What is a Hub-and-Spoke Network?
A hub-and-spoke network is a method for setting up a WAN over a VPN. In it, one site acts as the central hub. Then, all other sites, which are called spokes, connect to the hub. In a hub-and-spoke network, spokes must communicate through the hub in order to communicate with other spokes.
The primary advantage of using a hub-and-spoke network is that it is relatively easy and inexpensive to set up. It generally requires only one VPN connection for each spoke. It is also easy to manage, as the central focus for network administrators is typically the hub.
But a hub-and-spoke network is not without its disadvantages. With it, there is a single point of failure. If the hub loses connectivity, so do all the spokes. There can also be latency issues, as all traffic must travel through the same point.
A hub-and-spoke network is the opposite of a full-mesh network, in which every site connects to every other.
