Minimize Downtime in Your Critical Applications with Uninterrupted System

Data packets transmitted in Ethernet-based communication are commonly divided into unicast, broadcast, and multicast categories. Various redundancy protocols exist to aid network operators in constructing a dependable network for unicast and broadcast communication. A key measure of network reliability is its ability to swiftly recover from transmission errors. Instead of taking approximately 10 seconds like RSTP (Rapid Spanning Tree Protocol) to address disruptions, Moxa’s network technology, Turbo Ring and Turbo Chain, can rapidly switch to backup paths in under 50 ms. This agility is crucial for maintaining continuous data flow and preventing downtime in critical applications even during network interruptions.

When it comes to multicast networks, ensuring reliable communication poses a more complex challenge. Multicast communication predominantly relies on IGMP (Internet Group Management Protocol) to facilitate seamless network-wide communication. However, in the event of a network error, IGMP may take up to 125 seconds to update the multicast transmission path. This long recovery time is unacceptable for mission-critical scenarios, such as when a system error disrupts a PLC controlling factory operations, resulting in production stoppage and financial losses.

The network deployment diagram commonly seen in factory automation is illustrated below. Reliable communication between robotic arms and conveyor belts is essential for uninterrupted production. Interruptions in implicit communication channels may lead to critical system shutdowns if not rectified within a short timeframe to prevent damage to equipment and personnel.

To prevent disruptive downtimes in networks where any downtime is intolerable, Moxa has introduced a rapid recovery multicast technology. This innovative technology, combined with Turbo Ring or Turbo Chain, allows network operators to establish highly redundant networks, ensuring continuous operations even in the face of network disruptions.

Moxa’s V-ON technology provides swift recovery times for layer 2/3 multicast communication, guaranteeing layer 2 multicast recovery in under 50 ms. Network operators seeking to leverage Moxa’s rapid recovery technologies can enable V-ON support on EDS-500E Series, IKS, and ICS switches by selecting “multicast fast forwarding” in the user-friendly web interface available for free download with the latest firmware update.
