Absolutely. It will be wonderful to get such consolidated
information/presentation.
Thanks,

Having followed the ongoing discussion, this group needs to have solid
answers for the following issues:
1. Comprehensive list of all LEGITIMATE use cases for Residential
Ethernet
2. Technical and business reasons why some, if not all, of the use cases
cannot be addressed by the existing QoS solutions
3. All fundamental characteristics of the Residential Ethernet that are
required to address the use cases
And I think, some of these fundamental RE characteristics that cannot be
addressed by existing IP-based QOS (consisting of a combination of
admission control/traffic shaping, QoS scheduling (such as WFQ), and
reservation signaling) should include at least:
- (virtually) CONSTANT, SUB-MILLISECOND latency for the
real-time traffic
- (virtually) ZERO/SUB-FRAME jitter for the real-time traffic
- (virtually) ZERO packet loss for the real-time traffic
- SIMPLE bandwidth/connection reservation scheme
IMHO, by clearly highlighting the technical requirement that cannot be
addressed by the existing QoS solutions, people can start seeing the
need for an alternative solution.

Kevin:
Ask the Consumer Electronics Association if Dolby 5.1 ==> Dolby 6.0 is
selling well. Take a listen sometime.
Also, remember that we in the tech industry are atypical of most of the
consumer product customer base.
I'd recommend that you book your rooms in Vegas now for the Consumer
Electronics show in Jan. to understand this industry (why we called it
"Residential Ethernet"). You cannot assess unless you can experience
it. FYI attendance at the CEA show has far surpassed the attendance of
any of our technology or computer/communications trade shows. Been to
Comdex lately?
