A ring topology is a network configuration where each networked device is connected to two other devices on either side of it to form a circular “ring” data path. When data is transferred in a ring topology, the data is sent in one direction along the single continuous pathway. Each device has a repeater that will forward the data until it reaches the device in the topology that the data was intended for.
At Antaira Technologies, they recognize the importance of a reliable, redundant network. Many of their industrial Ethernet switches support the ring network redundancy function. Using the market’s open standard ITU-T under G.8032 ERPS (Ethernet ring protection switch) protocol, our devices have a minimal network recovery time of less than 50ms. The ERPS protocol also provides recovery switching for Ethernet traffic while preventing loops from forming at the Ethernet layer.
In addition to ERPS devices, they also stock industrial Wifi repeaters to further enhance network stability in networks that require wider coverage.
