NMEA OneNet®—currently a draft
standard—is getting very close to completion and publication. A quick
review: Industry wanted to devise a
“standard method” to initially encapsulate NMEA
2000 messages over IPv6 with the first technological link being “wired” Ethernet for version 1.000.
OneNet is built to be extendible in order to
embrace future protocols. It incorporates many
existing universal Internet RFCs including Universal Plug and Play (UPnP). RFCs are Requests
for Comments published by the Internet Engineering Task Force (IETF) that describe methods
and behaviors applicable to the working of the
Internet and Internet-connected systems. Ethernet (IEEE 802.3) with its number of subsections,
Standards Update From Director of Standards Steve Spitzer
NMEA OneNet close to release
Internet Protocol Version 6 (IPv6) and User Datagram Protocol (UDP) are the foundations of the
architecture for the NMEA OneNet Standard.
The OneNet Draft Standard has these intercon-nected and interrelated “modules”: Base, Device
Architecture, Physical Layer, Discovery, Datagram
Service, Application Information, Gateway, PGN
Transport, Datagram Security, Application Security
Module, Certification Verification, Product Certification and Testing.
No other standard today will do what OneNet
will do. It will be the first and only maritime standard incorporating IPv6 with robust cybersecurity
built in from the beginning. The security goal is to
provide a significant defense against unauthorized
devices or commands, even on unsecured networks, or with uncertified networking equipment
or with untrained users. In the future, we will
explain how all of this works.
The OneNet Committee now has two parts:
First, the OneNet Standard Committee with a
solid Working Group and 80 industry members,
and second, a OneNet Beta Team consisting of 13
industry organizations. The plan has always been
to have a beta testing period prior to publication of
the standard. The kickoff began in January 2017.
AThis beta test allows manufacturers to build real products based on the final drafts of the standard. The OneNet Draft Standard has been frozen so the Beta Team can flush out any issues while building their products.
Plugfest a success
In June, the Beta Team had its first face-to-face
“plugfest” where sample printed circuit boards
were in operation in a laboratory setting at Rose
Point Navigation Systems in Redmond, WA. We
thank Rose Point for the fantastic facility and hospitality. We met for two-and-a-half days, sharing
openly and with transparency, discovering each
other’s product challenges and successes. Companies interacted as if they were members of the
same development team, which in some respects
for this exercise they were. Discussions included
challenges, standard language that needed clarity,
inconsistencies between modules, technical inac-curacies of the standard and others.
A comprehensive inventory of those issues was
documented, which to everyone’s delight was a
smaller list than expected. The strategy is to
review each of these with the committee and make
Rose Point Navigation Systems hosted a “plugfest” put on by the NMEA OneNet Beta Team, which consists of
13 industry organizations. From all reports, the test event was successful in terms of cooperation, interaction
