Moxa's Full Redundancy and Roaming Technologies

Turbo Ring

Enabling Ring and Media Redundancy

Turbo Ring is a proprietary self-healing protocol that enables fast

fault recovery under 20 ms at a full load of 250 switches. Turbo

Ring supports three topology options—ring-coupling, dual-

ring, and dual homing—to increase network operability, reduce

redundant cabling and eliminate planning cost, all while ensuring

seamless availability for your industrial network applications.

• Fast fault recovery < 20 ms

• Flexible ring topology

• Lower total cost of ownership

Ring Coupling Topology

Instead of one big ring, a

ring couple helps separate

distributed devices into

smaller redundant rings with

no control lines but increased

flexibility and efficiency.

Turbo Chain

Build Complex Redundant Networks

Quickly and Easily

Turbo Chain is a highly flexible self-healing Ethernet technology

designed to optimize distributed and complex industrial

networks that require fast Ethernet recovery of under 20 ms.

This breakthrough technology can create multiple redundant

networks: simply define a head and tail switch to quickly and

easily add a redundant network segment.

• Fast fault recovery < 20 ms

• Unlimited redundant network expansions

• Live node expansion without network interruptions

• Tremendous savings on cabling costs

Dual Radio WLAN Solutions

Interference-Free Redundancy for

Industrial Mobility

Moxa uses dual radio technology that transmits concurrent

wireless signals on two distinct channels to ensure interference-

free communication within 802.11 standards. When combined

with Moxa’s wired Ethernet redundancy technology and dual

power inputs, Moxa's dual radio WLAN solutions ensure

optimized availability across the entire network.

• Dual-band technology supporting 2.4 and 5 GHz bands

• Concurrent dual-radio design enabling real wireless redundancy

• Connectivity with Zero Packet Loss

Optimized WLAN Availability and Communications

Flexible enough to be used as AP, bridge, or client nodes,

dual radio devices facilitate a variety of connectivity modes for

maximum mobility, availability, and cost efficiency.

Redundant Wireless Connection Mode

Turbo Roaming

Sub-50 ms Fast Secure Connectivity

Designed for real-time connectivity, Moxa's client-enabled Turbo

Roaming unifies AP channels while roaming to reduce handover

delay to under 100 ms. Turbo Roaming can become even faster

with the addition of a wireless controller, which performs pre-

authentication and accelerates roaming to under 50 ms.

Redundant Turbo Roaming for Optimized Availability

By combining the advantages of Turbo Roaming and dual radio

redundancy, Moxa's redundant roaming can perform dual-radio

roaming with fast stable handoffs. The unique combination of

technologies creates secure wireless links that excel in highly

mobile or latency-sensitive applications.

• Roaming latency < 50 ms

• Fast mobile security

• Redundant roaming for wireless stability

Network availability directly affects the bottom line, and needs to be a primary

requirement in any network design. Moxa offers wired and wireless Ethernet

redundancy and seamless roaming throughout its portfolio of managed Ethernet

switches and WLAN devices that are designed from the very start for high

availability. Thanks to thorough redundancy capabilities, Moxa's industrial Ethernet

solutions simplify and optimize network designs with superior availability, reliability,

flexibility, and also deliver large savings on deployment time and cost.

Turbo Chain can interoperate

with Turbo Ring and RSTP/

Turbo Chain enables cost

savings with lower cabling and

Ethernet port requirements.

Dual Ring Topology

This topology employs two

rings to add reliability and

reduces cost by using a

single EDS switch for shared

connectivity. It is perfect for

difficult cabling applications.

Dual Homing Topology

This option reduces network

complexity by coupling two

separate rings with a single

EDS switch. Additionally,

it can help a PLC with

one Ethernet port extend

connectivity to another ring

or backbone networks.

AP-Client Connection Mode

This mode supports AP-client settings in two separate channels.

Operators don’t need to bother with wired switches and cables

to achieve reliable connectivity.

Bridge Mode

The adjacent master-slave

settings on two isolated

radio channels extends

interference-free transmission

with faster throughput.

Moxa’s dual radio

technology allows

flexible channel

assignments and

duplicate data

flows over 2.4 GHz

and 5 GHz bands

to achieve zero

packet loss

connectivity.
