Solutions to Challenging Problems

 

Commercial enterprises, educational institutions and governmental organizations around the world all depend on reliable, effective networks to deliver business-critical, mission-critical communications and information. Combining constantly evolving technology with the accelerating move to highly mobile widely distributed users presents systems architects and network managers with a vast array of challenging problems.

By creating high-fidelity virtual models of both existing and proposed networks, and then quickly evaluating a wide range of potential operating scenarios, organizations can:

  • optimize the network, systems and applications performance and the physical structure
  • identify issues, bottlenecks and failure modes before they impact users
  • design, validate and deploy expansions more rapidly
  • quantify potential business or mission impacts due to cyber attacks and the resulting network disruptions
  • save money by not over building or having to react to unexpected issues
  • lower risks by actively understanding technical choices and business compromises

Pinellas County Saves $9M
First Responder Network Analysis
Pinellas County, FL was evaluating proposals to replace an aging radio communications network used by their emergency response personnel with a new advanced 802.16-based mesh system that utilized the 4.9 and 5.8 GHz spectrum.

Six different vendors were bidding on the contract, and all had submitted detailed proposals with sophisticated network designs. All of the proposals came in over the allocated budget.

Based on QualNet simulations of the new mesh radio technology, a network consisting of just over half of the fixed and mobile equipment originally proposed by the lowest bidder was sufficient to meet the needs of the County.

USSTRATCOM Cyber Experiment
Cyber Situational Awareness Exercises
A US Strategic Command test and experimentation team was chartered to explore how the degree of cyberspace situational awareness integration affects the Joint Force Commander’s ability to make timely and informed C2 decisions of forces in all domains.

Incorporating an EXata virtual network model, the experiments were successfully executed over a series of events throughout a week, hosting over 40 players across four distributed locations in Maryland, Virginia and the United Kingdom.

US Army Lowers Testing Costs by 57%
Airborne Router Evaluation and Problem Identification
A global defense contractor was developing an implementation of the Multi-Role Tactical Common Data Link (MR-TCDL) specification for an airborne router application.

The customer (the US Army) wanted thorough validation of the MR-TCDL implementation, but also wanted to minimize the expense of live flight tests.  The contract allowed for a maximum of seven flight test days.

Leveraging an EXata simulation model with system-in-the-loop emulation, the entire validation exercise was completed successfully in only three live flight test days.

NETCOM Evaluates Deployment Strategies
Enterprise Network Application Services Optimization
US Army Network Enterprise Technology Command is continuously exploring how to deliver IT services in the most effective manner to their community of users. A series of investigative projects were authorized that were estimated to cost approximately $800K and take six months to accomplish if a physical test environment was utilized.

Using network simulation, engineers were able to identify optimal network configurations, and the overall simulation exercise took less than 2 months and cost less than $300K.
