What do VPN topologies define?

VPN topologies specifically define how peers and networks are connected within a VPN. This involves the arrangement and structure of the connections between different endpoints, such as remote users or branch offices, and the main network. Understanding the topology is crucial for determining how data flows, how security is enforced, and how resources are accessed across the VPN.

For example, a hub-and-spoke topology connects multiple clients to a central server, making it efficient for managing connections and controlling access. In contrast, a mesh topology allows for direct connections between all nodes, enhancing redundancy and reliability. Thus, the choice captures the essence of VPN functionality by illustrating how different components interact and establish secure communication paths.
