SD-Wan Hub and Spoke
SD-WAN Hub and Spoke is the traditional approach to creating a Wide Area Network (WAN) over a virtual private network. “Hub and Spoke” is also referred to as a wagon wheel network.
With the Hub and Spoke model a single site operates as the hub or central site and is the traditional approach to creating a wide area network (WAN). Other sites connect back to the main hub through VPN links acting as spokes in the wheel. These remote branches each communicate through the central hub in order to reach other spokes.
Hub and Spoke networks are easier to design and manage, and all security services can be located in the centralized hub allowed all traffic to be inspected and secured at a single point in the network. This network design also streamlines tasks such as web filtering, load balancing, and caching data in a single location.
