Overview

DesignXpert is a Visio Add-on that appears as a toolbar button group.

Add-on connects to Netformx servers and retrieves three stencils: (Library Browser, Search Library & Blades).

Stencils use Netformx knowledge base to allow user to select, place, configure and validate NT devices.

Toolbar

Stencils

Overview

After you open a Visio drawing. You may start the design process in two

ways: by using Visio VNE (Visio Network Enterprise) stencils or by using one of three Netformx stencils.

The devices you require for your network design are dragged from the stencils into the drawing page, where the project topology is created and/or modified.

OverviewFrom the drawing page, you can:Configure a device and its sub components

manually or by using configuration Wizard. Configured devices can then be validated either manually or automatically.

Generate and view a Bill of Materials sheet which contains a list of the products and subcomponents you have added to your network design, complete with catalog number, vendor, category, quantity and prices.

Change device views in the drawing from front to rear or logical and vice versa.

Features• Library Browser [Device Selection]

– Vendor-Classified

• Search Library [Device Selection]– Vendor: All, Cisco, 3Com– Category: Firewalls, LAN/MAN Switch– Interfaces:

technology (protocol), physical interface, min. no. of ports

– Device Name

– Manual ConfigurationIf you are familiar with configuring devices and know which components to add to

those devices.

– Configuration WizardIf you are not sure which components to put into your device. The Configuration

Wizard allows you to specify the protocol and number of ports needed for your device and lets you review and add components that meet your requirements.

Validation– Auto ValidateAutomatically verify the validity of each component as it is added to a device. If

some added component is not valid or more components are required, auto validate will take you to the Validator page and walk you through the configuration process, addressing all of the components needed for the device.

– Manual Validate Performs a check on your current configuration and determines if it is valid. If not, it

will take you the Validator page to validate your device.

Validation Error Correction move from issue to issue, displaying error messages and a list of components that will fix them by adding, replacing or removing them from device.

QualNet

Introduction

Network simulation is a very efficient and cost-effective way to develop new network technologies. By building virtual networks in a lab environment, researchers can test, optimize, and integrate next generation network technologies at a fraction of the cost of deploying physical testbeds.

The keys to the successful deployment of virtual networks are speed, scalability, accuracy, portability, and extensibility.

QualNet is network modeling software that predicts performance of networks through simulation and emulation.

QualNet

System Requirement

QualNet is supported on Windows 2000 Professional, Windows XP (Home and Professional), and Windows XP Professional x64 Edition. The minimum platform requirements to run QualNet on a Windows system are:

QualNet

Tool Features and Capabilities

• Speed: QualNet can support real-time simulation speed, which enables software in-the-loop, network emulation, hardware-inthe-loop, and human-in-the-loop exercises.

• Scalability: QualNet supports thousands of nodes. Speed and scalability are not mutually exclusive with QualNet. QualNet has achieved real-time simulation for models of 3500 nodes.

• Model Fidelity: QualNet offers highly detailed models of all aspects of networking. This ensures accurate modeling results.

• Portability: QualNet runs on a vast array of platforms, including Linux, Solaris, Windows XP, and Mac OS X operating systems, distributed and cluster parallel architectures, and both 32- and 64-bit computing environments.

• Extensibility: QualNet connects to other hardware & software applications, such as OTB, real networks, and STK, greatly enhancing the value of the network model.

QualNet

Components of QualNet• QualNet Scenario Designera model setup tool that allows users to set

up geographical distribution, physical connections, and the functional parameters of the network nodes. Using intuitive click and drag operations, the user can also define network layer protocols and traffic characteristics down to each node.

• QualNet Analyzerstatistical graphing tool that displays

hundreds of metrics. Users can choose to see pre-designed reports or customize graphs with their own statistics. Real-time statistics are also an option, where users can view metrics as they are generated while a simulation is running. Multiexperiment reports are also available. All graphs are exportable to spreadsheets.

QualNet

Components of QualNet

• QualNet 3D VisualizerThe 3D Visualizer is a QT-based tool for

rich animations of network simulations. Users set up QualNet scenarios in QualNet Scenario Designer and then send the simulation to the 3D Visualizer for animation.

QualNet

Components of QualNet• QualNet Packet TracerQualNet Packet Tracer is a packet-level

visualization tool for viewing the contents of a packet as it goes up and down the network stack. This is a valuable debugging tool.

• QualNet AnimatorQualNet Animator offers in-depth

visualization and analysis. As simulations are running, users can watch traffic flow through the network and view dynamic graphs of critical performance metrics. Users can also assign jobs to run in batch mode on a faster server and view the animated data later.

INTRODUCTION TO THE NETWORK SIMULATOR

COMNET III

Introduction-COMNET IIIHigh-Fidelity Network SimulationCOMNET III accurately predicts LAN, WAN,

and enterprise network performanceenabling users to reduce risk by

experimenting with diverse network alternatives before implementing their plans

eliminates the guesswork of planing and helps avoid costly mistakes

With COMNET III you canPredict end-to-end delays, throughputs,

and utilization of links, buffers, and processors

See peaks and valleys of traffic-not just snapshots and averages

Pinpoint sources of delays and bottlenecks

COMNET ComponentsCircuit-Switched Traffic Module.Satellite and Mobile Module.Distributed Software Module.COMNET Baseliner.COMNET PriceWizard.

Circuit-Switched Traffic Module Circuit-Switched Traffic Module helps you

address the challenges of ensuring smooth circuit-switched traffic flow over your network.

The Circuit-Switched Traffic Module and COMNET III work together to perform capacity planning scenarios for voice requiring bandwidth over a fixed amount of time.

Satellite and Mobile ModuleSatellite and Mobile Module is an add-on

module that enables information about your satellites and other mobile nodes to be incorporated into capacity planning scenarios in COMNET III.

Distributed Software ModuleThe Distributed Software Module for

COMNET III allows software developers to trace state-dependent application behaviors and isolate code problems. It shows you where the application will cause extensive application processing overhead, file contention, or excessive disk access delays.

COMNET BaselinerCOMNET Baseliner extracts topology

information from popular network management systems and traffic information from a variety of network monitoring and RMON tools.

With COMNET BaselinerImport network topology with nodes and

group nodes, or in hierarchical layout. Combine multiple network traffic data files-

which may be collected by different monitoring tools-into a single traffic characterization model.

Preview imported traffic patterns through a bird's-eye view of network activity.

With COMNET BaselinerSee graphical representations of

conversations between nodes; data volume between node pairs is depicted by color-coded lines.

Upload the baseline model into COMNET III or COMNET Predictor to determine the effects of proposed network changes like adding users and applications, or altering equipment, bandwidth or routing.

COMNET PriceWizardCOMNET PriceWizard from CACI products

company is an optional add-on module for the COMNET suite of performance planning tools that lets you determine and experiment with network costs in relation to the associated improvement in network performance.

Use PriceWizard to Compare carrier costs Build least-cost network designs using

tariffs from major carriers Identify cost-effective alternatives to WAN

backbone designs Price frame relay networks
