  1. 1905.1 Standard for a Convergent Digital Home Network for Heterogeneous Technologies Zhimeng Du 12/5/2013

  2. Catalog Background Architecture Some details Features Summary of Benefits

  3. 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.

  4. Goal Higher Layer • Provide a common interface to widely deployed home networking technologies. IEEE 1905.1 Hybrid Technology MAC/PHY 802.11 MAC/PHY 1901 MAC/PHY 802.3 MAC/PHY MoCA

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

  6. 1905.1 MAC Addressing • Between 1905.1 Devices, MAC Service Data Units (MSDU) and CTRL Message Data Units (CMDU) are sent over the 1905.1 network using 1905.1 AL MAC Address as DA. • Underlying interfaces may communicate using their generic MAC addresses for control purposes.

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

  8. Data Transfer and Forwarding SAP – Service Access Point

  9. 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 autoconfigurationprocess uses CMDUs to convey IEEE 802.11 parameters from a registrar to an AP enrollee to set up the initial configuration or renew an existing configuration of an IEEE 802.11 interface.

  10. Main Use Cases • Multipath delivery • Range Extension IEEE 1901 IEEE 802.11x IEEE 802.11x IEEE 1901 IEEE 802.11x

  11. 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.

  12. 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: 1905.1 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. … …
