Hi John.
Thank you for bringing forward these docuemnts.
I think 802 has to address these backup power issues and
mostly, operation continuance with backup power, as from a potential ruling will
follow requirements on the networks and therefore, the network equipment to
"survive" very long power outages. This may impose many additional costs on the
equipement and cause large concerns on the power consumption of the equipment.
Thee is also an issue raised about equipemnt power supply standardization, from
the PHY side, with set supply voltages which may need to be standardized to the
actual power connectors. I am convinced the industry can adjust. My main concern
is "at what cost: as we all know that any increased cost may cause issues and
slow down deployment of IP based networks. Moreover, there are requirements here
that may require every switch, every backup ower source to need to be managed
which implies a storm of MAC addresss and IP address consumption by the industry
so each device becomes manageable or at least, can be interrogated. For example,
most consumer grade network switches today do not have a MAC address, an
externally reachable IP address although they do transport and distribute IP
traffic. There is also a question heer about "green" devices which go to
sleep...
Both wired eth devices (POE) and wireless devices may be
impacted. POE specifes 48Volts as std. Here we see something along the lines of
3.3 or 5V proposed as std. So 802.3 may need to get involved to either adapt or
protect 802.3AF. 802.1 may need to be involved too, as we all know the wide
popularity of locally administered IP addresses and NATting. Here, the service
provider may be required to contact deices "inside" the consumer network and the
configuration here of routers may be very problematic for consumers. There is
also a question on all wireless stds that may transport VoIP... probably all 802
wireless technologies may be affected.
There are talks of over 40 million affected consumers, my
translation, probably over 40 million home IP networks and home edge routers.
Maybe something may be needed that allows the customer CPE equipmenet to
"certify" the link form the CPE client right down to the "VoIP" host that all
the equipement through which hs IP trafic flows to the "E911" service is indeed
"backup protected". I beleive there are PHY, MAC and higher layer issues across
the board here.
Just my 2 cents worth,
Ivan Reede
