Abstract

Today’s enterprises, service providers, and government agencies are being tasked to improve the efficiency of their network, application, and security test labs. Sophisticated tools are required for various test scenarios; however these tools are expensive and often in short supply in large organizations where assets are shared.

To help optimize tools and infrastructure, the nGenius® 3900 Series Packet Flow Switch from NETSCOUT® is a modular, chassis-based switch architecture, that supports high-density 1GbE, 10GbE, and 40GbE. NETSCOUT's Test Optimization product line provides specialized hardware and software to meet requirements that are unique to test labs. NETSCOUT S-Blade Pro is a low latency blade that works in conjunction with NETSCOUT TestStream Management Software to provide an easy-to-use, multi-function environment for Layer 1 switching. Additionally, S-Blade Pro provides bandwidth-based utilization statistics for all ports.

NETSCOUT commissioned Tolly to evaluate the Layer 1 functionality of the NETSCOUT S-Blade Pro in both 10GbE and 40GbE network topologies evaluating the latency across a full range of RFC 2544 frame sizes as well as with jumbo frames and utilization statistics. The S-Blade Pro delivered ultralow latency at every frame size tested.
