VPNs
A Virtual Private Network (VPN) is a secure network that uses public infrastructure and typically
includes several Wide Area Network (WAN) components that may impact performance of the
VPN.
Typically, two sites are connected in a VPN network using WANs and a router. This setup provides
a secure network between the two sites, but processing is slow.
Several factors related to the network setup, including the DSView 3 software database replication
schedule and methods of device access, can affect the speed of a multi-site VPN network. The
trade-off must be made based on the network setup.
