SD-WANs can connect several branch locations to a central hub office or cover multiple locations. Because this technology is abstracted from hardware, it is more flexible and produces higher degrees of reliability than a standard WAN. This approach enables companies to achieve synergies derived from a variety of bandwidth providers that meshed seamlessly to optimize uptime, network data flows & traffic patterns, failover and host of related benefits.
There are 4 main components of SD-WANs.
- Edge connectivity abstraction
- WAN virtualization
- Centralized management
- Elastic traffic management
