WaveDynamix™

WaveDynamix - is an application that works with the WaveTest system to help development and test engineers at network equipment manufacturers and service providers quickly create a broad range of functional and scalability tests for 802.11 and Ethernet devices. The base 802.11 and 802.11n standards, at over 1500 pages in combined length, encompass a great deal of complexity, demanding that any quality product must be thoroughly tested to verify performance and stability. WaveDynamix™ greatly simplifies this process by allowing functional components to be easily tested in isolation and then integrated and tested as part of the complete system.

Benefits

Exploratory Testing: It is often clear that a device under test is not producing the expected results, but the cause of the unexpected behavior can be difficult to isolate. Some experimentation is necessary to identify the source of the problem before a fix can be created or a more formal regression suite can be introduced. WaveDynamix provides customers with a flexible and efficient tool to trial different test conditions and examine responses both in the test equipment and in their device.
Over-time Results: Many problems in wireless networks can be traced to the stateful interaction between clients and servers, and show up as system instabilities. WaveDynamix provides the user the ability to create these dynamic interactions and to view the device’s response over time. The network’s ability to gracefully handle these various conditions is critical to delivering a high quality system.
Functional Testing: The granular control of WaveDynamix makes it very easy to support a variety of functional and negative testing. The interactive control of WaveDynamix allows the user to halt the state changes in the test bed and to verify that the DUT is in the proper state during each step of the test. In addition to identifying functional failures, this capability of WaveDynamix also facilitates rapid identification of the cause of any functional failures.
802.11n Testing: For 802.11n networks to approach the advertised rates of the technology, it is necessary to understand how well each acceleration mechanism works independently and as part of a standard configuration. WaveDynamix enables users to quickly assess the static and dynamic performance of 802.11n networks with a variety of client types, traffic flows, QoS configurations, and physical layer conditions in all stages of product development.

Key Features

Decoupled Management and Data Planes: WaveDynamix is the first 802.11 test tool that allows the tester to control the management plane and the data plane independently providing unprecedented control. This capability can be particularly useful for hardware engineers who can send and receive frames without first having to form an association between a client and an access point.
Highly Interactive Interface: Networks are highly dynamic and intelligently respond to changes in the network conditions. Testers can easily change network conditions on the fly, by adding new clients or changing flow rates, and immediately view the results in real-time charts and graphs.
Generate Normal and Custom Traffic: Users can generate either fully compliant UDP or stateful TCP traffic, or create fully customized packets independently or concurrently. For developers, the custom frame capability can be very useful to test content-specific features such as filters and rogue AP detection. Custom frames can also be used to generate DoS attacks on a network infrastructure while simultaneously viewing the forwarding behavior of compliant traffic.
Integrated Troubleshooting: A wealth of diagnostic information and troubleshooting tools are available to facilitate rapid problem identification and isolation. An integrated capture/decode capability runs on every port during the test session and allows users to view physical and logical layer information in the protocol decodes using the VeriWave radio tap header whenever there is an unexpected event.
