アプリケーションの概要
On-board networking systems for trains and busses require ruggedized systems to withstand both vibration and unreliable power sources. The networks often include onboard surveillance and Wi-Fi and must continue operating even when the engine is turned off.

Feature | Benefit | ||
Reliability | Redundant Power | Remains On During Power Failure |
1) Built-in surge protection, dual power sources and battery back-up 2) Ensure stable device operations for 24/7 network reliability. |
Availability | Daisy Chain | Scalable Network and Strong Transmission | With a daisy chain connection, networks can become scalable and plug as many devices as desired. This improves reliability and speed. |
Performance | VLAN | Connect Remote Devices | Network administrators can partition the networks to match the functional and security requirements of their systems without having to run new cables or make major changes in the current network infrastructure. |
Storm Control | Prevent LAN Traffic Storms | Prevents the traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on a port, reducing the system bandwidth requirements and saving CAPEX. | |
Quality of Service (QoS) | Define the Critical Networks | Networks typically operate on a best-effort delivery basis, which means that all traffic transmitting from ports has equal priority and chance of being delivered in a timely manner. When congestion occurs, the same traffic has an equal chance of being dropped. When configuring the QoS feature, specific networks can be prioritized, optimizing the network performance and bandwidth utilization. | |
Management | Link Layer Discovery Protocol (LLDP) | Access Device and Network Information | During the network discovery process device flapping issue can be occurred when the peripheral devices are connected to an unmanaged switch in the network. The Link Layer Discovery Protocol (LLDP) Filter blocks the LLDP packets exchange at unmanaged devices only without disturbing managed groups to avoid the device flapping issue. |
