[802SEC] Comments on P802.3 PARs
David
Hear are my comments:
P802.3cd
PAR comments:
2.1: The title appears to be wrong "Approved Draft Standard for
Ethernet", shouldn't it be "Standard for Ethernet"? If this is a
myProject issue, when simply refer it to the NesCom administrator.
5.2.b: The scope defines data rates but not the media or distance (or
equivalent measure). Is wireless a valid media for this project?
Free-space optics? Near-field? Please specify the targeted media
(copper, backplane, optical, carrier pigeon, ...) and the target
distance (e.g., typically 1 m).
CSD comments:
Distinct Identity: The reasoning here indicates that 802.3bs will have
200 Gb/s, but not over "backplanes, twin-axial copper cables and MMF"
However, as the scope does not limit the media, this project appears to
be a superset of 802.3bs. If it isn't, the scope should be written to
restrict the work so that it does not overlap.
P802.3cc
PAR comments:
5.2.b: "as amended by the IEEE P802.3by project." The scope is to be
written as present tense, i.e., that IEEE P802.3by has been completed
(otherwise it would not amend IEEE 802.3-2015). However, once .3by is
approved, it is automatically part of 802.3 and you don't need to call
out all of the amendments.
I suspect the problem is that 5.3 should be marked as Yes and IEEE
P802.3by be listed. Then delete "as amended by the IEEE P802.3by project."
5.2.b: The need states that the goal is 100 m SMF, this should be stated
in the Scope, i.e., change "operation by specifying" to be "operation at
reaches greater than 100 m by specifying"
CSD comments:
Distinct Identity: The reasoning states that there is no other 25 Gb/s
PHY with > 100 m reach, yet this is not a requirement in the scope. If
this requirement is added to the scope, then the statement here would be
true.
802.3bt
PAR comments:
5.2.b: Present tense is required in the scope, hence the PAR cannot say
"may be enabled". Change to "are enabled" or "are optionally enabled"
or "are enabled as an option"
8.1: Typo, change "5.2B" to be "5.2.b"
CSD comments: No comments.
802.3bs
PAR comments:
5.2.b: The physical media is not identified for these data rates nor is
the reach. Please add to the scope that these data rates are defined
for single-mode fiber and add a range target, e.g., at ranges greater
than 1 km
CSD comments:
Distinct Identity: Change "200 Gb/s over single-mode fiber and 400
Gb/s Ethernet" to be "200 Gb/s and 400 Gb/s Ethernet over single-mode fiber"
Thanks
