The OCONUS Navy Enterprise Network (ONE-Net) is a Department of the Navy initiative to deliver comprehensive, end-to-end information and telecommunication services to OCONUS Navy shore commands by using a common computing environment for both the Non-secure IP Router Network (NIPRNet) and Secure IP Router Network (SIPRNet). ONE-Net is designated as government-owned and government-operated until the network transitions to the Next Generation Enterprise Network (NGEN) and adopts the NGEN operating model and support structure.
ONE-Net is part of the Naval Enterprise Networks (NEN) Program Office that manages the acquisition life-cycle of the Department of the Navy’s (DON) enterprise-wide information technology (IT) networks. NEN’s portfolio includes the Navy Marine Corps Intranet (NMCI), the OCONUS Navy Enterprise Network (ONE-Net) and the Next Generation Enterprise Network (NGEN) . NEN provides program management of the NMCI Continuity of Services Contract (CoSC), while continuing to develop the acquisition approach and transition strategy roadmap for NGEN’s successful implementation. NEN unifies the DON’s terrestrial networks and data management to improve capability and service while saving significant dollars by focusing efforts under one program office and one enterprise network construct.
NEN is part of the DON’s Program Executive Office for Enterprise Information Systems (PEO-EIS), which oversees a portfolio of enterprise-wide information technology programs designed to enable common business processes and provide standard IT capabilities to Sailors at sea, Marines in the field and their support systems. Established in the spring of 2006, the PEO ensures these programs maximize value to the warfighter by balancing cost with the capability delivered to the end user.

ONE-NET is a Navy-wide initiative to install a common and secure IT infrastructure to OCONUS Navy locations. It is based on the Navy-Marine Corps Intranet (NMCI) architecture and is designed to be interoperable with IT-21, NMCI, and the Global Information Grid in the near future.

ONE-NET incorporates a new network infrastructure, including servers and transmission lines with existing and new workstations to provide integrated information technology to the fleet. With ONE-NET, users will have standardized hardware and software, a centralized help desk, access to an OCONUS e-mail directory, increased information security, a standard e-mail address, and increased SIPRNET availability and remote access.

To achieve information superiority over an adversary, the IT-21 Warfighter must be able to collect, process and disseminate an uninterrupted flow of information. DoD and the Navy are deploying a global infosphere to achieve that superiority anywhere, anytime and in the performance of any mission.

ONE-NET consolidates enterprise management, which will in turn allow for streamlined resources to support the network

ONE-NET is an integrated network that consists of a standard configuration and consistent applications in a secure environment for classified and unclassified IT processes

ONE-NET is government owned and government operated (GOGO), with a possible shift to seat management in the future

Many IT services will be centralized at ITSC-FE in Yokosuka with supporting field service staff at Information Technology Operations Centers (ITOCs). All U.S. Navy ashore installations outside the United States will be affected by this new technical infrastructure.
