RDKB is Open Source Broadband Gateway platform stack, built on top of an OpenEmbedded build framework. It’s currently deployed on all Comcast broadband home gateways. This talk will introduce the internals of RDKB and features forming the basis of the IoT framework for the Comcast Network.

RDKB UNIQUE FEATURES

6. • Zigbee HA 1.2 Hub
• Thread
• Bluetooth LE
• Device System Bridge to connect Zigbee/Thread/BLE
• Alljoyn/OIC Connectors
• IoT Cloud Adapter for Cloud Connectivity
• Local Rules Engine
• Easy Onboarding of devices
IOT FEATURES

7. • High SoftwareVelocity
– Architecture supports plug-in component modules – all using Linux D-Bus
– Teams can create components in parallel
– Leverages open source within Architecture Framework and within components
• Supports multiple management protocols and data models
– TR-069 withTR-181,WEBPA withTR-181, SNMP, CLI via UART/SSH, easily extensible
• Support single and multi-core CPU architectures
• No component level code change needed to repartition software
– D-Bus extends common architecture across CPUs
• Easily portable to support multiple SoC vendors
– Supported through component level abstraction layers
– Leverages the ability to repartition across single core, multi-core and multi-CPU
• Supports IOT
– AllJoin
– Iotivity (Part of OE/Yocto supported layer, can be pulled in on demand)
– Thread
• Integrated logging infrastructure with head-end
ADVANTAGES OF RDKB

8. • WEB-PA
– Complete solution for
• Device Manageability
• Control
• UnderstandsTR-181 model
• Head-end component available for adoption
– Is available as opensource contribution.
• Built onYocto Project/OpenEmbedded Build infrastructure
– Vast set of packages available
– Support wide range of SOCs out of box
• RDKB Emulator implementations as reference onYocto/OE available
• Licensed under RDKM Apache license.
• Value addons from other infrastructures available
– E.g. OpenWRT packages
• Clean separation between modem, voice and data
ADVANTAGES OF RDKB

9. COMPONENT BASED ARCHITECTURE
• Standard message primitives used for all components
• Messages are passed over D-Bus IPC mechanism
• Adding new services doesn’t change APIs ( RunTime APIs )
– only adds new parameters
