Adaptive Networking overview

Adaptive Networking is a suite of tools and capabilities that enable you to ensure optimized
behavior in the SAN. Even under the worst congestion conditions, the Adaptive Networking features
can maximize the fabric behavior and provide necessary bandwidth for high-priority, mission-critical
applications and connections.
The Adaptive Networking suite includes the following features:

Bottleneck detection
The bottleneck detection feature identifies devices attached to the fabric that are slowing
down traffic. Bottleneck detection does not require a license. See
page 416 for information about this feature.
Top Talkers
The Top Talkers feature provides real-time information about the top "n" bandwidth-consuming
flows passing through a specific port in the network. Top Talkers requires an Advanced
Performance Monitoring license. See
about this feature.
