Session 24202
Overall Presentation Goal
Learn how to architect and build Service-to-Service (S2S) environments using RMI, Jini™,Rio, Java™ Servlet, and JDBC™
technologies
![Page 3: FIPER: The Federated S2S Environmentsorcersoft.org/publications/papers/2420.pdf• Jini technology-based Service Beans are instantiated by Cybernodes – Cybernodes run on computational](https://reader035.fdocuments.us/reader035/viewer/2022071609/6147383eafbe1968d379ea93/html5/thumbnails/3.jpg)
Session 24203
Learning Objectives
• As a result of this presentation, you will be able to:– Design S2S environments using RMI, Jini™
and Rio technologies– Recognize network-centric vs. server-centric
frameworks– Understand the job/task/context/method
paradigm– Recommend a distributed
megaprogramming system

Session 242013
Applying OO Techniques to the Network
• Service activity is a special object of type: Exertion
• Exertions are executed by network objects/service providers of type: Servicer
• Service providers form P2P environment• Service is requested by calling the method: service(Exertion)• Service providers are identified by a Java™
technology type with methods: public ServiceContext selector(ServiceContext)
![Page 14: FIPER: The Federated S2S Environmentsorcersoft.org/publications/papers/2420.pdf• Jini technology-based Service Beans are instantiated by Cybernodes – Cybernodes run on computational](https://reader035.fdocuments.us/reader035/viewer/2022071609/6147383eafbe1968d379ea93/html5/thumbnails/14.jpg)

Jini™ Network Technology Service BeansRio• Jini™ technology-based Service Beans
(“JSBs”) are the fundamental domain specific computational entities on the network
• Are provisionable based on their QoSattribute
• Jini technology-based Service Beans are instantiated by Cybernodes– Cybernodes run on computational resources– Cybernodes can contain multiple
service beans

Summary (CNb)3
• Service Centricity – everything is a service, each represented as
an object on the network identified by type
• Network Centricity– services discover each other– the service is the network (N-1, 1-1,
1-N, S-N)
• Web Centricity– Interportals/Extraportals to services
with thin web clients (applets/servlets)

Conclusion
• Jini™ and Rio technologies enable federated S2S, platform independent, real world megaprogramming environments.
• A FIPER job is a distributed megaapplication executed in a federated S2S environment.
