Abstract

Today’s enterprises, service providers, and government agencies are being tasked to effectively monitor the performance and security of their networks. Fortunately, sophisticated tools are available for this purpose; however these tools are expensive and often in short supply in large organizations where assets are shared.

To meet this need, the nGenius® 3900 series packet flow switch from NetScout® is a modular, chassis-based switch architecture, that supports high-density1GbE, 10GbE, and 40GbE. The nGenius 3900 series packet flow switch offers up to 48 ports of packet flow switching in a single blade system, 144 ports in a 3-blade system, and 576 ports in a 12-slot system.

NetScout commissioned Tolly to evaluate the scalability, functionality, and ease of management of the nGenius 3900 series packet flow switch and the nGenius PFS management software. The nGenius 3900 series packet flow switch provides ultra-low latency in a highly flexible, scalable Layer 1-4 platform, designed to improve network and application performance monitoring, network security, and forensic recording. The nGenius packet flow switch delivers consistently low latency across the range of topologies and scenarios tested.
