Re: [HSSG] Reach Objectives
The 10km vs. 2km debate occurred in 802.3ae. It
was determined that the solution for 2km was virtually the same as that for
10km; therefore, the task force felt it would be better to select only one of
those reaches and 10km was it. If there is a desire for 2km and 10km
reaches in HSSG, then in my humble opinion, those wishing to support will need
to bring justification forward as to why the study group should consider
possibly increasing the number of PHYs.
Cheers,

John/Petar;
I
agree datacenter for up to 100m. How about 10GigE LR disctance
(10km) or campus 2km discussed earlier?

John,
I believe that the
Data Center distances should be 100m and 300m.

All,
We have had some
conversation on the reflector regarding reach objectives. Summarizing
what has been discussed on the reflector I see the following –
Reach Objectives
Long-Haul --> 100+ km
Metro --> 10+ km
Data Center --> 50m & 300m
Data Center Reach Segregation
Intra-rack
Inter-rack
Horizontal
runs
Vertical risers
Use this data to identify a single low-cost solution that would address
a couple of the reach objectives
Other
Areas
During the course of
the CFI there were individuals who wanted Backplane Applications kept in for
consideration, but I have not heard any further input in this area. Are
there still individuals who wish to propose Backplane as an objective?
