This document provides an overview of Jini Network Technology. It discusses why Jini was created due to challenges with distributed computing. Jini allows devices to dynamically join and leave a network without configuration. It uses simple interfaces and protocols to enable spontaneous networks of software services. The key components of the Jini architecture are services, clients, and lookup services that help clients discover and utilize services. Jini provides benefits like resiliency to network changes and easy integration of new components.

- 1. JINI Network Technology Presented By: K.Keerthi 093Q1A0529
- 2. Outline Why JINI? What is JINI? Purpose of JINI? JINI Architecture Overview Jini Service Oriented Architecture Jini Players Jini Process Merits Unique Benefits Future Work Conclusion
- 3. WHY JINI? Distributing computing is more difficult than local computing because of: Network Latency Concurrency Issues Memory Management Inevitable partial failure
- 4. What is JINI? •The jini technology makes a network more dynamic •It provides mechanism for devices to join and detach from network dynamically without the need for configuring each device •Jini is also called “Apache River” •Jini addresses the problems of distributed computing using a set of simple interfaces and protocols •Jini enables spontaneous network of software services to assemble into working groups of objects or Federations • Jini builds on the Java 2 Platforms • Jini enables self healing when one or more devices are removed from the federations •Jini is useful for hardware as well as software services
- 5. Purpose of JINI Enabling users to share services or resources over a network Providing users easy access to the resources anywhere on the network Simplifying the task of building , maintaining and altering a Network of devices , software and users.
- 7. JINI Service Oriented Architecture The basic networks elements in the Jini architecture related to this issue are: Lookup Service Service Proxy Client
- 8. JINI Players There are three main players : 1: A Service, such as printer,scanner,storag 2: a Client, which e device,a software would like to make 3:a LookUp, service service etc use of the service (LUS)- service Locator
- 9. JINI Process (Discover) (Discover) (lookup) (join)
- 10. Discover y discovery is the Jini process of adding a LOOKUP SERVICE service to a Jini system. CLIENT SERVICE PROVIDER
- 11. Join Service object for LOOKUP SERVICE the service is loaded into the lookup service CLIENT SERVICE PROVIDER
- 12. Lookup LOOKUP SERVICE A client requests a service by its type and/or its attributes. A copy of the proxy is moved to the client CLIENT SERVICE PROVIDER
- 13. Merits •Dynamically builders can be loaded with various kinds of Factory settings •Support for different Display Technologies •Stub is Light weight and does not carry any extra UI classes •Adding support for new UI tech by simply adding new builders at service end
- 14. Unique Benefits Resiliency - Networks readily adapt to changes in the computing Environment Integration - Allows fast , easy incorporation of Legacy , current and future network components Licensing - jini network technology is available free of charge With an evergreen license.
- 15. Future Work Identifying and refining the UI patterns Security in jini: Who can access services? Authentication Who can invoke what services? Authorization
- 16. Conclusion The overall goal is to turn the network into a flexible , easily administered tool on which resources can be found by human and computational clients….we can use Jini technology to create technology systems that are scalable,evolvable and flexible in dynamic runtime environments in a multifaceted way….
