Key Concepts
SDN Benefits
- Centralized Control: Single view of network
- Programmability: API-driven configuration
- Agility: Rapid service deployment
- Cost: Reduced hardware dependency
- Automation: Reduced manual tasks
Overlay vs Underlay
- Underlay: Physical network (switches, routers)
- Overlay: Virtual network on top (VXLAN, NVGRE)
