FIGURE C-4. UA PROGRESSION FROM CIRCUIT BASED TO NET-CENTRIC COMMUNICATIONS.
Themes
The following “Communications Themes” set the tone for this section and are provided to guide new systems development and legacy system migration.
.
Implement an Internet Protocol (IP) based UA networking architecture
.
Migrate point-to point circuits to an IP based network
.
Register all data with the DISA metadata repository
.
Implement network access and connectivity via JTRS enabled terminals, evolutionary terminal acquisition
.
Provide timely, reliable, secure transmission of large quantities of data with eventual migration to SCA compliant CDL, JTRS and Family of Advanced Beyond Line-of-Sight Terminals (FAB-T)
.
Provide assured, direct connectivity into the Transformational Communications System (TCS) space
backbone UA networking will incorporate the following major functional areas.
.
Routing. mobile ad-hoc routing, traditional routing, and global connectivity
.
Mobility and IPv6. mobility services for both user hosts and networks
.
Quality of Service (QoS)/Class of Service (COS). guaranteed and differentiated services for user networks
.
Network Management. management of mobile nodes and integration with other GIG network management systems
.
Information Assurance (IA). IP network security
DOD INITIATIVES
The DoD is transforming from a hierarchical, point-to-point (circuit switched) architecture to horizontally integrated, net-centric operational model. The highly successful, DoD mandated CDL program will contribute significantly to UA communications for the foreseeable future, transitioning to this net-centric configuration in the coming years. In addition, DoD has sponsored six key technology initiatives: JTRS, GIG Bandwidth Expansion (GIG-BE), Transformation Communications Architecture (TCA) SATCOM

(TSAT), Net-Centric Enterprise Services (NCES), IA programs, and Horizontal Fusion. Three of these initiatives directly impact UA development and deployment. The guidance in this appendix presumes their successful execution:
.
JTRS. successfully deploys
.
TSAT. constellation launches on schedule
.
IA. HAIPE. a key web enabled encryption device successfully enables GIG Red Edge/Black Core The heart of the new net-centric model is the IP and networking services layer functionality, which will provide significantly improved communications modes (transport). This layer will provide the information services and applications needed to ensure timely, accurate, and secure discovery of and
