Re: [HSSG] Topics for Consideration
This pre-supposes that there will be PMD technology solutions at these
distance "break points" which account for substantially different
economics.
If a single PMD works for up to 5km with reasonable economics, there may
not be a need for 3 of the PMDs. We need presuppose how many until we
start to understand the technologies in contention, the distances they
support, and their relative economics.
Then we just need a 2nd PMD to cover 5-40km.
This seems quite reasonable and likely.

Greg,
Based on your input it looks like we need to develop VSR, SR, LR, VLR
all at once so that we can address all of the "first wave" application
spaces shown in the CFI presentation.
If we had to prioritize our work in 802.3 what would be your view on the
relative importance of these?
Regards,
Menachem

Greg,
Should campus backbone include LR and VLR? I could see it needing a few
kms, but beyond this, doesn't it really become a "Corporate Backbone"?

Based on my experience with IX and ISP customers I see these reach
targets
in each application.
(1) Internet Exchange = VSR/SR, ISP Backbone = VSR/SR/LR/VLR , Content
Providers = VSR/SR/LR
(2) ISP Aggregation = VSR/SR/LR, Supercomputing / R&D = VSR/SR,
Broadband Aggregation = VSR/SR/LR
(3) Campus Backbone = SR/LR/VLR, Corporate Backbone = SR/LR/VLR,
Corporate Data Center = VSR/SR

John,
In the CFI presentation there was a chart showing the expected market
adoption of a higher speed Ethernet over time.
First wave shown was: Internet Exchanges, ISP Backbones, Content
Providers
Second wave shown was: ISP Aggregation, Supercomputing / R&D, Broadband
Aggregation
Third wave shown was: Campus Backbone, Corporate Backbone, Corporate
Data Center
In the same presentation there were categories for reach targets:
Backplane up to 1m
VSR up to 25 m
SR up to 100 m
LR up to 40 Km
VLR beyond 40Km
Assuming that the market adoption projection above is correct we should
match the reach definitions to these applications and see what that
means regarding the priorities for our work, i.e. :
(1) Internet Exchange = SR, ISP Backbone = ? , Content Providers = SR
(2) ISP Aggregation = ?, Supercomputing / R&D = SR, Broadband
Aggregation = ?
(3) Campus Backbone = LR, Corporate Backbone = VLR, Corporate Data
Center = SR
What are the answers to the question marks above?
Regards,
Menachem

All,
I would like to thank all those who have joined the reflector and will
be bringing information and requirements to the table in the future. I
am sure we are going to have a lot of "fun" in the future.
During our first meeting, I anticipate spending a lot of time focusing
on objectives. At the closing plenary I highlighted two issues /
objectives that the SG would have to consider:
* Tradition of 10x leap in speed
* Multiple Reach Targets
It was also presented that the focus of this effort wasn't for a desktop
application, and that the cost model needs to be considered.
I want to encourage everyone to start thinking about these areas and to
use the reflector for discussion. This will assist everyone in
providing well-thought out presentations, which will make for a better
and more productive meeting in September. :-)
