Internetworking: Technical Strategy for Implementing the Next Generation Internet Protocol (IPV6) in the Marine Corps Tactical Data Network.

The Marine Corps must architect a tactical internet based on a software technology that is in transition - the Internet Protocol (IP). Development of the Marine Corps tactical internetworking system (Tactical Data Network or TDN) is progressing concurrently with the global Internet community's development of the Next Generation Internet Protocol (IPv6). Current (IPv4) and next generation (IPv6) versions of the Internet Protocol can together meet the tactical internetworking needs of the Marine Corps. IPv4 provides universal interoperability with other networking technologies and support for a wide range of services now, but without enhancements IPv4 cannot meet the long-terms needs of evolving tactical applications. IPv6 is needed to meet emerging requirements (such as secure mobility) but is not yet ready for implementation in the Tactical Data Network. Therefore the Marine Corps must build the tactical internet architecture using IPv4 and incorporate IPv6 improvements when transition is possible. Marine Corps commitment to IP is essential to ensure universal interoperability and hardware-independent evolution of tactical applications and networking technology. This work presents a tactical IP addressing plan for TDN that works with IPv4 and also facilitates smooth transition to IPv6. In concert with the other military services, the Marine Corps must develop a strategy for migrating the joint tactical internet to IPv6. The future viability of the Tactical Data Network depends on the Internet Protocol.
