2.1 AR500 as a Industrial Router
As the industrial router, the AR500 can connect a transformer substation to a dispatch center
(monitoring center) through the Internet, and establish a GRE/IPSec VPN or Dynamic Smart
Virtual Private Network (DSVPN) tunnel to secure data transmission. A transformer substation
can also use dedicated lines to connect to a dispatch center on a private network through an
AR500.
As shown in
, the dispatch center connects to the Internet, and transformer substation
A and transformer substation B connect to the Internet through the AR500. A GRE VPN or
IPSec VPN tunnel is established between the dispatch center and transformer substation A/B so
that the dispatch center can communicate with transformer substation A/B and transformer
substations A and B can communicate through the DSVPN tunnel.
You can also use an AR500 to directly connect the transformer substation to the dispatch center
through dedicated lines to construct a private network.
