• What is RDKB ?• Unique Features• Why Use RDKB ?• Component based Architecture.• Components• High Level Architecture• Getting Access• QA
AGENDA
• RDKB – Broadband profile for RDK• Shared BSP infrastructure with RDK Video• Shared logging, crash reporting, system management• Over 2 million devices deployed
INTRODUCTION
• DOCSIS 3.0• eMTA• Private Wi-Fi • Public Wi-FI• MoCa 2.0• eMTA• Local Admin Pages• MoCA extender support• Bridge Mode support • IPv6• Cloud Gateway support (VRG)• HNAP protocol support for Home Security• 2.4/5G Band support• Provisioning• WPS• SNMP• TR-69
RDKB FEATURES
• Http Code Download• Xconf support for finer control of code download• WebPA Support• RDK Logs• RDK Metrics• Video over Wi-Fi • Wi-Fi-MoCA bridge for Video• IP table for packet tracking• Support for Cloud Admin• Forced Wi-Fi personalization• Connect/Disconnect Notification • RSSI Reporting• Self Healing
RDKB UNIQUE FEATURES
• 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
• High Software Velocity– 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 with TR-181, WEBPA with TR-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
• WEB-PA– Complete solution for
• Device Manageability• Control• Understands TR-181 model• Head-end component available for adoption
– Is available as opensource contribution.• Built on Yocto Project/OpenEmbedded Build infrastructure
– Vast set of packages available– Support wide range of SOCs out of box
• RDKB Emulator implementations as reference on Yocto/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
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 ( Run Time APIs )
– only adds new parameters
