NetFlow and other network metadata generation methods are a simple, effective way to increase visibility into traffic flows and usage patterns across systems. However the processor and memory load of enabling NetFlow and metadata generation can cause service degradation and affect their ability to pass traffic without introducing latency and packet drops. This whitepaper examines how The Gigamon Visibility Fabric establishes a scalable framework to deliver pervasive flow-level visibility across enterprises, data centers, and service provider environments to help users accurately design, engineer, optimize, and manage their network infrastructure.
