Please note the following

IBM’s statements regarding its plans, directions, and intent are subject to change or

withdrawal without notice at IBM’s sole discretion.

Information regarding potential future products is intended to outline our general product

direction and it should not be relied on in making a purchasing decision.

The information mentioned regarding potential future products is not a commitment,

promise, or legal obligation to deliver any material, code or functionality. Information

about potential future products may not be incorporated into any contract. The

development, release, and timing of any future features or functionality described for our

products remains at our sole discretion.

Performance is based on measurements and projections using standard IBM

benchmarks in a controlled environment. The actual throughput or performance that any

user will experience will vary depending upon many factors, including considerations

such as the amount of multiprogramming in the user‟s job stream, the I/O configuration,

the storage configuration, and the workload processed. Therefore, no assurance can be

given that an individual user will achieve results similar to those stated here.

• HTTP revolutionized how people consume data– simple request/response model

– Not designed for wireless, no QoS

– Slow and unreliable on mobile networks

– Using for polling causes blindspots

• M2M and Sensors has different challenges– Requires real-time event-driven

– Emitting information one to many

– Listening for events as they happen

– Sending small packets of data in huge volumes

– Reliable push over unreliable networks

HTTP IS NOT ENOUGH


“.. performance improvements designed to make your messaging experience even better. To do this without killing battery life, we used a protocol called MQTT … designed to use bandwidth and batteries sparingly… phone-to-phone in hundreds of milliseconds, rather than multiple seconds.”

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")

• 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

Enter MQTT


Introducing IBM MessageSight

• A secure, easy to deploy appliance-based messaging server that is

optimized to address the massive scale requirements of the machine

to machine (m2m) and mobile use cases.

• A million connections, and millions of messages per second

• It is designed to sit at the edge of the enterprise and can extend your

existing messaging infrastructure or be used standalone

MessageSight


A producer publishes a message (publication) on a topic (subject)

A consumer subscribes (makes a subscription) for messages on a topic (subject)

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 applications

2. It can take a single message and distribute it to many consumers

3. This collection of consumers can change over time, and vary based on the nature of the

message.

Publish / Subscribe Messaging (One to Many)


Topics can be grouped into hierarchies, for example:

• A house‟s smart meter publishes on:

• <country>/<region>/<town>/<postcode>/<house>/energyConsumption

• <country>/<region>/<town>/<postcode>/<house>/solarEnergy

• <country>/<region>/<town>/<postcode>/<house>/alarmState

• And subscribes to:

• <country>/<region>/<town>/<postcode>/<house>/thermostat/setTemp

A subscriber can subscribe using wildcards:

• Single-level wildcards “+” can appear anywhere in the topic string

• Multi-level wildcards “#” must appear at the end of the string

• For example

• UK/Hants/Hursley/+/+/energyConsumption

• Energy consumption for all houses in Hursley

The system can retain the latest message published on a topic, for use by new subscribers

Included in IBM WebSphere MQ

v7.1 / 7.5 and MessageSight

• Open published spec designed for the

world of “devices”• MQTT client code (C and Java) donated

to the Eclipse "Paho" M2M project

• Simple / minimal pub/sub messaging

semantics• Asynchronous (“push”) delivery

• Simple set of verbs -- connect, publish,

subscribe and disconnect.

• Minimized on-the-wire format• Smallest possible packet size is 2 bytes

• No application message headers

• Reduced complexity/footprint• Clients: C=50Kb; Java=100Kb

• Three qualities of service:0 – at most once delivery

1 – assured delivery but may be duplicated

2 – once and once only delivery

• In-built constructs to support loss of

contact between client and server.• “Last will and testament” to publish a

message if the client goes offline.

• Stateful “roll-forward” semantics and

“durable” subscriptions.
