How to Emulate Realistic Network Traffic

+ IxNetwork

Controlled Real-World Network Conditions

Engineers can validate network devices and applications by recreating realistic traffic and network conditions in a controlled lab environment. The test starts by generating representative network traffic and establishing repeatable traffic flows between test endpoints and the device or system under test. Engineers then introduce conditions that reflect production networks, including delay, packet loss, traffic shaping, and other network impairments. By controlling these variables, the test environment can reproduce normal operating conditions as well as more demanding scenarios without relying on a live production network.

During the test, engineers vary traffic levels and impairment conditions while monitoring how the device, protocol, or application responds. They can measure traffic forwarding behavior, packet loss, throughput, latency, and other relevant performance indicators as network conditions change. Engineers can repeat the same test configurations to compare software revisions, hardware configurations, or network settings under consistent conditions. This approach combines realistic network traffic, network emulation, and repeatable performance testing so engineers can observe how the system behaves across a defined range of real-world network conditions.

Real-World Network Validation Solution

Recreate realistic network traffic and controlled network conditions by combining traffic generation, protocol emulation, and repeatable performance measurements. Keysight’s IxNetwork generates realistic Layer 2 and Layer 3 traffic flows and emulates network protocols and topologies so engineers can exercise network devices under scalable, repeatable workloads. Engineers can configure traffic patterns, vary offered load, and monitor forwarding behavior and performance as test conditions change. For tests that require real-world network impairments, engineers can introduce conditions such as delay, packet loss, and traffic shaping into the test path. This combination lets teams reproduce both normal and adverse network conditions in a controlled lab environment while measuring how the system responds. IxNetwork provides traffic analysis and performance visibility that help engineers evaluate network behavior across changing traffic and topology conditions.
