3.3 Information Management and Distribution

3.3.1 Warfighter Needs

This subarea encompasses Warfighter needs and capabilities related to information warfare (IW) and information systems. IW and information systems include information, information based processes, information systems and computer based systems either individually or in combination with each other. The Joint Chiefs of Staff (JCS) C4I for the Warrior Initiative describes a global infosphere providing the right information, at the right time, in the right place. The key to providing this capability is a distributed information management and distribution system that forms the backbone information infrastructure of all future C4I systems. Many capabilities (not currently available) will be an integral part of this information environment. Providing technologies that allow automated, adaptive, and robust information resource management, means we can free up the warfighter from the mundane and tedious tasks required to review and distribute information. Incorporating a context-based, rather than a message-based approach, information synchronization and management can be formally automated allowing warriors (especially those at the fighting echelons) to concentrate on mission execution rather than on complex computer operations. Automated collaboration of mission planning and monitoring of plan execution can continue at all levels and in real time.

3.3.2 Information Management and Distribution Overview

3.3.2.1 Goals and Timeframes. Development of the required warfighter capabilities for Information Management and Distribution necessitate development in the constituent areas of Distributed Environments, Information Services Management and Assured Information Services. These technology efforts will provide the warfighter with the ability to: (1) access mission-critical data from any location on the globe in a location transparent manner, (2) collaborate on mission plans at all levels and monitor execution in real-time, (3) assess mission plans through rehearsal using synthetic environments, (4) assure continuation of mission critical functions and survive loss of resources by dynamically reconfiguring where functions are executed and how information flows, (5) provide reachback from deployed forces to garrison and support units, (6) support interoperability among both joint and coalition forces, (7) support extension of the information backbone to highly mobile, deployed forces through the integration of mobile distributed computing nodes, and (8) maintain access control, authentication, integrity and availability of classified data in a distributed information environment accessible by users with differing clearances and needs to know. Figure III.8 below illustrates the anticipated progress. A roadmap that focuses on the linkages and key relationships associated with the corresponding DTOs is provided in Section 4.

3.3.2.2 Major Technical Challenges. The critical technical challenges fall into the areas associated with the infrastructure for the Distributed Environments, mechanisms to support Information Services Management which reside within the distributed environment, and the ability to deploy Assured Information Services. In the Distributed Environments infrastructure area the critical technical challenges are (1) scalability to several thousand nodes and schedulability of time critical operations which are physically dispersed across large geographic areas, (2) varied user populations and applications, (3) multiple processor types, (4) capabilities and configurations, and (5) integration of both real-time and non real-time operating environments within the same overall system. An important issue is compatibility with emerging commercial system standards and heterogeneous computing bases while retaining DoD's desired operational capabilities. (DoD's needs are not always within commercial industry perceptions of requirements and/or priorities.).

To provide the necessary Information Services Management within the distributed environment requires the development of mechanisms for managing all types of data both on individual hosts as well as across the distributed environment. To attain this capability the critical technical challenges to be met include: (1) developing data models and storage and retrieval architectures capable of handling all modalities of data in a seamless way, (2) merging and synchronizing time-dependent and non-time-dependent data, (3) developing intelligent agents capable of autonomously navigating complex database structures and extracting information for a user, (4) developing natural language and other non parametric interfaces to support "intuitive" access and retrieval of data from the database management systems (DBMSs), (5) developing adaptive information distribution techniques based upon context based as opposed to message based distribution, (6) using the information context for smart distribution over low bandwidth communications in order to selectively control the quantity of information exchanged, (7) providing capability to respond to complete information exchange failures, and (8) scaling these information distribution techniques to large systems of communications nodes.

The key to developing Assured Information Services is adaptivity within the distributed environment to allow dynamic response to varying loads of crisis management or system failure, and protection of the information within the system from attack or compromise. The critical technical challenges include: (1) security mechanisms for multi-clustered, real-time heterogeneous distributed environments, (2) adaptivity mechanisms which support the selective application of fault tolerance and fault avoidance strategies, (3) reconfiguration mechanisms to support graceful degradation, (4) replication mechanisms to insure the consistency of information, (5) intelligent resource managers to dynamically respond to crisis overloads, and (6) system architectures that permit the secure use of Commercial Off-the-Shelf (COTS) computers, software, and networks.

