The secondary substation router aggregates traffic from various IEDs and RTUs and routes traffic to both primary and secondary regional Control Centers hosted by the DSO via 4G LTE. The router encrypts the application traffic using OpenVPN and IPSec tunnels for maintaining confidentiality of application data over the public network. The headend router in the DSO Control Center aggregates various secured tunnels from multiple substations and decrypts the encrypted traffic; the traffic is routed after decryption to various SCADA application.
