 Test Lab Solutions

Overview

 Doing More with Less

Under pressure to do more with less, test lab professionals are focused on getting better utilization out of test tools, consolidating global resources, and leveraging proven technology across more configurations.

Complexity of Test Labs Present Costly Problem

The rapidly changing nature of today’s test labs presents users with unique challenges. The complexity and variety of test configurations often lead to longer than necessary test cycles. At the same time, there is an increased pressure to improve the efficiency of lab equipment in order to keep capital expenditures from sky rocketing.

Improve Network and Application Test Lab Efficiency, Speed, and Performance

NetScout's Test Optimization solution helps users improve their network and application test lab efficiency, speed, and performance. Our TestStream Management Software and Packet Flow Switch family deliver highly scalable and intelligent solutions offering unique layer 1-4 functionality in a single platform. We enable you to increase the utilization of existing tools and devices under test, reduce the time required to set up and test, and decrease the need for new tools, improving overall lab performance.

    

 Functions of an Optimized Solution

 

 Functions of an Optimized Test solution from NetScout include:

Packet Generation: Flexible packet generation across 1/10/40/100G interfaces provides initial testing or  background load for complex test scenarios.
 Impairment   Impairment: Simulate real world network conditions in a test lab environment. Test streams can be manipulated to introduce realistic network anomalies that are not otherwise available without additional tools.
 Traffic Statistics   Traffic Statistics: Collecting statistics on individual interfaces provides a third-party view to corroborate metrics shown by test tools and DUTs. Statistics are available in real time and collected for post-test analysis.
 Filtering Function   Filtering: Based on user selectable criteria, test streams are routed at a packet level based on L2-4 header fields. Packets can be routed to specific interfaces or dropped to simulate error conditions.
 Aggregation Function   Aggregation: Creates a single test stream by combining multiple input sources. Combining test streams from application-specific test tools presents a more realistic scenario to the DUT.
 Rate Conversion Function   Rate Conversion: Enables you to connect test tools to DUTs regardless of the interface speed. This functionality increases interoperability and greatly extends the lifespan and utilization of 1/10/40/100G test tools.
 Replication Function   Replication: Allows users to create multiple test streams from a single input source. These replicated streams can be directed to multiple interfaces to increase load on one or more DUTs.
 Tap Function   TAP: Passive tapping helps test engineers diagnose problems that occur during test execution. By delivering real-time packet streams to analysis tools, users can analyze and identify problem conditions without disrupting the test traffic flow.
 Switch Function   Switch: Physical layer switching automates network topology moves, adds, and changes. Connected ports pass unaltered traffic at line rate with no protocol dependencies, optimizing lab operation in a number of ways, including test tool sharing and remote control.
