A layered communications architecture is advocated for the militarys Global Communications Grid GCG or Global Grid GG, the communications infrastructure of the Global Information Grid GIG. A seven-layer reference model consisting of Mission, Application, Service, Transport, Network, Link, and Physical Layers is introduced the GG corresponds to the Transport and Network Layers. The fundamental concept for military interoperability inherent in the GG architecture, viz., network-centricity, is explained. The importance of layering communications protocols and functions is discussed. Examples of layering communications, management, and security functions are provided.
