The Defense Information Systems Network (DISN) is the telecommunications infrastructure that provides end-toend information transfer for all fypes of military operations. DISN Deployed is that portion of the DISN which supports the deployed warJighter by providing connectivity to the sustaining base in the Continental United States and elsewhere. The DlsN Deployed Pilot Network (DDPN) project is intended to provide flexible, affordable communications support to deployed, tactical CINC/JF users. The pilot network approach allows feedback from operational users on operational utility of upcoming systems, development of valid plans and system designs, and a near term operational capability, The DDPN will demonstrate and implement capabilities that make more efficient use of limited military satellite bandwidth (particularly for bursty user traffic, such as router trafic), to use other media (such as commercial satellites) to augment this bandwidth, and to improve interoperability. This network is a joint venture between the Defense Information Systems Agency and U. S. Atlantic Command. It will use tactical Joint Task Force units, such as the Air Combat Command, the Joint Communications Support Element, 18th Airborne Corps, and the USSMt. Whitney command, control, and communications ship to perform a series ofproof of concept demonstrations over a period of several months. Asynchronous Transfer Mode (ATM) switches and SATCOM network control equipment will be installed in the deployed facilities of tactical participants. The combination of ATM, Control, and use of Defense Satellite Communications System (DSCS) and commercial satellites will provide a responsive approach for real time communications resource management by the deployed JTF commander. The system also provides a seamless interface to the strategic DISN network (which is migrating to ATM). At the conclusion, it is expected that the systems could be used operationally. .O IntroductionThe DDPN provides the joint warlighter with a capability never before enjoyed by a deployed tactical commander. It provides the capabillty for near real-time bandwidth management (also known as "Bandwidth on Demand) on Defense Satellite Communications Systems (DSCS) and commercial satellite systems. It also provides the capability for tactical users to interface directly into strategic wide area networks (WAN) such as the DISN ATM Services. The DDPN program will demonstrate and evaluate certain aspects of future DISN plans, and it will introduce advanced technology capabilities such as ATM switches for tactical Commanders-in-Chief (ClNCs). The main goal of using ATM is twofold: to support the use of interoperable equipment and to optimize the bandwidth through efficient use of scarce transmission circuits.Many of today's networks use Time Division Multiplexing (TDM) multiplexers which do not conform to a standard. As a result, each vendor uses a proprietary scheme for its multiplexing equipment. Using ATM for the DDPN will demonstrate the capability to support legacy circuits ...

The current Department of Defense (DoD) satellite communications architecture relies heavily on point-topoint, circuit-based communications technology, which is an inherently inefficient use of bandwidth resources. The current Global War on Terror (GWOT) and Operations Iraqi (OIF) and Enduring Freedom (OEF) demand a more efficient and scalable infrastructure to support Warfighter transformation. To meet these emerging requirements, the Defense Information Systems Agency (DISA) DoD Teleport Program Office (TPO) is building an initial transformational net-centric architecture by the end of Fiscal Year (FY) 2005 with significant upgrades starting in FY2006. The DoD Teleport system provides the deployed Warfighter access to the Global Information Grid (GIG) by linking the space and ground segments through a worldwide, pre-positioned military and commercial satellite communications infrastructure. Through multiple radio frequency (RF) media (military and commercial bands), Teleport provides inter-theater reach-back into the Defense Information Systems Network (DISN) and Service Command, Control, Communications, Computer, and Intelligence (C4I) systems, as well as intra-theater communications support for tactical users. These interfaces enable the seamless, interoperable, and secure transport of command and control (C2), intelligence, surveillance, reconnaissance (ISR), and mission critical information supporting Warfighter global operations.The TPO net-centric Teleport architecture converges all the voice, video, and data requirements into a single Internet Protocol (IP)-based transport system, consisting of: 0 0 0 Satellite IP-based networking modems, A "black" convergence router suite, and A Voice over IP (VoIP) gateway for unclassified voice.This architecture, combined with the Global Network Operations (NetOps) construct, will enable significant bandwidth efficiencies for greater reach-back and enhanced warfighting capabilities through dynamic bandwidth allocation required for advanced capabilities such as unmanned aerial Intelligence, Surveillance, and Reconnaissance (ISR) missions.As part of the Department's transformation, the Teleport net-centric and circuit-based architecture will exist in parallel for some time to enable a gradual transition by the deployed warfighter. This architecture will be implemented in two phases beginning with a Limited-IP design at two sites in FY05 followed by a worldwide implementation at all DoD Teleport locations. This paper highlights the implementation and intended operations of the new, netcentric Teleport. BACKGROUNDThe Joint Requirements Oversight Council (JROC) approval of Teleport Generation One and Two Operational Requirements Documents (ORD) validated an operational need for the rapid establishment of C41 connectivity in support of worldwide operations.Teleport is a telecommunications collection, transport, and distribution point providing the deployed Warfighter with multi-band and multi-media satellite communication capability and seamless access to terrestrial compon...
