The leading solution for simulating 10 Gbps networks

Netropy 10G4

Download the Netropy Datasheet:

With a capacity of 80 Gbps, the Netropy 10G4 Network Emulator can simulate four separate 10 Gbps full-duplex links. Each of the four Emulation Engines also offers the ability to filter packets onto 15 separate virtual WAN links with their own bandwidth, latency, and loss conditions, making it easy to simulate a large number of high-speed links using a single emulation device.

The 8 SFP+ ports offer 1/10 Gbps dual rate capability, supporting both 10 Gbps SFP+ and 1 Gbps SFP for easy installation onto any type of 1 or 10 Gbps network.

The Netropy 10G4 is configured and managed through an intuitive, browser-based interface for easy operation, or through a comprehensive command line interface for integration with test automation tools.

Easy to Use

The Netropy 10G4 Network Emulator is quick to install, intuitive to configure, and easy to operate. The Netropy GUI provides the responsiveness of an application with the convenience of a standard web browser.

Multiple Links

The Netropy 10G4 simulates up to 15 separate WAN links through each of four 10 Gbps Emulation Engines, making it easy to simulate large numbers of gigabit or other high-speed links through a single pair of ports. Packets are assigned to individual links by IP source and destination address range (IPv4 or IPv6), VLAN, MAC address, MPLS label, application port number, or any other packet field.

Multiple Emulation Engines

Take advantage of four 10 Gbps Emulation Engines to simulate four 10 Gbps links or large numbers of lower speed links. Each emulation engine is separately managed, making it easy for the device to be shared between users or projects.

Bandwidths up to 10 Gbps

Accurately simulate links from 100 bits per second up to 10 Gbps at full line rate for all packet sizes.

Latency up to 20 sec.

Emulate delay and jitter of 10 seconds or more in each direction, in increments of 0.01 ms, with a constant, normal, exponential, or uniform distribution.

Packet Loss, Corruption, and Outage

Set random, burst, or periodic packet loss, or a bit error rate. Test the effect of data corruption on voice and video applications. Check how applications recover from network outages.

Capture and Replay Live Network Conditions

Record the delay and loss of the live network as they vary second-by-second and replay them through the Netropy emulator in a repeatable test environment.

Replay PCAP Files as Background Traffic

Test how applications run over a congested network without costly traffic generators or a rack full of client machines using Netropy's unique background utilization feature that replays PCAP files as background traffic. Each PCAP stream can replicated to simulate large numbers of users or scaled to adjust the timing and bandwidth usage.

Data Visualization

Graph or download up to 24 hours of throughput and other link statistics to visualize and troubleshoot application performance.


Install each emulation engine as either a bridge or router for easy integration with any test configuration.

SFP+ Interfaces

The Netropy 10G4 has eight dual rate 1/10 Gbps SFP+ ports to connect to any type of 1 Gbps or 10 Gbps Ethernet network.

Automated Testing

Automate testing using the comprehensive command line interface.

User Controls and Security

Use SSL or SSH for secure access to the Netropy interface. Individual users can lock their engine to prevent configuration changes by any other user. Set user passwords on the device or take advantage of an LDAP server.

Unsurpassed Precision

Test with confidence - the high-precision Netropy Emulation Engine ensures accurate and reproducible results.

Self Monitoring

The Netropy Emulation Engine monitors internal processing and buffering resources to guarantee testing validity.

Redundant Power Supply

A modular redundant power supply helps guarantee uninterrupted operation.

Priced Right

Emulate four 10 Gbps networks at a fraction of the cost of competing solutions.

With the ability to simulate up to 15 separate WAN links in each of four 10 Gbps separate Emulation Engines, the Netropy 10G4 has a myriad of uses:

Emulate Four 10 Gbps Links

With an aggregate capacity of 80 Gbps and four pairs of SFP+ ports, the 10G4 can simulate four separate 10 Gbps full-duplex links. Each of the four Emulation Engines is managed separately with its own dedicated pair of ports, making it easy to share the device between separate tests or different users.

Emulate multi-site networks

Model a full enterprise network of regional, branch, and local offices, telecommuters, and partners, all connected to headquarters or centralized datacenter. Each 10 Gbps Emulation Engine can simulate up to 15 different links.

  • View applications as they will be seen by different end users
  • Verify the operation of application servers with concurrent users

Side-by-side benchmarking

Run separate tests side-by-side to:

  • View the effects of different conditions on application responsiveness
  • Compare products from different vendors
  • Tune application settings
  • Analyze the benefits of acceleration and optimization products

Isolate individual applications

Segregate traffic from individual devices and apply impairments to specific applications

Concurrent testing

Complete a matrix of conditions by running multiple tests in parallel
