Shipyard

アプリケーションの概要

Automated offshore surveillance is required to monitor shipyard activities, network devices must be able to withstand extreme heat, humidity, EMI (electromagnetic interference), corrosion, shock and vibration conditions

考慮事項

  • DNV and GL certified devices that are vibration-proof, corrosion-proof, and resistant to temperature fluctuations (from -40°C to 75°C or -40°F to 167°F ).
  • PoE+ functionality with Gigabit backbone for high-bandwidth real-time video, voice, and data communications.
  • Remote monitoring capability with a user-friendly, network management system and web-based GUI.
  • Future-proof fiber connectivity for long distance transmission from shipyard to the control room.

Volktekのメリット

  Feature Benefit
Reliability Redundant Power Remains On During Power Failure Built-in surge protection, dual power sources, and battery backup ensure stable device operations for 24/7 network reliability.
USB Port Lower OPEX for Configuring and Upgrading The USB flash drive port has multiple functions including 
- Upgrading undeployed switches
- Eliminates the need for notebook or network access for installation and upgrades
- System-config and local Syslog back-up
Availability Link Redundancy Fast Network Recovery Link aggregation and dual-homing rapidly react to physical link failure and recover immediately (milliseconds) or provide an alternate pathy link to support continuous transmission.
Performance 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.
Security 802.1x RADIUS / TACACS+ Secure the Network by Authenticating the Users Allows the network administrator to specify a whitelist of allowed MAC addresses, allowing only those devices to connect to the network.  It also limits the number of devices connected to a single downlink port known as Dynamic Assignment.
e-mail Alarm Triggered Events Alert Via Email Sends email alerts via SMTP to notify the administrator if real-time problems occur such as firmware or configuration changes, device status, link connectivity status, etc.  These triggered events help administrators to quickly identify, isolate and resolve network issues.
Management Link Layer Discovery Protocol (LLDP) Access Device and Network Information Managed switches provide management of SNMP traps or alert messages sent from a remote SNMP-enabled device to a center SNMP server.
PoE ON / OFF + PD Alive Check Intelligent PoE+ for Powered Devices PoE switches can enable or disable the power supply to the powered devices.  The powered ports can send keep-alive checking packets to the devices to increase system reliability.
