Pipeline: integration challenges
Central Systems
Monitoring - temp, pressure...Control - valves…
4000 devices integrated, need to add 8000 more BUT:• Satellite network saturated due to polling of device• VALMET system CPU at 100%• Other applications needed access to data ("SCADA prison")
Proprietary polling protocol

low-bandwidth,expensive comms
• Scalability for whole pipeline! • Network traffic much lower - events pushed to/from devices and report by exception• Network cost reduced• Lower CPU utilization• Broken out of the SCADA prison – data accessible to other applications

Original Design Goals
• To make it simple to connect the M2M (physical) world to the traditional IT world
• Expect and cater for frequent network disruption – built for low bandwidth, high latency, unreliable, high cost networks (cost per byte)
• Expect that client applications may have very limited resources available (8 bit controller, 256kb ram)
• Provide loose coupling to support dynamic system environments where high volumes of physical world messages and events need to be made available to enterprise servers and other consumers in ways that may not have been originally anticipated.
• Provide multiple deterministic message delivery qualities of service to reflect tradeoffs between bandwidth, availability, and delivery guarantees
• Capable of supporting large numbers of devices (10k MQTT clients)
• Simple for application developers and implementers of the protocol
• Publish the protocol for ease of adoption by device vendors and third-party client software enabling support for a proliferation of platforms, technologies and networks that are driven by very diverse equations of cost, technology and physical constraints.
• To be industry agnostic

MQTT the Protocol
Watson / Presentation Title / Date12
• A producer publishes a message (publication) on a Topic • A consumer subscribes (makes a subscription) for messages on a Topic• A message server matches publications to subscriptions
• If none of them match the message is discarded• If one or more matches the message is delivered to each matching consumer
Publish / Subscribe has three important characteristics:1. It decouples message senders and receivers, allowing for more flexible applications2. It can take a single message and distribute it to many consumers3. This collection of consumers can change over time
Publish / Subscribe Messaging (One to Many)
Watson / Presentation Title / Date13
§ MQTT protocol control packets:• Fixed header (2 bytes)
• Variable header (optional, length varies)• Message payload (optional, length encoded, up to 256MB)
§ Fixed header indicates the packet type, the length of the payload and Quality of Service
§ Variable header contents depend on packet type• Message ID, Topic name, client identifier and so on.

§ Every message is published to a Topic§ Topic names are arranged in a Topic hierarchy
• Levels separated by “/”
• Implementations can pre-define individual Topics, prescribe a scheme for Topic names, or allow free rein to publishers or subscribers
§ Subscriptions can use wildcarded topic strings
• Single-level wildcards “+” can appear anywhere in the topic string
• Multi-level wildcards “#” can only appear at the end of the string
• Wildcards must be next to a “/” separator
§ MQTT topic strings can be 64KB long

Recent IoT Use Cases
As KONE started to connect their escalators and elevators to IoT, the data started to grow exponentially. From all of this data, KONE has been able to create new services using live machine conversations – to tailor specific maintenance for elevators based on real data.
Innovation solutions are accelerated for KONE, a global provider of building elevator and escalator technology, modernization and maintenance
70% decrease expected in customer service callTime – improving service levels and customer sat.
50% reduction projected in service and parts provision costs
Reduces IT costs with cloud-based hosting and solution as a service delivery
Whirlpool connected appliances provide new link from customers to warrantee services, product design and automated retail replenishment
Using IBM Watson IoT Platform to stream data directly to the cloud, SilverHook was able to quickly build an application on the IBM® Bluemix™ platform to analyze and deliver insights in a useful format to racers and fans. The team completed a prototype in 40 % less time, delivering a comprehensive analytics solution with data visualization in just three months.
SilverHook Powerboats uses sensor data collected from racing boats to improve the decision-making abilities and safety of racers and to enhance the fan experience
