RFID – From Hype to Reality Dr. David Allais - invented one of the leading bar code symbologies of today: Commenting on RFID - “does everything, costs nothing and fits on the head of a pin” Matt SmithSenior Solutions Architect
Origins of RFID • Radio Frequency Identification • Basic technology is not new • Origins back in 40’s and 50’s with research into radio and radar • IFF for military aircraft • Commercial applications appear in 70’s • ID cards, animal identification, anti-theft

RFID Challenges • Technology isn’t perfect • Environmental factors can reduce read accuracy • Tags aren’t free • Cost of tags must be incorporated into products • Which standards to adopt • Different standards result in incompatible systems
RFID Rewards • Reduced labor costs • Reading process is simplified • Greater inventory accuracy • Always know what’s on shelf, in warehouse, … • Greater insight into business process • Track shipments from suppliers, to customers, … • Reduced shrinkage • Theft, accidental loss, expiration, …
Why RFID is often RFI “Don’t” • The business case often doesn’t stack-up • The costs of tags is still very high – for example, an RFID solution for Tesco would currently cost hundreds of millions for the tags alone • The data volumes generated are huge – we’ll discuss this later • Data mining must be done quickly and results distributed up and down the supply chain regardless of size of partners • Infrastructure supporting the system must be highly available – you can’t have hours worth of data “pending”! • Manageability is critical, but large scale RFID can’t be centralised – we’ll see why a bit later
A confluence of events • But… • The promise of RFID is enormous! • We are about to see a market break-through for a number of reasons • Tags – pioneering research by QinetiQ • Complex Metal Printing – print the tag! • Potential to achieve sub 3 pence tags • Data Distribution – Sonic delivers a Service Oriented Architecturefor RFID with world’s first Enterprise Service Bus • Storage – object databases come of age • Object Store uses a patented Cache-ForwardArchitecture to produce RFID Accelerator – more later
RFID – The Tags • Business case • Tags are too expensive • Passive = $0.5 for 1 million – Active = few dollars • This will change – ink print – QinetiQ Metal Printing • http://news.bbc.co.uk/1/hi/technology/3860229.stm • More innovation is needed – particularly from research teams, universities, and tech companies. • Or we can just order them in serious bulk • Gillette ordered 500 million tags in 2003 • Technical challenges once the tags are cheap enough: • What do you do with the data? • How do you perform parallel queries and correlation of data? • How do you move the data around? • Federated SOA appears to be the answer?
A quick quiz on the data volumes • Marks & Spenser • Have finished a successful trial with BT, and have just announced that they will go live with RFID across 53 stores by 2006 • Any idea what volume of data this will generate? • Tags reads per minute for this project? Tags per year – total? • Data Volume: • Need over 2000 tag reads per minute for this project • Will read over 500 million tags per year with other RFID projects in the pipeline • Will create dozens of down-stream events per tag read • Creating a data flows of well over 3.4 gigabytes per hour • Then you need to correlate and query this data!
RFID Challenges • Embarrassment of riches! • Lots of things to track in each sector: passengers, baggage, trolleys, vehicles, pallets, clothes, high value consignments, even trees! • Enormous potential for exponential growth in data volumes • Multiple uses cases and business benefits • Many challenges and pitfalls • Which are the quick-win projects to roll out first? • ALL generated data has a transactional function • Where do you keep it, and transact it? • Single, common infrastructure for all RFID projects • Architect an enterprise platform level

