Industrial Grade Certifications IRIS IRIS (International Railway Industry Standard) is an extension of the internationally recognized ISO 9001 quality standard but is specific to the railway industry. The standard is developed by the UNIFE Group (the Association of the European Rail Industry) to attests to the quality and reliability of networks products and solutions for railway applications. ORing has been IRIS certified since 2015. ORing’s partners and customers can rest assured that their ORing solutions meet the extremely rigorous requirements in the railway industry and that ORing will...

Railway Key Technologies Hardware Bypass Redundancy technologies are great for network topologies. When one node fails, the system quickly finds another path and continues to run again. However, if two or more nodes fail in a ring structure, or if one node fails in a daisy chain structure, the network will be irrecoverable until the node problems are solved.

ORing's Hardware Bypass redundancy technology naturally and effectively avoids singlepoint power failure in daisy chain topology or multi-point power failures . For conventional wired Ethernet network, there is the Copper Interface Bypass. An ORing Ethernet switch with Copper Interface Bypass would have 2 of the Ethernet ports designated as the bypass path. Under normal circumstances, these ports would function just like any other ports. However, when one of the switches in the loop loses power, the internal bypass circuit will connect the two bypass ports to pass the traffic on to other active...

ORing also has the optical solution for hardware bypass network redundancy - Optical Interface Bypass in a dedicated optical bypass switch such as one from the IBS-102FX series. In normal operations, the Bypass switch diverts data from the Network ports to the Monitor ports. When power failure occurs, the Network data traffic is routed directly to the other Network port. Moreover, the Bypass switch has relay output for power failure warning. For different optical data transmission modes, IBS-102FX series comes in two variations - IBS-102FX-MM-LC for multi-mode optical links and IBS-102FX-SS-LC...

IEC-61375-2-5(TTDP) Train topology is dynamic and frequently changes since cars are constantly added, removed, or replaced. Every time the order of the train cars changes, the network must be reconfigured, which is very time-consuming and prone to errors if it's done manually. TTDP (Train Topology Discovery Protocol) protocol has thus been developed to enhance the efficiency of railway network reconfiguration. The protocol enables network switches to negotiate automatically with other network devices after the network topology is changed and will assign an IP address to the network devices based...

X-Roaming IEEE 802.11 networks can only transmit data within a few hundred meters. As for mobile data application, the devices should handoff from one access point to another. ORing’s X-Roaming technology, which is available in all of ORing’s new wireless access point models, reduces the handoff time between two different access points to less than 100 milliseconds, and makes seamless wireless communication possible. With ORing’s X-Roaming technology, the client can roam seamlessly among different access points. ORing also provides the feature of load balance — to prevent traffic jam of mobile...

Cellular Load Balance for multiple WAN interface Load balancing distributes traffic across multiple broadband connections such as multiple 3G/4G links when a single resource is overloaded to enhance the lSP A scalability and availability of mission critical, IP-based services. Load balancing can also achieve redundancy when one or more connections fail and hence increase network reliability. Session Load Balancing assigns each session to one of the cellular connections. Normally, all connections are used simultaneously. When one of the connections fails, all traffic is sent over the remaining...

802.11P Modified from 802.11a, 802.11p is a standard to ensure secure wireless communications in a vehicular environment. Also known as WAVE, 802.11p covers communications from vehicle to infrastructure, vehicle to vehicle, and vehicle to pedestrian. This standard works in 5.9GHz band with seven channels of 10MHz, one for control and six for data services. As there is no need to associate with base stations, data can be transmitted more quickly. Furthermore, receivers have better noise rejection abilities due to no adjacent interference. The standard enables fast wireless communications in the...
