AUTOMATING @ EXPONENTIAL SCALETHE SELF-DRIVING NETWORK


• Standards-based network interfaces & data models

• Automated network provisioning, management, & operations

• Minimal declarative intent

• Actionable Information –Real-time telemetry

• Integration with full IT infrastructure

• Rules-based actions based on infrastructure events - Closed loop automation

• Machine learning algorithms

• Pre-Programed machines make decisions & drive network changes

• Humans make decisions where machines cannot

• Deep learning algorithms drive operation

• Correlated w/ historical & real-time network & non-network info

• Humans design & monitor algorithms – time freed up for innovation
