DISN Systems Engineering Support
Abstract
Funds systems engineering of Operations Support Systems (OSS), which are comprised of the system management, network management, and element management systems. The OSS provides service support systems and network operations of the DISN and other entities. Specifically, this funding provides system engineering for the Data Mediation, Information Sharing Services for Voice, and Network Management Solutions for New DISN Element Technologies. Provides systems engineering for Voice over Secure Internet Protocol (VoSIP) Real Time Services (RTS) for the DISN-wide network element management of day-to-day operations of the DoD and serves as the core DoD wartime communications for the President and Secretary of Defense, the Joint Chiefs of Staff (JCS), the Combatant Commands, and other critical users. Provides the engineering to consolidate operational communications networks into DISN and supports the convergence of Service and Agency network services (i.e. telephony, video, etc) into the Global Information Grid (GIG). Also funds system engineering evaluations and development of critical features for Secure VoIP RTS that is beyond the features of commercial VoIP offerings. VoSIP provides SECRET high secure voice service to over 90,000 DoD users at approximately 100 user enclaves worldwide. Expanded capabilities provide greater user productivity. The active directory service will improve and speed up the ability to locate users across the network. VoSIP system engineering is not funded beyond FY 2009. Funds software development and system integration and testing for technology refreshment of the current DSS-2A Secure Voice Switch technology, with improvements to increase the capacity of the switch so that it can be used to replace the large SDS-1 model switches in the Defense Red Switch Network (DRSN) which are at end-of-life and must be replaced. There are no other viable alternatives that provide multi-level security, quality of service, assured service, conferencing and conference management, plus radio/satellite interfaces available in the near or mid-term. This funding provides incremental multi-year efforts to scale up the existing DSS-2A switch capacity so that the Services and Agencies can purchase and install the modified switch to replace their obsolete SDS-1 switches. The DSS-2A modification effort completes in FY 2011. Funds the Engineering Change Proposal (ECP) process for other DRSN peripherals such as remote phone distribution multiplexers, telephones and STE’s and Milstar systems interfaces. Secure Voice Switches must meet a number of military unique requirements for multilevel security, extensive conferencing and conference management capabilities and features, and gateway functions that are not available in commercial products. Because of the proprietary multi-level security and conferencing solutions embedded in Secure Voice Switch equipment, the only alternative to wholesale replacement is the Engineering Change Proposal (ECP) process which is used to identify and manage the development of replacement parts and peripherals that are necessary to ensure the continued supportability of the system. Substitution of a commercial product is impractical due to requirements for interoperability and security. The cost of modifying another vendor’s commercial product has been examined and would be prohibitive and no commercial vendor has expressed interest, especially considering the limited market. Starting in FY 2010, system engineering for DRSN shifts to funding and executing ECP to update switch components and peripherals to replace obsolete parts and ensure continued logistics supportability. The DTCS funding will provide engineering, development, and testing resources to transition the Naval Surface Weapons Center’s (NSWC) Technology Prototype to a fully fielded operational capability. The Prototype Service and 100 handsets are already fielded as part of the NSWC Pilot effort. Follow-on Research and Development (R&D) efforts include additional handset procurement of 2 handset variants (Command and Control and Secret Command and Control), Network Management System, User Control Interface, and Satellite Software Modifications. Life-Cycle support issues will be addressed through the Defense Working Capital Fund.
