Deliver robust, high quality apps

Software development labs are too fast and too clean unlike real-world networks. KMAX recreates slow, congested and less-than-reliable services encountered by apps and devices in the real world. See how your product will perform in realistic network conditions.

Find problems before your users do

Proactively identify and remove product defects prior to release. Poor app performance erodes user confidence and can damage your reputation. Save face, save money and assure success by emulating real-world network conditions in your test lab with KMAX.

Intuitive, Responsive, Graphical User Interface

Use the KMAX Network Simulator from any web browser on a tablet or desktop. The Wizard guides you through set up and operation.

  • Point & click the scenario closest to your production environment
  • Fine tune & adjust network impairment parameters
  • Create your own scenario
  • Specify time-varying impairments to your emulation
  • Easily view network emulation statistics in customizable tables & graphs

APiJET's Success

APiJET helps airlines improve efficiency by turning planes into Smart Aircraft. To do this, APiJET needs to recreate the communications environment that their clients' aircraft experience during flight.

  • KMAX can accurately emulate the satellite link used by Icelandair, an APiJET customer
  • Using KMAX allowed APiJET to avoid having to install an extremely costly and unnecessary dedicated communications infrastructure just for testing

Add Time-Varying Impairments to Your Emulation

Real world networks change their behavior over time. And so should your network emulation scenario.

  • Create a network emulation that varies the impairment parameters over any time period
  • Specify a time-varying expression for any metric, using equations, piecewise curves, or shaped pulses

Scalability & Flexibility at Your Finger Tips

KMAX is available in several hardware and software configurations. In addition, the KMAX web server exposes a REST API that provides remote control over all aspects of KMAX including the impairment engine and statistics gathering. Insert the KMAX network simulator directly into your testing pipeline using our reference templates.

  • Plug KMAX into your existing diagnostic tools for custom statistics collection & display
  • Automate KMAX reconfiguration to run different configurations for different tests for overnight testing
  • Add a fully custom user interface by using any scripting language with an HTTP client
Product Brief

Simulate Network Latency

KMAX offers many individual parameters for precisely controlling a network simulation. These include: packet drop, packet delay/latency, packet jitter, packet duplication, packet re-ordering, rate limitation, packet corruption. Of these, network latency is of most concern:

  • Simulate network latency / delay via a pre-defined scenario, OR
  • Precisely customize network latency / delay to meet your requirements.
  • Add jitter, reordering, resequencing, queue management, etc.
  • Test any particular network impairment, precisely.

KMAX is a Network Simulator

KMAX is a network simulator from the perspective that it uses mathematical models to simulate certain kinds of problematic network conditions.

Academic researchers observe and record large, operational network data sets. From the data sets, the researchers analyze the frequency, duration, and nature of various network anomalies. Based on this information, one can forecast the probability (likelihood of occurrence) of specific network anomalies.

KMAX uses this analysis in scenarios to replicate real-world phenomenon. By utilizing waveforms, KMAX can simulate the network behavior over time, precisely replicating the onset, the duration, and drop off of the network anomaly.

KMAX is a Network Emulator

KMAX is a network emulator because it imitates the function of another system. It accepts the same packets, transforms them, and send them on its way, in the same way as the system it is emulating. The emulated system could be a low earth orbit satellite or the wireless to 5G handoff between a mobile app and the cloud. KMAX emulates a wide range of network communications systems and emulates them under a wide range of conditions, both favorable and unfavorable.

Actual network traffic and network conversations can be recorded and replayed with fidelity to the problematic traffic conditions. Or KMAX can simply replace the original communications network entity by emulating its performance in the lab.
