2 Or: The End To Protocols As We Know Them Dr. Hellmuth Broda Chief Technologist Europe, Middle East & Africa Member, Sun Vision Council Sun Microsystems, Inc. Hellmuth.Broda@Sun.COM Jini™ Technology Simply connect. A Computing History Disk Centered Computing Microprocessor Age Network Age CPU Disk Disk-oriented OS Multi-chip CPUs Systems on a board Inexpensive disks Embedded devices Personal devices Network services Service Age 1950’s 1980’s Mid-1990’s Jini Communities Java™ Technology Services 2000 History of Jini Sun R&D project (Bill Joy, and Jim Waldo with Ann Wollrath, theinventor/designer of RMI, Ken Arnold, the designer of JavaSpaces, and Bob Schleifer, designer of Lookup/Discovery). Mid-1960‘s: David Gelernter (Yale) developed a programming language called LINDA (http://www.cs.yale.edu/HTML/YALE/CS/Linda/linda.html) Linda and JavaSpaces JavaSpaces: implementation of the ideas behind LINDA but greater use of recent advances in object technology, namely Java. ``The work at Yale focused mainly on data, but today we can just move objects in and out of JavaSpaces [. . .] JavaSpaces is essentially a facility for communicating tasks out and bringing jobs back'' (James Gosling). Drivers of Transition to the Networked Age Increased network bandwidth Bandwidth is pervasive — increase in the number of wired/ wireless networks Inexpensive processing power (systems on a chip) Software based on objects and agents Ten Megatrends Services – not applications Wireless > Internet > PC markets eMarketPlaces Content => service => device Network centric development Focus on business logic and accessibility Capacity planning is an oxymoron Supply chain integration and auctioning as examples of new business model Everything is mission critical Simplicity!

How can we interoperate without a PhD in networking? The Quest For Connectivity Jini technology, based on Java technology, enables digital services to simply connect together. What is Jini? Software layer (48kB) to describe services to the net Runs on all Java Virtual Machines (JVM) on any device (from mainframe to toaster) Only the Front-End of the service is transmitted---Distributed Computing End of all Protocols as we know them Resilience: does not assume that networks always work Jini Technology Enables You to Simply Connect Instant On Plug it in and it just works, no fuss, hassle free Impromptu community Create your personal community of devices and services — at home, in the office, or on the road — and interact with other communities quickly and easily Resilient Your Jini community maintains itself & adapts to change Your Jini community is always available The Service Age allows the system to be more tolerant and redundant Special delivery Services are available on demand Introduces Simple, Powerful New Concepts Simply Connect to Anyone, Anywhere, Anytime on Anything Services Home Small Office Email Voice Financial Telephony Entertainment Corporate Data Center Mobile Jini Technology Signals the Start of the Service Age Creates New Business Opportunities Device Manufactures Storage, peripherals, PDAs, CPUs, etc. An Easier Way to Interact with the Digital World Consumers Phone VCR TV Service Providers Search Engines Portals Telecommunications A Simple Way to Develop & Deploy New Services Create and Deploy New Applications Developers Tools Management software The Philosophy Behind Jini Technology Simplicity: Less is more Small code base No complicated OS Everything is an object Use RMI to extend objects to remote resources Self-healing networks System restores state after failures Resilience Community Easy access to Jini technology Anyone can join the Jini community Everything is an object Distributed system is just a distributed program Java Class Hierarchy describes devices/services Mobile Code via Remote Method Invocation Leasing and distributed garbage collection provides self-healing Individual devices/services can be simple, don’t require a Java Virtual Machine Services available on demand Jini Technology Principles Jini Technology Java + Jini Technology Infrastructure Programming Model Services Java APIs JavaBeans Components etc... Discovery & Join Distributed Security Lookup Service Java Virtual Machine RMI Java Security JNDI Enterprise JavaBeans Components JTS etc... Leasing Transactions Distributed Events Printing Transaction Manager JavaSpaces™ Service Base Java Technology Let objects find each other,... …add simple APIs for remote objects and basic distributed computing,... …then everything else is a service. Discover (find) and join a community of Jini technology-enabled devices Advertise its capabilities Provide any required software and attributes – no drivers required Requires only one Java Virtual Machine on the network Send out a multicast packet with reference to yourself Receive a RMI reference to the Lookup Service Innovative Solution for Finding the Place to Start in an Unknown Network Jini Technology Infrastructure: Discovery & Join Repository of available services Stores service as extensible set of Java application objects ID, interface, GUI’s, attributes, drivers... Service objects downloaded as required May be federated with other lookup services Lookup Service interface Registration, Access, Search, Removal Binds the Jini Community Together Jini Technology Infrastructure: Lookup Service Basic communication mechanism between components in a Jini system Secure ability to find, activate, and garbage collect objects Allows data as well as code to be passed from object to object Jini Technology Infrastructure: Moving Code Uses Java Technology Remote Method Invocation (RMI) Protocol for managing resources using a renewable, duration based model Contract between objects Resources can be shared or nonshared Provides Method of Managing Resources in a Networked Environment Jini Technology Programming Model: Leasing Designed for distributed object conversations Light weight, object-oriented Supports subset levels of ACID properties Supports nested transactions Uses leasing protocol Enables Distributed Entities to Cooperate Jini Technology Programming Model: Transactions Extends Java platform event model to allow it to work in a distributed network Register interest, receive notification Allows for easy use of event managers Can use numerous distributed delivery models: Push, pull, filter ... Uses leasing protocol Addresses Peculiarities of Messages in the Networked Environment Jini Technology Programming Model: Distributed Events Jini distributed security adds notion of principal and access control lists Jini services are accessed on behalf of a principle which traces back to a particular user/device Access to a service depends on the access control list associated with that service Builds on the Java Virtual Machine Jini Technology Infrastructure: Distributed Security Shared, “dynamic memory” for networked Java Virtual Machines Helps federate the network of Java Virtual Machines Provides simple, dynamic object persistence Facilitates alternative messaging patterns async, store and forward, routed, filtered... Service interface of JavaSpaces technology Writing, finding, reading, removing, event May be Used to Implement a Large Number of Distributed Computing Patterns Jini Technology Services: JavaSpaces™ Technology Jini™, how does it work?
