Testing Reasons
• The Internet is made up of various components, such as routers, switches,
hubs, firewalls, etc.
• Many different equipment manufacturers as well as service providers are
needed in order to support the Internet.
• These manufacturers and providers need the tools to test, simulate,
analyze, troubleshoot, develop, and certify network infrastructure, from
initial design to ongoing testing of the final network.

• The previous section identified the RFCs associated with
particular test environments.
• The previous section also presented SmartBits products you
could use to test these environments.

SmartBits GUI Applications
• Most SmartBits applications include a graphical user
interface (GUI).
• Many test developers find creating tests with a GUI ideal
because it is easy to use and enables them to begin testing
quickly, sometimes within minutes of installation.
• GUI interfaces are intended to be highly intuitive and to guide
the user through the test process.
• Ease of use is a primary consideration.

What are my requirements?
• To help identify the SmartBits GUI application for your testing
needs, you first must identify your testing requirements:

What is my priority, ease of use or testing complexity?

What kind of results do I expect, graph, HTML, raw data?

What is more important, control or automation?

Am I planning to migrate to script based tests in the future?

SmartBits Test Control
• No matter what application you use to configure the
SmartBits chassis and ports (SmartWindow, SmartFlow, AST
II etc.) the end result is that they run the test based on the
configuration.
• Set up the hardware in the configuration needed for the test.
SmartBits
• Update the hardware with this packet image.
Software is • Instruct the hardware how many packets to transmit, how they are
responsible
to be transmitted, etc.
to:
• Tell the hardware to start and stop transmitting.
• Retrieve data and process results

Control verses Automation
• Having control over an application allows you to:

Create custom traffic

Create custom execution of the test

Gather custom results
• Having an application provide more automation allows you to:

Have plug and play testing

Provide RFC specific testing

Run specific types of test designed by the application

Generate scripts from GUI screen configurations
• The more control you have, the more customization you can perform.
• The more automation you have, the more plug and play the application.

Traditional vs. SmartMetrics Modes
• SmartBits Cards/Modules are classified as Traditional,
SmartMetrics, and even TeraMetrics (discussed later).
• Depending on the type of Card/Module you are using, it will
have some or most of these capabilities.
• Depending on the type of SmartBits application you want to
run, you may use some or most of these capabilities. (Not all

WebSuite/Firewall Specific Features
• Supports testing using NAT/PAT mode.
• Supports port pair and backbone traffic distribution
patterns (with exclusive client/server pairs).
• HTTP traffic type (Goodput):

Supports returned object size per URI.

Uses real TCP sessions to gauge application throughput.

The TCP stack implementation includes adaptive retransmission,
slow start, congestion avoidance, and delayed acknowledgement.

You can define the maximum segment size (MSS), window size,
retry time, and retry count of TCP.

You can also assign a type of service (TOS) precedence level to
the traffic.

Real Proxy Invokes the Real® Launcher® to test Real streaming servers.
Verification enables you to validate test configurations.
Sample Tests Provides default tests to assist first time users.
Test File Uploading Allows adding customized associated test files to the User Profile.
URL List Recorder Employs a proxy recorder to expedite creating complex URL Lists.
Cookie Preloading and Dumping allows recording all the cookies used in a test, then
logging those cookies in a format that can later be pre-loaded in a subsequent test.
• Caching Proxy Simulates network traffic managed by a proxy server, which responds
to a URL request itself instead of directly accessing the destination server.
