NMEA Standards
NMEA OneNet Digital Interfaces
• Key Features
• Speed: up to 10 gigabit – > 40,000 times NMEA 2000
• Scalability: backbones may be other media such as such as
Fiber
• More Devices: IPv6 support essentially unlimited
• NMEA 2000 - 52
• More Power – POE will provide a minimum 15.4 Watts
• Video – Uses internationally recognized standards
• Utilizes NMEA Network (aka2000 Appendix B) Message

Why IPv6?
• Global movement underway
• Service providers IPv6 enable today
• Support of multiple IP addresses per 1 MAC Address
• More efficient addressing and routing
• Embedded security
• Enhanced quality of services
39

NMEA OneNet Digital Interfaces
Why IPv6?
• Eliminate legacy addressing issues later
• Avoid cost of dual stack implementations
• Manufacturers use “off the shelf” protocols
• Provides a platform for new and yet-to-be imagined services
for vessels
• Allows OneNet to ride this wave into the future
