Consumer Requirements

Consumers who buy devices expect them to be seamlessly integrated into their data/automation network Easy to configure and register Seamless integration between IP and

non-IP networks Secure and reliable communications Intuitive controls

Seamless Integration of Automation Devices Automatic device discovery, self-

configuration, unobtrusive networking – just like other UPnP™ enabled devices Devices dynamically join a network, convey

their capabilities, and learn about the presence and capabilities of other devices

A wide selection of automation devices from multiple manufacturers from which to choose

Why Is a Bridge Needed?

Expensive and infeasible to implement UPnP™ stack in all home automation devices Motion sensors, lights, switches, etc.

Need a connection to a pervasive home automation network

A bridge connects UPnP™ enabled devices

with non-IP home automation devices

Network Architectures

Two different types of network envisioned Managed network

For small commercial applications with a service-based model

Self-installed network For home networking and home

automation environment with or without service-based model Single vendor solution Multi-vendor solution

ANSI/CEA-709.1 to UPnP™ Object Translation Layer Options

Single UPnP™ enabled device —“portal” style Presentation page-based, catch-all-devices UI interface Bridge as single UPnP device

Discovery (SSDP) is mandatory Bridge-level control and eventing are optional

Remote UI is the only access point to individual functional blocks

Network Address Devices — devices or functional blocks A collection of UPnP™ enabled devices

Each functional block or ANSI/CEA-709.1 device exposed as a separate UPnP device

Discovery, control, eventing supported with device or functional block object-level granularity

Each functional block can have a remote UI

ANSI/CEA-709.1 Network Management and Data Access Options

Option 1—LNS based managed network Standard, complete network management Includes self-configuration algorithm Database automatically synchronized to the network Standard data formatting and localization Ideal for service provider mass deployments, individual

large home networks, and enterprise solutions

Option 2—Self-installed network Includes self-configuration algorithm Bridge passively learns network configuration and

bindings No active network management: query device identity /

type only (not required – can be passive listener) Ideal for typical home networks
