Emulate the Real World

The Maxwell G network emulator creates the same real-world conditions that affect production networks, in your lab or on your desktop, so you can visualize and understand the effects.

Emulate the Real World

Use Maxwell G to classify traffic into concurrent, multiple flows for realistic emulations.  Filter out LAN traffic not present on the WAN. For even greater fidelity,  apply different impairments (drop, delay, jitter, duplication, reorder, etc.)  on each flow and in each direction!

Optimize Application Performance using Maxwell G Network Emulator 

Emulate your network with new applications, adverse network conditions, Lossy networks (LLNs), and anything else you can think of with Maxwell G.

The Maxwell G network emulator is well suited to training and learning environments, demonstrations and trade shows, and testing, validation and troubleshooting.

Limiting bandwidth to see how your new application will perform on slower network connections, particularly wireless, is one of the most popular applications for Maxwell G.  

Learn how a product will perform in mobile, cloud, Lossy, and WAN networks.  Induce the conditions that cause network congestion, slow links, time outs, and many other adverse network conditions.   See the effects on the device or application to test, diagnose, and remediate product performance, solve network problems, and learn the limits of device and application performance.

Simple Setup and Web Interface

Attach Maxwell G at any point in the network without any special configuration.  From a web interface, point and click to introduce bandwidth limited conditions or network impairments.  Then observe the behavior on applications and devices.  In this way, you can quickly and efficiently determine how resilient your product is to the conditions that occur on real-world networks.

Changes occur when submitted - there is no need to restart.

Settings may be saved onto the user's own computer and restored when needed.

Scripting and Autonomous Operation

The current settings may be saved to , and they will be automatically restored when Maxwell G is powered up.  This facilitates field operation where it would be inconvenient to have a keyboard, mouse, monitor.

Maxwell G may be scripted from another computer using a spreadsheet of a Python program.

Packet Classification Filters

  • Maxwell G is able to classify packets on the basis of many IP, UDP, and TCP header fields
  • Traffic may be classified into as many as five bands in each direction (ten bands total)
  • Different impairments may be imposed onto each band
  • Multiple filters may be simultaneously active
  • Users may create their own filters
  • Filter changes occur when submitted on the fly, no need to restart
Filters, Filter Map, Filter Sequence

Multiple Bands

With Maxwell G, the user may impose several kinds of impairments on up to five different traffic flows in each direction (ten bands total).

Bands, Bands with bypass on

Impairment changes occur when submitted on the fly, no need to restart

To support A-B comparison testing a bypass-mode allows all impairments to be turned off and on using a mouse click.
