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 1901TM-2010, IEEE Std 802.11TM-2012, IEEE Std 802.3TM-2008, and MoCA¿¿ 1.1.1,2 This standard is extensible to work with other home network technologies.The abstraction layer supports a 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 enabled in an IEEE 1905.1 network.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, interface selection, QoS negotiation, and network control and management.
Purpose
The abstraction layera??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
New IEEE Standard - Active.An abstraction layer for multiple home networking technologies that provides a common interface to widely deployed home networking technologies is defined in this standard: IEEE 1901 over power lines, IEEE 802.11 for wireless, Ethernet over twisted pair cable, and MoCA 1.1 over coax. Connectivity selection for transmission of packets arriving from any interface or application is supported by the 1905.1 abstraction layer. Modification to the underlying home networking technologies is not required by the 1905.1 layer, and hence it does not change the behavior or implementation of existing home networking technologies. Introduced by the 1905.1 specification is a layer between layers 2 and 3 that abstracts the individual details of each interface, aggregates available bandwidth, and facilitates seamless integration. The1905.1 also facilitates end-to-end quality of service (QoS) while simplifying the introduction of new devices to the network, establishing secure connections, extending network coverage, and facilitating advanced network management features including discovery, path selection, autoconfiguration, and quality of service (QoS) negotiation.
