RE: Please help to clarify some things!


I'm sorry, I feel you are repeating "full duplex 10Gb 802.3 is in need of
level operations support functionality" but not adding to my understanding
of why at all. I am probably not alone.

Can we be more specific about those things that the functionality you
propose will enable us to diagnose that can not be accomplished by
collecting data in the systems attached to the Gigabit MAC and then sharing
that data or responding to queries using that MAC to transmit and receive.

Is it possible to see or manage the splice points you refer to using an
embedded protocol? I thought they were just physical splice points and that
none of the protocols you were discussing contained embedded OTDR. So the
only thing that would help me to manage these would be better insight into
BER or 'physical' level signal conditioning at the end stations. Why can't I
get at the information provided by this using SNMP, or check connectivity
using 'ping' etc. etc. What is there here that needs support in the MAC? It
may be that the world needs better management protocols but why is that a
subject for HSSG discussion?

In your document, your first and second drawings are somewhat correct.  I
that 10GbE would ever be implemented as you are showing it in your third
drawing.  In your first drawing, you need to add a fiber plant that has
like splice points every 5 km at most, access to the fiber cable by people
have nothing to do with your data, and other issues.  The traditional 802.3
environment was outgrown when full duplex 802.3 over optical transport was
standardized.  It is even possible to take full duplex 100BaseFX over WAN
distances with optical converters that are sold by several different
As seen by individuals that are attempting to create manageable enterprise
level data networks with GbE, full duplex 10Gb 802.3 is in need of protocol
level operations support functionality in order to grow to its true
