USCENTCOM CCJ6 Network Engineering Study

Abstract

Over the last five years, the US and Coalition troop presence within the US Central Command (USCENTCOM) Area of Responsibility (AOR) has increased in support of various operations, including Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF). This buildup has resulted in the expansion of the satellite, ATM, fiber, and IP based networks within the CENTCOM AOR to support the Command, Control, Communications, Computers, and Intelligence (C4I) capabilities of the deployed warfighters. However, the rapid expansion of the CENTCOM network coupled with inconsistent network policies between the US Military services has resulted in the deployment of a less than optimal network architecture. In 2005, the CENTCOM J6 proposed an end-to-end engineering study to assess the state of the USCENTCOM Joint Theater C4I enterprise network. This study was meant to encompass all aspects of network operations in the CENTCOM AOR including transmission media, voice switching, data network routing, NetOps, and bandwidth management at the Defense Information Systems Network (DISN) Tier 0 and Tier 1 locations. As a result, three key areas of the CENTCOM network were analyzed: satellite and ATM transmission paths, Promina multi-service access platform utilization, and IP network topology including routing and switching protocols. Technology and policy enhancements were also analyzed to see how they could be used to improve the current CENTCOM network architecture.
