Internet Connection Failover

Businesses have come to rely upon access to the Internet. For many companies, the loss of Internet availability drags their productivity to a screeching halt. In order to guard against interruption, leading companies have provided reliable solutions to provide resiliency in Internet connectivity.

By using a combination of two separate Internet circuits, supplied by two different Internet Service Providers (ISPs), and two firewall appliances, continuous availability can be maintained even if a firewall or the Internet circuit itself fails. For example, two SonicWALL TZ-170 firewall appliances are each connected to a T-1 circuit supplied by ISWEST and a DSL circuit provided by SBC. In this configuration, Internet service will remain available even if a firewall or individual circuit becomes unavailable.
