Beyond Addresses: IPv6 Value for the GIG

This paper provides responses to some common misconceptions about the value of IPv6 for DoD and the information industry at large. It then describes net-centric benefits of implementing IPv6 with the emphasis on machine-to-machine communications in two environments. IPv6-based "large machines", defined here as having reliable power supply and adequate processing capacity, are making their way into mobile and grid communications. In contrast, while the multiplicity of sensors and other "small machines" makes them perfect candidates for IPv6-based networking, their limitations in processing and transmission power require new architecture approaches. The paper reviews IPv6 standardization work in the global grid forum and IETF and emerging IPv6 applications. It then affirms the strategic value of the GIG transition to IPv6.
