FAQ

What does a network emulator do?

A network emulator replicates real-world network conditions (e.g., bandwidth limitations, latency, jitter, and packet loss) in a controlled lab environment. This allows organizations to test and evaluate how applications and devices perform under various network scenarios to ensure reliability and optimal user experience (before and after deployment).

What is the difference between a network simulator and a network emulator?

A network simulator models the behavior of a network by using mathematical formulas to predict performance. However, simulators don’t typically use actual hardware or real data traffic.

A network emulator uses real data packets and hardware to mimic the behavior of existing networks. This provides a more accurate and practical assessment of how applications will perform under specific network conditions.

What is the maximum aggregate throughput of Netropy’s Network Emulator?

The maximum aggregate throughput varies by model:

  • Netropy N61: Up to 2 Gbps.
  • Netropy N91: Up to 8 Gbps.
  • Netropy 10G1: Up to 20 Gbps.
  • Netropy 10G2: Up to 40 Gbps.
  • Netropy 10G4: Up to 80 Gbps.
  • Netropy 100G: Up to 150 Gbps.

What kind of networks can I emulate with Netropy?

Netropy can emulate a wide variety of networks, including:

  • Wi-Fi: To assess performance over wireless connections.
  • Satellite: To simulate high-latency, low-bandwidth conditions, including specific weather events.
  • SD-WAN: To test software-defined wide-area networks.
  • Ethernet and MPLS: To replicate traditional wired networks.
  • 5G and 4G LTE: To test mobile applications.

What’s the difference between the hardware-based Netropy and its virtual/cloud counterparts (NetropyVE and NetropyCE)?

  • Netropy (Hardware-Based) provides dedicated hardware appliances for high-performance, precise network emulation. Hardware is ideal for on-premise testing environments.
  • NetropyVE (Virtual Edition) is a virtualized version of the hardware emulator that runs on standard servers or virtual machines. This offers flexibility for lab environments without the need for physical hardware.
  • NetropyCE (Cloud Edition) is designed for cloud-based testing, allowing users to emulate network conditions within cloud infrastructures. This facilitates the testing of cloud-native applications.

Each version caters to different testing needs and environments, providing scalable solutions for various deployment scenarios.