3.3.2.3 Related Federal and Private Sector Efforts. In many ways the information environments for the industrial, commercial, and financial communities mirror the military information environment. As a result there are leveragable development activities in the commercial sector addressing many of the same technical issues as the military. Global corporations and financial institutions have the need for global data access. Their multi-national status requires support for heterogeneity. Movement of global markets requires very rapid response to change and guaranteed availability. This creates the need for similar distributed information environments which provide location transparent access to globally distributed data. Initiatives such as the Object Management Group Common Object Request Broker Architecture, and the Open Software Foundation Distributed Computing Environment are providing commercial standards for distributed information environments which will guide the evolution of commercial product lines. They will also have a major impact on future military systems which will be primarily COTS based. The need to protect proprietary information and financial data demands information system security. Here the commercial sector has capitalized on DoD investment in MLS and has developed commercial products for secure operating systems, secure database management systems, intrusion detection systems and secure system design tools. Several federal and private organizations are pursuing efforts for assured information services. Both the National Security Agency (NSA) and National Institute of Standards and Technology (NIST) continue to be leaders in the development of information systems security mechanisms. The National Aeronautics and Space Administration (NASA) and the Department of Energy (DOE) did pioneering work in the areas of fault tolerance and high assurance systems. A number of universities under DoD, National Science Foundation (NSF) and private sponsorship have done extensive work in fault tolerance and system integrity.

3.3.3.1 Technology Demonstrations

3.3.3.1.1 Distributed Air Operations Center Prototype. Demonstrate the application of distributed computing and distributed database management tools and systems to operational requirements of the Air Operations Center (AOC) that performs force level tactical air planning. The prototype will demonstrate how the functions of the air operations center can be physically dispersed over a local or wide area and still retain the integrated functionality of collocation, as well as uniform accessibility to all required databases. This demonstration contributes to the fulfillment of DTO IS15.

3.3.3.1.2 Portable Command and Control for the Joint Task Force Demonstration. Demonstrate a supportable, global grid-based, C4I software technology base that will provide distributed generation, analysis, rehearsal, and execution of Joint strike plans and crisis actions plans in realistic JTF exercises. It will provide a JTF Commander access to multiple systems and decision aids to deliver information when and where it is needed to support operations. The near-term focus will be on demonstration of dual use technology that will support identified CinC requirements for battlefield preparation and enhance sensor to shooter connectivity. When successful , this demonstration completes DTO IS16.

3.3.3.1.3 Survivable Distributed Information Environment. Demonstrate the capability of a distributed computing system composed of inter-netted local clusters of computers to operate successfully under stress by gracefully degrading rather than failing. The goal is to provide a level of continuing mission support in the presence of sporadic and overlapping faults or anomalous behavior episodes. This capability will include dynamic repositioning of both processes and data to the remaining computational elements to provide continued mission execution. This demonstration contributes to the fulfillment of DTO IS18.

3.3.3.2 Technology Development. In the Distributed Environments technology effort, development is focused on: (1) real-time heterogeneous distributed computing environments, (2) distributed computing over high bandwidth global grids, (3) distributed computing over low bandwidth radio frequency (RF) communications, (4) distributed, object-oriented, multimedia database management, (5) optimal tasking assignment to distributed resources, (6) interoperability among distributed, federated database management systems, and (7) scalability of COTS products to very large scale DoD configurations

In the Information Services Management area , development needs to focus on: (1) adaptive resource management paradigms which allow dynamic reallocation of tasks to computing resources, (2) mechanisms to automatically control information exchange among nodes to limit the quantity of data based upon the context of the application and available communications bandwidth, (3) mediators to assist in the acquisition of information from multiple sources within the distributed information environment, and (4) integration of both real-time and non real-time control mechanisms within a single distributed environment.

In the attainment of Assured Information Services development is focusing on: (1) extension of security mechanisms in the composeability of COTS products to meet DoD needs, (2) development of adaptive security mechanisms which accommodate resource modifications in resource sets without violating security policy, (3) adaptive fault tolerance and avoidance mechanisms, (4) intelligent agents to dynamically respond to intermittent failures by reconfiguring the computing resource set, and (5) integrity mechanisms to assure the validity and consistency of information in the global environment.
