The convergence of telephone and Internet protocol networks holds great promise, according to industry experts, leading vendors and the press. However, an increasingly converged network also increases the risk factor associated with securing voice and other real-time communication streams. These risks are not limited to Internet-protocol-based networks; traditional time division multiplexing networks also are vulnerable.

As the war on terrorism enters its fourth year, experts offer that the U.S. government can congratulate itself for successfully launching a number of bold initiatives to protect national security.

Military and government decision makers convene at the Washington, D.C., Convention Center next month to discuss requirements in current operations and to explore hundreds of technical solutions. TechNet International 2005, which takes place May 17-19, will address the issues that commanders know from experience are real challenges facing warfighters today.

There are a number of emerging technologies and methods of applying them that will help the Defense Information Systems Agency (DISA) and the U.S. Defense Department as we build the foundation for network-centric operations, two of which are convergence and Web services. DISA is pursuing the acquisition of services and capabilities employing these technologies with techniques such as capacity-on-demand and managed services.

The U.S. Army is tasked with a three-sided challenge as it seeks to transform its communications-electronics systems. The Army must continue to progress with far-reaching plans that will change the way it conducts military operations; it must respond to warfighters' urgent information technology needs in Afghanistan and Iraq; and it must incorporate changes inspired by lessons learned in those wars into its long-range efforts.

Disposable sensors, a single radar set that performs several tasks and electrical power devices that refuel from a diesel truck's gas tank are just some of the innovations that may reshape U.S. Army operations on the battlefield of the future. This research is altering the vision of the transformational force even as ongoing programs pick up speed, and it promises new and exciting capabilities to further extend the Army's battlefield supremacy.

Feedback from ongoing U.S. military operations in Southwest Asia is enhancing a key fire control and battle management system. Designed to help track friendly units and direct available artillery and air platforms against enemy forces, this software-based application is an important command and control asset and a major component for upcoming programs such as the U.S. Army's Future Combat Systems (FCS).

Setting up and maintaining a communications network in a war zone is difficult under any circumstances, but it is especially complicated in a battlespace without defined front lines. To meet this challenge, the U.S. Army is combining military systems and commercial solutions to establish a reliable network for commanders and warfighters in operation Iraqi Freedom.

A communications interface system soon may enhance the situational awareness and connectivity of U.S. Marine Corps units. The equipment consists of vehicle-mounted racks housing an interchangeable set of tactical radios, routers and configuration software that allows commanders to quickly select, change and modify their tactical data networks for specific missions. By linking a variety of radio systems into a single network, the technology permits units with previously incompatible radio systems to communicate with each other.

With updated cabling and server farms in place, the U.S. Navy is making way on a government-owned, government-operated information technology initiative that ultimately will affect more than 41,000 users in Europe, the Middle East and the Far East. During the coming months, sailors stationed at bases outside the continental United States, beyond the scope of the Navy/Marine Corps Intranet, will be coming aboard their own enterprisewide network.
