approach. The trend is towards information sharing, consolidation, and integrated services (e.g., voice, data, video, leads and imagery) while capitalizing on commercial off-the-shelf services and equipment. The path to the future environment is characterized as a controlled evolutionary transition strategy based on anticipated changes in user requirements, advances in technology, and the pace of standards implementation
