Defense Info. Infrastructure Engineering and Integration
Abstract
The Defense Information Infrastructure Engineering and Integration effort encompasses two projects, the DoD Information Network (DoDIN) Systems Engineering Support and Modeling and Simulation End-to-End (E2E) Architecture. • Modeling and Simulation and End-to-End (E2E) Architecture: Within the Modeling and Simulation End-to-End Architecture project, there are two major activities: Modeling and Simulation and Enterprise Architecture. • Modeling and Simulation The Modeling and Simulation activity provides systems engineering and E2E analytical functions for DISA and its customers, ensuring integrated capabilities fulfill warfighter mission requirements. Ongoing beneficiaries of these network modeling, simulation, and analysis capabilities include: Services and Regional Combatant Commands (COCOMs): Receive modeling analyses and recommendations for architecture changes such as circuit rerouting due to Military Construction and planning for additional sites and the increased capacity for the Pacific theater. DoD CIO and Services: Receive modeling projections for the utilization of new classified desktop and mobility services to be migrated to cloud environments. DoD agencies: Receive training and support on the Joint Communications Simulation System, which is the system used to model network and applications. Additional activity resolves near term (one to three years) high-priority technical issues, as defined by DoD CIO and DISA, that impact operational capabilities, affecting DoDIN E2E interoperability and performance. For example, resolution of poor M365 Teams performance or planning for new high bandwidth routers. Additional activities include development and testing of models to simulate planned changes to enterprise services, to include migrating DISA enterprise services to cloud architectures, adding capacity to support new Fourth Estate customers, and completing network changes to support enhanced security. • End-to-End (E2E) Architecture The E2E Architecture effort establishes Enterprise Architecture (EA) development standards, documents and generates needed IT architecture artifacts to provide E2E interoperability and performance analysis, and systems engineering support for architecture evolution across DISA. DISA works with its customers to ensure integrated capabilities can fulfill warfighter mission requirements and continuously revise these Enterprise Architectures to meets the needs of the department. Some of the ongoing EA activities and projects include the follow areas: - Develop EA development framework, EA taxonomy and associated templates to support agency-wide DoD Architecture Framework (DoDAF)-based architecture development and model-based systems engineering (MBSE) requirements in a standardized, effective way to meet the program and agency mission needs. - Help agency develop enterprise level architectures to support the agency’s mission critical and high priority projects. Examples of work include the development of the DISA Zero Trust Reference Design (ZTRD) architecture; DISA enterprise Privileged Access Management (PAM) solution architecture development and AoA analysis; DOD 5G architecture documentation, DISA Robotics Process Automation (RPA) architecture; DISA DISN Out-of-band (OOB) Management Network architecture and AoA, and other emerging requirements from the agency senior leaders. - Develop capabilities and automated tools to support E2E architecture assessment and analysis in support of data-driven decisions. Examples of activities include developing automated cybersecurity assessments, architecture assessments for future architectures (e.g. SIPR 2.0), and DISA Common Enterprise Service (CES) analysis and recommendations study. • DoD Information Network Systems Engineering Support: The DoDIN Systems Engineering and Support project performs research, development, and experimentation of emerging technologies to fill capability shortfalls and technology gaps. Through conducting Technical Exchange Meetings (TEM) with other DoD components, Program Management Offices, and Technical Directors, DISA identifies gaps and shortfalls, pursues innovative solutions, and engages industry for commercial best practices. The DoDIN Systems Engineering and Support project supports technical system engineering reviews for enterprise products and services and resolves gaps related to Machine Learning/Artificial Intelligence (AI), Classified and Unclassified mobile access, Quantum Resistant Cryptography (the cryptography used to authenticate and secure data-in-transit that is susceptible to attacks), Enterprise Architecture development, Cyber Defense, and other technologies.

- Change Summary Explanation
- The decrease of -$0.493 in FY 2023 is due to the Small Business Innovation Research (SBIR) / Small Business Technology Transfer (STTR) The decrease of -$6.855 in FY 2025 is primarily due to the conversion of 33 RDT&E positions to O&M positions. The converted positions include computer scientists, interdisciplinary and electrical engineers, and IT specialists, whose primary focus is on architectures, technical standards, and concept and requirements evaluation support for the Emerging Technology. Additionally, savings realized in the commercial solution for Quantum Resistant Cryptography Crypto Discovery in the Emerging and Commercial Technologies program contributed to the decrease.
