This document provides to the Defense Communications Agency the results of a user requirements collection and analysis effort made for the purpose of determining the need for a specialized gateway that would interconnect communities with different security characteristics (such as allowing multilevel secure, classified hosts operating at the unclassified level to communicate with hosts in the unclassified segment). Section 2 of this report discusses the evolution of the Defense Data Network with regards to interoperability and security. Section 3 reviews the results of a survey of DDN subscriber requirements describing describing the survey method and postulating the numbers and types of gateways required. Section 4 is an analysis of the potential functions to be performed. Section 5 presents a survey of current commercial & government gateway technology. Section 6 presents an analysis of the numbers of TGG required for the DDN.
