WaveTest - Designed for equipment manufacturers to accurately analyze the performance of their WLAN infrastructure products, as well as for carriers and enterprise users that want to make the right choice when selecting WLAN equipment for deployment in their networks.
REPEATABILITY - Sophisticated traffic scheduling emulates real-world scenarios of clients contending for the shared
medium
- Regression testing using industry accepted test scripting languages
- WLAN client emulation independent of off-the-shelf MAC and radio constraints guarantees
repeatable test sequences
AUTOMATION - VeriWave Command Library enables test automation using Tcl, Perl and Python
- Test setting and results configurations are interchangeable between VeriWave’s automated test
suites and user scripts
Testing a large scale Wireless LAN has historically been an enormous challenge. With the WaveTest 90 / 20, network testing is brought to a new scale:
Thousands of STAs connecting to a WLAN, utilizing hundreds of Access Points – all competing for the same radio spectrum. True emulation of this
environment is now possible:
- The WaveBlade traffic scheduler offers fully interleaved traffic flows,
emulating real mobile clients contending for the shared medium
- The traffic scheduler dynamically adjusts offered load to approximate
intended load with load resolution of better than 0.5%
- Client contention can be precisely emulated, guaranteeing real-world
behavior in every test iteration
- Client behavior is indiviadually controlled providing accurate control
of 802.11, 802.3, and IP characteristics, including power, medium
access control, authentication and encryption, frame size and rate
- Each WaveBladeTM traffic generator/performance analyzer emulates up to 500 WLAN or 1,000 Ethernet clients across single or multiple subnets
- Each WaveTest 90 supports up to 9 WaveBlades with a combined capacity of up to 4,500 individual WLAN clients (STAs)
- Unprecedented network scale can be achieved by daisy-chaining up to six WaveTest 90 chassis for a total of 27,000 emulated clients
- Generate and analyze traffic between WLAN clients and Ethernet clients/servers, or mobile WLAN clients
- Gigabit Ethernet traffic generation and analysis at full wire-speed - Multiple traffic flows per client are supported, with each flow offering
traffic at Layers 2, 3 and 4 - Real-time port statistics, per flow statistics, packet filters, triggers and
capture capabilities for precise analysis - Built-in client mobility allows precise roaming of each and every client
between any Access Points, at pre-determined times or power settings
Large Scale Testing
Real-World WLAN Client Emulation
Typical setup supports testing of tens of Access Points and multiple WLAN switches
Scheduler interleaves traffic flows contending for the shared medium
Responding to the unique demands of developers, QA test departments, pre-deployment labs, and competitive marketing labs, the WaveTest offers three fully-integrated use-models:
- Roam hundreds of clients; individual client roaming behavior is
controlled by the user allowing for 100% repeatability of tests
- Client initiated roaming as well as switch-initiated roaming is
supported
- Utilize VeriWave’s automated roaming application or user-defined
scripts
- Scalability test:
– Measure throughput, latency, and frame loss while clients
roam
– Measure roaming delay per client and per client-group
Acceptance of WLANs in corporate networks for mission critical applications is dependent on the flawless performance and security of these networks. WaveTest addresses this need with a set of purpose built test suites:
- Load test:
– Measure the maximum client load that the System Under Test
can handle without dropping any clients
– Measure the effects on roam times as the number of roaming
clients increases
- Test the performance of the System Under Test to handle a
multitude of security profiles used by the clients
- WaveManagerTM – this user interface offers comprehensive and interactive control of multiple chassis and test ports – mobile-client emulation, Ethernet client emulation, traffic generation and analysis, all from a single, easy-to-use dashboard
- VCLTM (VeriWave Command Library) – Programmatic control, test configuration, statistics, and reporting functions are supported via this common library that is accessible via Tcl, Perl, and Python
- Automated tests address specific applications that require automation and regression, such as roaming, performance benchmarking, VoIP over WLAN, and security
- Configuration data, test control, and results are all seamlessly transferable between all use models. VCL command scripts can be generated automatically in Tcl, Perl, or Python from existing hardware or user configuration
- Test results are collected and displayed using an extensive set of predefined counters, user-defined counters, triggers and filters, as well as a 100 MB capture buffer per WaveBlade
WaveManager Graphical user-interface – provides complete control of WaveTest chassis and WaveBlade cards
WLAN Roaming Automated roaming test suite
VCL Library SDK Provides access, configuration and control of WaveTest chassis and WaveBlades, allowing users to execute custom scripts; supports Tcl, Perl, and Python
