DNA Center Assurance Overview


Today’s Wireless Demands and Challenges

Complex to set-up and manage

Inconsistent wired/wireless policies

Wireless is defaultconnectivity today

Users expect always working wireless

connectivity

Wireless issues are hard to troubleshoot and fix: IT is reactive,

not proactive

The challenges will only grow as we move to next generation workspaces

BRKEWN-2032 14


Introducing Cisco’s DNA AssuranceTransforming network operation through actionable insights and simplicity

Today: Remediate issue

helps predict performance

Insights generated by correlating

data across WLAN, LAN, WAN, and

network services

Predictable performance to

• (Real Time) Cognitive analytics: ML-based analysis so as to detect anomalies

• Smart Dashboards: synthetic view of issues, performance across the network (comparing networking gears)

• Compare with peers: how does the network compare with similar/comparable networks

• Dynamic Relevance Learning: the system learns the user relevance, dynamically adapts, an learns from mistakes

• (Soon) coming: Predictive Analytics with dynamic close loop control
