Conclusion
Cisco NGA redefines network visibility and establishes a new standard for a high-performance, cost-effective
solution for flow visibility. The product introduces a cross-device approach to flow visibility, facilitating hop-by-hop
analysis of flows across multiple network segments. Cisco NGA delivers 100 percent accuracy with no impact on
network device forwarding performance. As a result, it enables a broad set of use cases: for security, forensics,
billing, troubleshooting, capacity planning, and more.
Cisco NGA empowers network and security administrators with actionable insight for resource optimization, traffic
accounting, troubleshooting, and security reinforcement. Cisco NGA supports standard NetFlow formats for export
flow information, helping ensure interoperability with existing NetFlow reporting solutions. Used in combination
with Cisco Prime Assurance Manager, it offers an integrated traffic monitoring solution for the data center.
