Full Description
Scope
This standard defines an abstraction layer for multiple home network technologies. The abstraction layer provides a common data and control service access point to the heterogeneous home network technologies described in the following specifications: IEEE Std 1901(TM)-2010, IEEE Std 802.11(TM)-2012,IEEE Std 802.3(R)-2008, and MoCA(R) 1.1.1, 2 Other network technologies are supported by an extensible mechanism using an IEEE OUI and an XML-formatted document.
Purpose
The abstraction layer's common interface allows applications and upper layer protocols to be agnostic to the underlying network technologies. The purpose of this standard is to facilitate the integration of IEEE 1901 with other home network technologies. Additionally, the purpose of this standard is to define an abstraction layer that allows the following: -- Common network setup among heterogeneous network technologies -- Providing the 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 selection for delivery of packets that provides improved coverage performance, improved data rate on the poorest link, improved network capacity, improved network reliability and QoS, and support for end-to-end QoS for different traffic classes -- Seamless/transparent interface switching -- Real-time mapping of connection links and interfaces for each traffic class/stream -- Green energy management
Abstract
Amendment Standard - Active.An abstraction layer for multiple home networking technologies that provides acommon interface to widely deployed home networking technologies is defined in this standard:IEEE 1901(TM) over power lines, IEEE 802.11(TM) for wireless, Ethernet over twisted pair cable, andMoCA 1.1 over coax. Additional network technologies are supported by an extensible mechanismusing an IEEE OUI and an XML-formatted document. Connectivity selection for transmission ofpackets arriving from any interface or application is supported by the 1905 abstraction layer.Modification to the underlying home networking technologies is not required by the 1905abstraction layer, and hence it does not change the behavior or implementation of existing homenetworking technologies. The 1905 abstraction layer is between layers 2 and 3 and abstracts theindividual details of each interface, aggregates available bandwidth, and facilitates seamlessintegration. The 1905 abstraction layer also facilitates end-to-end quality of service (QoS) whilesimplifying the introduction of new devices to the network, establishing secure connections,extending network coverage, and facilitating advanced network management features includingdiscovery, path selection, autoconfiguration, and QoS negotiation.
