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
