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:
• Top Talkers
• Traffic Isolation Routing
• QoS Ingress Rate Limiting
• QoS SID/DID Traffic Prioritization
• Bottleneck Detection
