Ring topology is a very popular and cost-efficient way to build a network and is recognized within the industry as being one of the most effective solutions to avoid network downtime. Moxa’s Turbo Ring technology allows networks to recover within 20 ms* on a network with up to 250 nodes.

*Note: 10G/1G Ethernet recovery time < 50 ms

Moxa’s Turbo Chain is a very flexible redundancy technology that offers unlimited redundant network expansion and is designed for use on widely distributed networks. Turbo Chain outperforms traditional ring topologies by providing superior flexibility, unrestricted expansion, and simplified configuration that allows network operators to reduce deployment costs when connecting separate redundant rings together.


V-ON ensures that simple and complex networks can recover within milliseconds in the event of a connection failure. V-ON was designed for multicast network applications, such as industrial automation PLCs and video surveillance systems. When this technology is combined with either Turbo Ring or Turbo Chain, you can provide redundancy for your whole network.

  • Layer 2 transmission recovery < 50 ms for unicast and multicast networks
  • Layer 3 transmission recovery < 300 ms for unicast and multicast routing networks
  • Millisecond-level router redundancy

Parallel Redundancy Protocol (PRP) and High-Availability Seamless Redundancy (HSR) are two technologies that provide seamless transmission even when part of the network fails. PRP achieves active network redundancy by packet duplication over two independent networks that operate in parallel, whereas HSR is designed primarily for ring topologies.
