Shared Object Management on Java with Dynamic Replication Control Strategy

概要

論文の詳細を見る
Nowadays, shared objects are very common in distributed programming. In fact, a distributed system consists of a set of computers located in different sites connected by means of a communication network. The resources may be completely or partially replicated, or partitioned. The main purpose of a distributed system is to give low cost availability of the resources of the system by getting access locally and providing isolation against failures of single components. As matter of fact, actual shared object systems are facing problems such as communication latency, partition failures, inconsistency of data and so forth. We attempt to tackle these problems among servers and processors by duplicating data dynamically. In our system, shared objects are implemented using object-oriented programming since object-oriented systems allow information to be encapsulated. They also make programming transparent and reduce development time. Besides, generic data can be created at the different levels of inheritance. Our shared object management is created in JAVA because it is a platform-independent language and also allows programs to run on several OS. Besides, multi-threading is required to make requests from processors to work concurrently or in parallel on each server. It is an object-oriented language and allows networking development as well.
