5-4 Dual Ring

Although Ethernet Direct provides the Dual Homing technology for the industrial customers who may need to connect their switches from a field environment to the centralized backbone, some users may not deploy Cisco or HP switches. In some application cases, customers would like their backbone switches to be the same as those switches in their field environment equipped with industrial-grade protection and yet serve as the backbone network. Considering the needs, Ethernet Direct released new redundant technology called Dual Ring.

The Dual Ring is recommended when the concern is “cost” or small projects with lesser amount of switches. Dual Ring allows the connection up to two ring groups to the central backbone and the configuration will only exist in those switches with minimum 8 ports availability.
