Standard for a Convergent Digital Home Network for Heterogeneous Technologies Zhimeng Du 12/5/2013

Catalog Background Architecture Some details Features Summary of Benefits

Background Multiple connectivity technologies are needed due to the wide variety of applications, regions, environments and topologies. Each of these different technologies has a unique interface to higher layer entities. Software and hardware design complexities in multi-connectivity devices.

Goal Provide a common interface to widely deployed home networking technologies. IEEE Hybrid Technology IEEE Hybrid Technology MAC/PHY MAC/PHY MAC/PHY 1901 MAC/PHY 1901 MAC/PHY MAC/PHY MAC/PHY MoCA MAC/PHY MoCA Higher Layer

Architecture HLE – Higher Layer Entity ALME - Abstraction Layer Management Entity SAP – Service Access Point SME – Station Management Entity

MAC Addressing Between Devices, MAC Service Data Units (MSDU) and CTRL Message Data Units (CMDU) are sent over the network using AL MAC Address as DA. Underlying interfaces may communicate using their generic MAC addresses for control purposes.

Protocol Stack MSDU - MAC Service Data Unit AL – Abstraction Layer ALME - Abstraction Layer Management Entity SME – Station Management Entity

Data Transfer and Forwarding SAP – Service Access Point

Features Topology discovery : query(unicast), response(unicast), notification(relayed multicast) Security setup : push button configuration, user configured passphrase/key, near-field communication network key Access point auto-configuration : The AP autoconfiguration process uses CMDUs to convey IEEE parameters from a registrar to an AP enrollee to set up the initial configuration or renew an existing configuration of an IEEE interface.

Main Use Cases Multipath delivery Range Extension IEEE 1901 IEEE x IEEE 1901 IEEE x

Summary of Benefits Ease of Use : Use common setup procedures for adding devices to a network, establishing secure links, implementing QoS, and managing the network. Fallback : When a link goes down temporarily or is congested, an alternative route is available. Aggregated Throughput : Use multiple interfaces for maximizing throughput. Multiple Simultaneous Streams : With applications such as interactive TV, even a single person may be watching multiple streams simultaneously.

Summary of Benefits Load Balancing : Intelligently distribute multiple video streams over different paths to limit congestion and maintain reliability. QoS : Uniformed Prioritized QoS over multiple technologies. Security : allows devices to be configured the same way with a simple button push, for example. Advanced Diagnostics : The overall network monitors itself. Mobility : Wireless connectivity supports mobile handsets, and tablets. Universal Connectivity : Can connect to the hybrid network from every room in the house without having to be aware of which part of the network their device is currently interfacing. …