Distribution/Management Architecture • Fundamental Problems: • Centralised Event Collection will soon be overwhelmed • Central Discovery and Naming Service (ONS) does not scale • Need to distribute operations to reduce the flow of events at the middle…but… • De-centralised operations create new problems • Distributed Query Execution • Deployment, Configuration, Control, Monitoring • Synchronisation/Versioning • Autonomous Operation • Federation
Enterprise SOA Vision Benefits address long-standing IT dilemmas PORTAL SERVICE USER-DEFINED SERVICE BATCH SYSTEM BROAD-SCALE INTEROPERABILITY APPLICATION SERVER MODULARITY / REUSE RELATIONAL DATABASE INCREMENTAL DEPLOYMENT PROCESS SERVER FLEXIBILITY LEGACY APPLICATION What most people concentrate on are the endpointsBut the problem area is the “white-space” of SOA
Architectural Challenges of SOA platform • Dependability • Reliable, high-performance communications between services • High Availability = Business continuity • Security • Flexibility – this is a changing environment • Mechanism to orchestrate process through the network • Ability to dynamically re-configure services to new uses • Ability to normalise in-flight documents between services • Bridge multiple low-level middleware technologies • Reach and scale • Connect any resources regardless of where they are deployed • Scale from initial phases to arbitrarily large deployment • Retain visibility and control of distributed infrastructure
Enterprise SOA can help RFID Using an ESB to address this SOA “white-space” Using an ESB as the backbone PORTAL SERVICE USER-DEFINED SERVICE BATCH SYSTEM BROAD-SCALE INTEROPERABILITY APPLICATION SERVER MODULARITY / REUSE RELATIONAL DATABASE INCREMENTAL DEPLOYMENT PROCESS SERVER FLEXIBILITY HIGH AVAILABILITY LEGACY APPLICATION
The Purpose of an ESB Connect, Mediate and Control WITHOUT AN ESB WITH AN ESB Connect Control Mediate
Connect applications and services Multiple on-ramps, dependable communications • Connect old and new • Legacy applications, RDBMS • J2EE, .Net • Web services • B2B protocols • Link services and processes across the extended enterprise • Establish robust, scalable and secure communications Connect • Examples: • Securely link internal processes with those of business partners. • Portal integration All connected resources are first-class citizens
Mediate services Bridge and extend incompatible technologies • Reconcile system incompatibilities • Communication Protocol • Interaction model • Transform and enrich data • Map between data formats • Split, aggregate and enrich data • Provide flexible routing and process flow • Decoupled, event-driven services • Intelligent routing • Support stateful process management • Examples: • Aggregate data from multiple SAP systems • Regulation compliance logging Mediate Eliminate service interdependencies
Control service interaction Deploy, configure, manage • Dynamically configure, deploy and upgrade hosted services • Establish and alter process flows, routing, Quality of Service • Gain control and visibility over services and their interaction Control • Examples: • Deploy and upgrade 1000s of end-points from a single location. • Detect faults and diagnose problems in complex deployment. Configured, not coded
Global reach, global scalability • ESB spans clusters and security infrastructure to form federated environment • Bus topology obviates hub-and-spoke bottlenecks • Deploy what you need, where and when you need it End-to-end SOA
ESB helps the architecture, but not the data capture, storage and management
RFID: Why RDBMS is too Expensive • RFID Reader is able to read 200 Tags/sec. This results in a data volume 1000 times more than the data volume produced by traditional bar code scanner • Database systems (RDBMS) are able to process several hundreds of transactions per sec. • A non-relational object cache can processes more than 12,000 events per second and run queries at 1.1 million per second • (Reference hardware: Sun 450, 2 CPUs)
Object Cache + RFID + ESB • Combining these three technologies • Real-time in-memory event database dedicated to RFID • Object Store + Sonic Software = • First EPC-Database • Electronic Product Code • support of 96-bit EPC CodesClass 1 and Class 0 • EPC Version 1 Standard Compliance • http://www.objectstore.com/products/rfid/index.ssp

Solution: Event Absorption/Filtering • Horizontally distribute workload • Process/filter at the edge (hierarchical refinement) • Drive reference/summary info to the middle • What does this take? • High-speed (in-memory) event correlationwith transactional reliability & availability • Transactionally reliable transport fabric • Distributed Deployment & Management
Solution: Evolving/Multi-Vendor Standards • Evolving/incompatible RFID systems can be mediated to conform to internal canonical standards • Event cache service can house data and process that cannot be implemented inside a legacy application, thereby extending the legacy system into the RFID era • What does this take? • Internal design centre • Binds to a highly reliable/available ESB with automatic routing optimisation • Adapters isolate vendor-specific interfaces at the edge • Extensible caching of un-supported “alien” data in flight
10 Principles of RFID Data Management • Digest Data Close to the Source • Correlate Meaningful Events In Context • Buffer Event Streams • Cache Context • Federate Data Distribution in Real Time • Automate Deployment • Age RFID Data Gracefully • Use Code-less, Declarative Processes • Automate Exception Handling • Schema-less backbone/Global canonicals
