Mbed Edge protocol translation
Working together: Partner and Arm responsibilities Mbed Edge • Security between gateway and Mbed Cloud • Reporting of any errors in either the protocol translation interface to the legacy interface or connection to Mbed Cloud • Maintaining & reporting status of connectivity to Mbed Cloud
Partner (Gateway developer) • Onboard and pairing of legacy devices to the gateway legacy interface (e.g. BLE, Zigbee, Modbus) • Protocol interface implementation between legacy interface and Mbed Edge • Monitoring status of protocol translation interface and connectivity to Mbed Cloud, including error reporting to the cloud (arm provides example) • Offline control and management of legacy interface in the event of loss of connectivity to Mbed Cloud • Factory provision keys into the gateway

Mbed Edge gateway management & edge compute components EdgeJS APIs
EdgeJS Apps
•
Device normalization, control, events, on-boarding
•
Control, listen, take action on devices locally without cloud
•
Alarming is a major IoT use case: Raise & lower Application specific alarming customizable
•
Apps run across all gateways in the “site”
•
Containers & Multi-tenancy – apps are protected from each other
•
Cross-platform
•
Subscribe to device events, take action
Protocol & Device Support •
•
•

EdgeDB •
Distributed database for gateways
•
Allows storage to be shared across all gateways in a site
•
Storage is local, works if cloud is down, syncs when cloud up
•
Enables local edge computing across a “site”
Mbed Edge gateway management & edge compute Gateway Management Large scale management. Status, backup & restore, configurations, logging and remote access Edge App & Device Support Deployment Deploy new edge applications (secure docker containers), new device controller components, configure, rollback, etc.
Dashboard & monitoring APIs, Alarming Deploy, manage & maintain many gateways, watch & monitor for custom alarms across many sites Roles & Permissions Assign user roles across sites, determine device access. Mobile Support Users can control & monitor devices. 15

Porting Mbed Edge enhanced stack onto new hardware Complete Port •
Entire Linux OS system with all components
•
Standard Linux OS kernel
•
All systems management capabilities
•
Radio support is the majority of time / cost
•
Known, tested system. Full support
•
Kernel patches and drivers for OEM hardware will be merged into the kernel, and Linux OS kernel for the OEM HW is provided
16
© 2017 Arm Limited
Component Port •
Key components port: Full protocol support (given that radios can be supported)
•
Time must be spent understanding & potentially updating / patching portions of the OEM’s existing BSP
•
Support will be limited
Mbed Edge Portal Key Capabilities •
Manages geographically dispersed gateways
•
Sites: allow multiple gateways to share data redundant, durable.
•
Full systems management: web UI control, logging, console if required
•
Purpose built for IoT (compare this to solutions meant for servers which are repurposed for gateways)
•
Provides insight down to the end-device level
•
Deploy IoT scripts fast using EdgeJS containers
