Dear Colleagues, As I stated during the nomenclature motion in P802.3cd, we (as developers of the specification) should choose terms and nomenclature which favor clear, unambiguous
communication to the end customer that uses our specification. It is for this reason that I favor the term “200GAUI” over “CCAUI”. My “day job” is that of an applications engineer; a job in which I have the distinct pleasure of assisting the many, many Ethernet customers with the selection,
design, and testing of their new products. J Most of server customer design engineers are relatively
new to Ethernet and quite challenged by the nomenclature. In the end, I usually have to make a decoder ring to explain what interface name goes with which interface and speed. (i.e. how obvious is it from the name that “SFI” is 10G?)
I strongly encourage those in the P802.3bs project to think about nomenclature over the long term and choose Arabic over Roman numerals… -Kent Unfortunately I will also miss tomorrow’s meeting. I’m of the same sentiment as Mark; it’s time to move forward with Arabic nomenclature for the benefit of our
collective customers. Nathan From: Mark Nowell (mnowell) [mailto:mnowell@xxxxxxxxx]
The 802.3bs Task Force will be handling it’s motions this week on Friday. Unfortunately many may miss this due to travel constraints – myself included. I therefore thought I’d use the reflector to share my thoughts around nomenclature as the group looks to adopt their 200GbE SMF baselines. This topic keeps coming
up as many appear to be frustrated with the continuing use of Roman numerals nomenclature for the AUI and MII interfaces. While the simplistic use of Roman numerals for 10GbE (XAUI) and 100GbE (CAUI) were somewhat easy to understand and say, we saw that with 25GbE it was unwieldy and
when looking ahead at 200 GbE and beyond (800, 1000, 1600 … it wouldn’t get any better). Therefore 802.3by switched back to the arabic nomenclature for the 25 GbE standard. The joint meeting of the 50G/NGOATH and the 200GbE SMF Study groups in Macau considered the topic and a straw poll there was overwhelmingly in favor of using Arabic
nomenclature. Obviously this is non-binding, so this week the 802.3cd group followed through with adopting its nomenclature that included the arabic usage for the AUI and MII interfaces (and of course for the PMDs etc). A lot of the discussion during the
TF meeting centered around the challenges with talking to customers, press etc to explain things to those not fully steeped into the depths of 802.3 specification writing. The motion result was Y:65 N:9 A:13. I’m hoping that the 802.3bs Task force will also follow through in a similar manner when they make their decisions on adopting 200 GbE baselines and be sure to
consider the clear direction from the SG that generated the work. Since I won’t be there tomorrow for the discussion, I wanted to share my thoughts and allow others to respond in case they may also be missing the discussion on
Friday. Regards…Mark |
