Precision Testing for Real-World Networks

Problem: Worst-case scenarios for live environments

Many organizations overlook the importance of emulating realistic and worst-case network scenarios in the lab. Failure to test variables such as application performance, effect of delay, and fail-over protection can have serious real-world implications. Without insight into the performance of new hardware, protocols, and applications, the risk of deployment problems rises dramatically. Organizations need a way to reproduce realistic network conditions and behavior to avoid impairments and achieve bottom-line benefits.

Ixia Network Emulator II

Solution: Real-world networks in the lab

Ixia's Network Emulator II is a precision test instrument for 10GE, 1GE, and 100MbE Ethernet impairment that enables IT to accurately emulate network conditions that occur over live production LAN/WAN networks. With Ixia’s next-generation network emulation, organizations can validate and test the performance of new hardware, protocols, and applications in a controlled lab environment.

  • How will applications perform when distributed across data centers?
  • What will be the precise effects of delay on application and network performance?
  • How will data center backup perform in a real-life environment?

Ixia Network Emulator II answers all these questions to determine real-world network performance without real-world repercussions.

For critical operational deployments, Network Emulator II can be combined with Bypass switches that allow Network Emulator II to be switched in and out of operational networks swiftly and easily with minimal disruption to live network traffic.
