New modules diversify use of network simulator for engineers and planners

The modules can model traffic over
satellite and circuit-switching networks.

CACI Products Co. has introduced a suite of new modules for its flagship Comnet III
network simulator. The modules can model traffic over satellite and circuit-switched
networks, as well as predict application behavior.

The Satellite and Mobile Module is targeted to the government market, said Chris
LeBaron, vice president of strategic marketing for CACI Products of La Jolla, Calif.

Comnet III, a high-fidelity network simulator introduced in 1994, does fine-grained
modeling for engineers and network planners. The new modules will diversify its uses,
LeBaron said.

The Satellite and Mobile Module incorporates the Satellite Tool Kit from Analytical
Graphics Inc. of Malvern, Pa., which models things as diverse as satellite orbits and
motions of mobile network nodes.

The module predicts throughput and performance for wireless network segments,
identifying bottlenecks and determining the number of channels needed on a ground station
or satellite.

The Circuit-Switched Traffic Module has traffic source objects for modeling voice,

fax and video transmissions. It optimizes planning for dedicated circuits to comply
with service-level agreements.

The Application Profiler predicts the performance of beta applications across an
enterprise network without actually running them. It creates a performance profile from a
LAN test segment, then uses modeling data from Comnet III to generate predictions.

The Profiler also can answer managers’ questions about running new applications on
different network topologies.

All three modules are available now, starting at $15,000.
