Scalable Networks Delivers Industry's First Real-time Simulator for Network Management, May 24, 2002.
LOS ANGELES--(BUSINESS WIRE)--May 24, 2002--Scalable Network Technologies (SNT), a Los Angeles-based company that develops network simulation software, is introducing its new QualNet software platform at SUPERCOMM 2002 (booth 10811). QualNet is a highly detailed modeling suite for the design of networking devices and optimization of networks in complex topologies. From Voice over IP and Quality of Service technologies to cellular, satellite and mobile ad-hoc networks, QualNet can simulate all kinds of networks.
QualNet brings new levels of productivity and accuracy to network modeling projects. The purpose of network simulation is to predict how different devices and configurations affect network performance in terms of throughput, delay, bandwidth efficiency, etc. Simulations that produce real-time results for detailed network models are highly desirable. With QualNet, high fidelity real-time results are attainable for very large networks.
QualNet's five modules help modelers quickly build and run simulations. The five modules are:
- QualNet Animator for model set-up. Modelers build topologies and see network simulation in action.
- QualNet Designer for fast code development. Users produce custom code using the Finite State Machine tool to represent code logic.
- QualNet Simulator for running the model. QualNet's kernel scales up to accommodate networks of more than 10,000 nodes.
- QualNet Tracer for debugging. Modelers watch individual packets move up and down the stack to validate code and identify bottlenecks.
- QualNet Analyzer for reporting. Extensive statistics help easily isolate critical factors in network performance.
In addition to the five modules, QualNet has a large protocol model library for wired and wireless networks.
According to John Powers, Principal Software Engineer in the Visualization and Simulation Lab at Raytheon in Plano, Texas, the five modules make up a software package that's reliable and stable, yet fast. "Real-time simulation was our number one concern in choosing a simulator, and QualNet was very fast on our Linux PC," said Powers. "Our project's ultimate objective was interactive real-time modeling of thousands of entities.
"The first step, though, was building a prototype in QualNet with just a few dozen entities," said Powers. "Our prototype has successfully passed notional messages between nodes in real-time. This prototype model will evolve into the model for person-to-person communications, a very important piece of our integrated battle simulation. Everything depends on how people react when communications are distorted, weak or impossible due to terrain and ad-hoc routing. We chose QualNet because it is the most promising tool to realistically simulate battlefield communications in real-time."
"The five modules provide full extensibility, fidelity, statistics and speed for high-value results," said Rajive Bagrodia, SNT's President and CEO. "QualNet removes the guesswork out of designing and deploying networking technologies in a vast number of applications --in both public and enterprise networks and wired and wireless arenas," continued Bagrodia. "QualNet provides the first real-time network simulation platform that performs essential design phase validation and scalability tests, and it is the only simulator with the scalability to model real network behavior for 10,000-node networks."
