Title: P1905.1, Draft
Standard for a Convergent Digital Home Network for Heterogeneous
Technologies
Scope: The standard defines an abstraction layer for multiple
home networking technologies. The abstraction layer provides a common data
and control Service Access Point to the heterogeneous home networking technologies
described in the following specifications: IEEE 1901, IEEE 802.11, IEEE
802.3 and MoCA 1.1. The standard is extendable to work with other home
networking technologies.
The abstraction layer supports dynamic interface selection for transmission
of packets arriving from any interface (upper protocol layers or underlying
network technologies). End-to-end Quality of Service (QoS) is supported.
Also specified are procedures, protocols and guidelines to provide a
simplified user experience to add devices to the network, to set up
encryption keys, to extend the network coverage, and to provide network
management features to address issues related to neighbor discovery,
topology discovery, path selection, QoS negotiation, and network control
and management.
Purpose: The abstraction layer common interface allows
applications and upper layer protocols to be agnostic to the underlying
home networking technologies. The purpose of the standard is to facilitate
the integration of 1901 with other home networking technologies.
Additionally the purpose of the standard is to define an abstraction layer
that allows: Common Network Setup among heterogeneous network
technologies defined in the PAR and provide same user experience
in the process of adding a device to the network and the same
user experience while setting an encryption key; Intelligent network
interface and path selection for delivery of packets that provides
Improved coverage performance, Improved data rate on poorest link,
Improved network capacity, Improved network reliability and QoS,
support for end-to-end Quality of Service (QoS) for different
traffic classes; Seamless / transparent path switching; Real time
mapping of connection links and paths for each traffic class /
stream; Green - energy management.
