The NE-ONE Professional Network Emulator has been designed with ease-of-use in mind. Whether you are an Application Developer, Software Tester, Network Engineer or a Systems Architect, it will enable you to quickly and easily recreate a wide range of realistic networks (LAN, WAN, Internet (Cloud), Wi-Fi, (A)DSL, Mobile, Satellite, etc.) in order to test application performance.

Intuitive & Intelligent Pictorial Web GUI

At the heart of NE-ONE’s ease-of-use is its intelligent user interface which is designed to make setting up and running a real-world test network achievable in a few minutes. NE-ONE eliminates the need to spend hours learning complex tools with cumbersome tabular interfaces and scripting. Instead, use your preferred browser (no plug-in required) and select the required values using pre-populated network parameters from drop-down menus.

Auto-Configuration – Removing the Guess Work

NE-ONE has a range of Auto-Configuration capabilities to save you time and remove the guess work or need to be a network specialist when setting up your test environment.

Geolocation Network Latency Calculator

Imagine you need to emulate a link from New York to London but you’re unsure of what latency to use. NE-ONE comes with a catalogue of over 42,000 locations, so simply choose the required start and end point locations and NE-ONE will calculate and insert the base latency for you.

Predefined Link Types & Associated Properties

You know that you need to test using a 4G network, a VSAT link or some other type of network but how do you go about creating a range of real-world network experiences? Drawing on our expertise, we have populated the NE-ONE with representative latency, loss, bandwidth and other network characteristics, to reflect Excellent, Good, Average and Poor link qualities typically encountered in real networks. However, for more experienced users or where specific conditions need to be configured, NE-ONE has a comprehensive library of impairment options.

Scenarios Library

The NE-ONE comes with a set of pre-written network scenarios. These are available locally to be loaded and run. Scenarios include: Coffee Shop Average Wifi to Outside Average 3G; Ship sails away from Land; Underground Station Average WiFi to next Underground Station Average WiFi and More.

Multiple Concurrent Links (Paths)

NE-ONE’s multi-link feature can simultaneously emulate up to 20 different network links (paths) between the end points, each link with its own characteristics, helping to save valuable testing time. For example, you can set up three links for 2G, 3G, 4G mobile networks and concurrently compare their application performance. NE-ONE’s Link Qualification Criteria enables you to define what IP Addresses, Applications or VLANs use which link.

Dual Hop / Last Mile Emulation

Frequently real networks comprise more than a single uniform segment i.e. Dual Hop. There is often another significant portion of the network chain, including a “last mile” hop. For example a data center to a branch office could include a WAN and Wi-Fi in the data path. NE-ONE’s Dual Hop feature allows you to pictorially configure these hops quickly and easily to provide an overall experience to test with.

Real-World Network Conditions

When used in Advanced Mode, NE-ONE provides access to more than 50 network impairments that provide accurate, realistic, repeatable and controllable network conditions. Each of these are further customizable to enhance the realism of your test setup. Please refer to the “NE-ONE Emulator Impairment Data Sheet” for more information.

Free Flowing Traffic

The NE-ONE allows network traffic to pass through, unimpaired, when no emulation is running.

Graphs & Statistics

NE-ONE’s built-in graphing feature allows you to view key network performance metrics in the GUI. You can also export these statistics for use in other analytical tools enabling you to visualize and understand how the applications are being affected by changes in the network.

Command Line Interface (CLI) & API

Easily integrate testing over real-world network conditions into your existing test cycle by using NE-ONE’s CLI or API to automate changing network conditions from your functional and/or performance test tools or test scripts. This significantly enhances test processes to identify network deployment risk with minimal impact on test time and resources.


Multiple simultaneous users can access the NE-ONE enabling effective collaboration on configurations, graphs and test results.

Packet Capture

Full packet capture in pcap format provides pervasive application visibility, analysis and troubleshooting for use with other tools including Wireshark.

NE ONE Network Scenario Builder

Adopting an intuitive “Drag & Drop” approach, the Network Scenario Builder allows you to rapidly create a chronological network experience by simply combining multiple network types and conditions running over a graphically represented timeline. The realism of these test scenarios is further enhanced by selecting from intelligent built-in transitions between each network segment to fully represent what happens in the real world.

NE-ONE’s Scenario Builder comes with a library of example network experiences such as variable mobile network experienced on various journeys and network type changes such as mobile to WiFi. These examples include LAN, WAN, Internet and Satellite network scenarios which provide a realistic representation of what can happen to the network conditions when a user’s location and/or network conditions alter.
