OMB CIRCULAR NO. A-119 Revised (February 10, 1998) Federal Participation in the Development and Use of Voluntary
Consensus Standards

Voluntary consensus standards bodies" are domestic or international organizations which plan, develop, establish, or coordinate voluntary consensus standards using agreed-upon procedures.
The FCC has determined that DLNA produces open industry standards
CVP-2 is believed to comply with certain FCC requirements that come into effect on June 2, 2014. (FCC Memorandum Opinion and Order DA 12-1910 http://transition.fcc.gov/Daily_Releases/Daily_Business/2012/db1128/DA-12-1910A1.pdf

Deployed Home Networking Technologies
Energy Efficient Ethernet (EEE) is a part of the whole Home Networking solution Most homes do not have Ethernet (CAT-5/6) between rooms
Even if present, is not always in convenient location
So most service providers end up deploying “No New Wires” networking technologies:
HomePlugAV / Green PHY over electrical mains
MoCA over TV/Cable/Satellite coaxial cabling
Wi-Fi – no wires
15Broadcom Proprietary and Confidential. © 2012 Broadcom Corporation. All rights reserved.
MoCA 2.0 Power States
M0 (Active):
Normal Operating Mode: Full Functionality
M1 (Low Power Idle):
Lower power than M0
RX Only Mode: Node stays “ranged” on the network, but does not transmit data packets
Can be returned to M0 via Wake on MoCA (WoM) packet
M2 (Standby):
Lower power than M1
Monitors Beacons every 10ms – 100ms: Minimal active state, but has a relatively fast path for readmission
Can be returned to M0 via Wake on MoCA (WoM) packet
M3 (Sleep):
Lower power than M2
Issues Heartbeat every 1 – 255 seconds: Inactive state, but Network Controller reserves the Sleeping Node’s place on the network
A MoCA 1.x node in MoCA network operates in Power State M0 only

DLNA Energy Management

Network Power Signaling Assumptions
Device Services and Interfaces are modular
The entire set of functional blocks inside a Physical Device will not simply be in "sleep" or "awake". Some may be "awake" while some may be "asleep".
Internal power controller makes all decisions about how to manage its resources within a physical device.
An external requesting device cannot really know the details inside of another physical device.
Multiple clients will have unique requests
Even when power saving, network communication must be maintained.
May have delayed/discard characteristics in some power states.
Devices are meaningless without network connectivity
Home network connectivity can never really be totally asleep...

DLNA / UPnP Network Power Signaling
DLNA Low Power / UPnP EnergyManagment Service
http://upnp.org/specs/lp/energymanagement1/
Service Subscription
Allows clients to indicate which resources are needed from a server
Server can make informed choices on how to reduce its power while limiting disruption to the clients that depend on it.
WakeOnPatterns
“Wake On” does not really have standards.
Allows a device to advertise on the network this specifics of signaling (ie, Wake On Patterns) to change its network interface state.
Proxied Network Interface Information –
Allows a server device to be immediately discoverable by client devices even if the server devices network interfaces are currently non-active.

Network Interface Mode of Operation
IP-up: IP interface is fully operational. UPnP services may be available
IP-up-Periodic: IP interface will be periodically unavailable for durations of 2 second or less when the physical interface is placed in a low power mode of operation
IP-down-no-Wake: IP interface is down
IP-down-with-WakeOn: IP interface is down. IP interface can be woken externally
IP-down-with-WakeAuto: IP interface is down in doze state for duration of more than 2 seconds. IP interface will be woken internally only
IP-down-with-WakeOnAuto: IP interface is down in doze state for duration of more than 2 seconds. IP interface will be woken internally or can be woken externally

No single connectivity technology has 100% Coverage in every region in every home
As of 2008, only 11% of homes have CAT5
Part of a home may be on the other PLC phase reducing performance
Wi-Fi coverage is dependent on construction and density
Seamlessly add multiple connectivity
technologies and the picture changes

The Future | Hybrid Home Networking
IEEE 1905.1 defines an abstraction layer that provides a common interface for the most compelling and deployed home networking technologies in the market.
A broad base of industry-leading chipmakers, equipment manufacturers and service providers are collaborating to bring IEEE 1905.1 to fruition.
Great for the industry: Enhances user experience and enables next generation connected services for consumers.
