Network Centric Waveform is a multimedia transport system allowing full-mesh, packet-switched IP communication networks over SHF transponded geosynchronous satellites, such as the Wideband Global Satellite constellation.
An NCW network consists of up to 255 SATCOM terminals. One terminal operates as the Network Controller, serving as the source for network time synchronization and the focal point for network control and resource. Certain network members, depending on terminal configuration and performance capabilities, may be capable of assuming the network controller function, and can also serve as store and forward hubs to assist network members that cannot close single-hop.
