DISN advanced wireless mobile services (DAWMS) in global net-centric environment for the warfighter

The defense information system network (DISN) in the global information grid (GIG) is the premier DoD global information transport backbone network. It consists of NIPRNET, SIPRNET, DSN, and DRSN, which are the major networks to provide long haul imagery, voice, video, and data transport networking services. The terrestrial-based DISN has been working with teleport and global broadcast services (GBS) to deliver classified and unclassified video, imagery, and other information products in support of e-collaboration among DISN, teleport, and GBS worldwide joint military operations. This has greatly enhanced the mobility theater-deployed warfighters and significantly contributed to the successful execution of various contingency operations. Despite these advances, important challenges remain to extend DISN broadband communications capabilities and real-time IP-based services to the disadvantaged deployed mobile end users who are on the forefront in very constrained environment. The proposed architecture framework presented in this paper, bridges the communication capacity gaps and provides critical transport capabilities that will transform future battlefield communications. A comprehensive test and assessment effort is underway to ensure the seamless, end-to-end integration of wireless services with the GIG assets for delivering C4ISR information to the edge. When deployed, the WSDN will be able to extend DISN services to fixed and/or mobile installations in theater. It will provide additional interoperable capability to joint tactical radio system (JTRS) and enhanced mobility for the warfighter information network-tactical (WIN-T) users
