An Efficient Implementation of Decoupled Communication in Distributed Environments
نویسنده
چکیده
Decoupled communication has proven to be a powerful paradigm for the development of applications in the context of open distributed environments. We hav e developed the Object Space approach which integrates that communication style with object-oriented techniques. It allows encapsulation of protocols for interactions in a distributed application into classes, thus providing a new lev el of abstraction. Here we describe how decoupled communication as supported by the Object Space may be efficiently implemented in distributed environments. We start with a naive prototypical implementation and develop a more efficient fault tolerant solution. This implementation is itself distributed. It runs on top of UNIX systems connected by a LAN.

Objects, Replication and Decoupled Communication in Distributed Environments
Overview • The Object Space Approach: object-oriented essentials and decoupled communication. • Example: a distributed time service. • A distributed protoypical implementation of Object Space. • Employing replication and optimistic asynchrony: a more efficient implementation.
متن کاملA Robust Distributed Estimation Algorithm under Alpha-Stable Noise Condition
Robust adaptive estimation of unknown parameter has been an important issue in recent years for reliable operation in the distributed networks. The conventional adaptive estimation algorithms that rely on mean square error (MSE) criterion exhibit good performance in the presence of Gaussian noise, but their performance drastically decreases under impulsive noise. In this paper, we propose a rob...
متن کاملProvably secure and efficient identity-based key agreement protocol for independent PKGs using ECC
Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...
متن کاملAsynchonrous Notifications Among Distributed Objects
Distributed object systems typically support synchronous requests from one distributed object to another. Often, a more decoupled style of communication among distributed objects is appropriate. We describe an object service called event channel that decouples distributed object communication. We describe SunSoft’s implementation of the event channel and illustrate its use in a stock trading ap...
متن کاملSurvey on Security Methods in Publish / Subscribe System
Publish/subscribe (pub/sub) system is an emerging communication paradigm that offers efficient and decoupled information dissemination in distributed environments. Decoupling increases the privacy of each participant. Publishers generate the flow of information as publications and subscribers interests may be expressed as subscriptions. Basic security mechanisms such as authentication and confi...
