Network topology
The following describes local and remote server network topologies.
Local network topology
A local network topology is illustrated below. With the local topology, the device does not require internet access as the server is located in the same local network.

Remote network topology
A remote network topology is illustrated below. With the remote topology, the device and server are located at two separate networks. Internet connection is used to connect the two local networks and allow the device to connect to the server.
