Long-Haul Communications - DCS
Abstract
The Defense Information Systems Network (DISN) is the Department of Defense's (DoD's) consolidated worldwide telecommunications infrastructure that provides end- to-end information transport for DoD operations to the warfighters and the Combatant Commanders with a robust Command, Control, Communications, Computers and Intelligence information long-haul transport infrastructure. The DISN, seamlessly spanning the full spectrum from terrestrial to space and strategic to tactical domains, provides the interoperable telecommunications connectivity and value-added services required to plan, implement, and support all operational missions, anytime, and anywhere. DISN services reach the edge of the communications network. The DISN delivers an integrated platform consisting of DoD's core communications, computing, and information services, as well as integrating terrestrial, subsea, wireless, and satellite communications into a network cloud that is survivable and dynamically scalable. The Defense Red Switch Network (DRSN) is a global, secure voice service providing the President, the Secretary of Defense, the Joint Chiefs of Staff, the Combatant Commands (COCOMs) and selected agencies with Nuclear Command, Control, and Communications (NC3) secure voice and voice conferencing capabilities and higher classification levels. The DRSN consists of Military Department and Agency-owned secure voice switches connected by a DISA provided transport backbone. The RDT&E funding supports the following efforts: DISN Networking - Tech Refresh (TR) (formally known as Next Generation Networking Technologies): Provides engineering technical expertise to update the global network with the latest technologies. DRSN: Supports Peripheral and Component Re-Design to continue interoperability between DRSN and its operators. This capability is not commercially available and satisfies unique military requirements for multi-level secure voice services and conferencing capabilities. Additionally, RDT&E funding supports the development, testing, and fielding of a prototype of the modern multi-level secure voice and video (MLSV2) conference capability, providing a replacement for DRSN Conference Management capability. The MLSV2 prototype effort will modernize voice, video and chat conferencing capability providing a flexible and interoperable capability through standardization of protocols and interfaces as well as orchestration between hardware (HW) and software (SW). DoD Mobility: The DoD Mobility program performs research, testing, and evaluation of the virtual/zero desktop infrastructure and applications that will enable the warfighter login to any device, anytime, anywhere. The virtual/zero desktop infrastructure and zero-sign on experience will enable the warfighter to access mobile device applications by entering credentials once. The warfighter will then be automatically verified as he or she accesses additional applications. Additionally, it supports the continued evolution and expansion of Unified Endpoint Management Capabilities for unclassified and classified mobility within the Department. The Unified Endpoint Management Capabilities are a class of software tools that provide a single management interface for mobile devices, enhancing user experience for the warfighter and COCOMs. The Mobility program is also expanding research on Derived Credential capabilities, which will allow for the automation of the operations, administration, maintenance, and provisioning functions of unclassified and classified mobile endpoints.
