OPNET to Build Network Common Operating Picture for USCENTAF.

Business Editors

BETHESDA, Md.--(BUSINESS WIRE)--Sept. 3, 2003

OPNET Technologies, Inc. (NASDAQ:OPNT), a leading provider of management software for networks and applications, today announced that it will build a Network Common Operating Picture (NETCOP) system for US Central Command Air Forces (USCENTAF), based on OPNET's SP Guru technology and data stored in OPNET VNE Server.

The delivery order provides for multiple phases of development for a NETCOP system, using an existing contract vehicle in place between SPAWAR, Charleston and OPNET. Funding has been determined and released only for the first phase of the delivery order for OPNET's professional services. Future phases may add additional advanced features to the USCENTAF NETCOP system.

Event-triggered and scheduled updates from disparate data sources including HP OpenView, CiscoWorks, Concord, MRTG, NetScout, NetReality, WebTrends, cflowd, Cisco NetFlow, and Government Off The Shelf (GOTS) systems will be fused, analyzed, and graphically updated in the USCENTAF NETCOP system. The NETCOP system will leverage advanced features of OPNET SP Guru, including NetDoctor configuration auditing, dynamic traffic and routing visualization, and simulation.

Bill Strickland, Chief of the Network Engineering Support Team at USCENTAF, stated, "From CENTAF's active, on-going role in Joint operations, we have observed a need to integrate our many disparate network data sources and advanced modeling capabilities, all behind a simple dashboard display. We are thankful to our colleagues at AFCA," the Air Force Communications Agency, "who have understood this need for years, and who acted as a catalyst for us as we refined our requirements."

Marc Cohen, OPNET's Chairman and CEO, added, "The USCENTAF NETCOP requirements for data fusion, modeling, and situational awareness are a perfect fit for us. OPNET's VNE Server and SP Guru products provide a great foundation for our professional services team to build on, and adapt to the unique environment at the Network Operations Security Center. We are using their existing network management infrastructure, which includes products from our alliance partners, and adds a crucial layer of intelligent analysis capabilities. We plan to leverage this pioneering work for USCENTAF with SPAWAR, Charleston, to customize NETCOP systems for other government and commercial entities with similar needs."
