VPN
VPN is a technology that builds a private network on a public network. The connection between any two nodes of
the VPN network does not have the end-to-end physical link required by the traditional private network, but rather
the network platform provided by the public network service provider, and the user data is transmitted in the
logical link. With VPN technology, you can establish private connections and transfer data between any two
devices on the public network.
