Value-added services in the Goal DISN

The Defense Information System Network (DISN) will be the telecommunications infrastructure for all defense information systems in the future. Its architecture consists of three major building blocks: the transport infrastructure segment; a network management segment; and a value-added services segment. The transport infrastructure will be a high-speed broadband integrated services digital network (BISDN) in a hierarchical arrangement. The network management segment will be integrated in a hierarchically-distributed structure of geographically oriented domains. The value-added services segment is yet to be defined. This paper reports on the first focused work to do that. A definition for value-added services (VAS) is established; distinctions are drawn with other network capabilities and characteristics; twenty (20) candidate VASs meeting the definition are examined, especially with respect to military application; and seventeen (17) are recommended for implementation in the Goal DISN, c.2005+.<
