Distributed Planetary Object Name Service: Issues and Design Principles

چکیده
The ONS is a central lookup service used in the EPCglobal network for retrieving the location of information about a specific EPC. This centralized solution lacks scalability and fault tolerance. We present the design principles of a distributed solution for ONS lookup service. In distributed systems, the problem of providing a scalable location service requires a dynamic mechanism to associate identification and location. We show that the use of Distributed Hash Tables (DHT) is a good candidate for distributing as it provides such a mechanism. We then outline how to adapt the DHT principles (operations on objects or nodes) to the ONS distribution problem.

Cette solution supporte mal le passage à l’échelle et est peu tolérante aux pannes. Dans ce rapport, nous introduisons les principes d’une solution distribuée pour le service ONS basé sur l’utilisation de tables de hachage distribuées.

Service Design in Distributed Intelligent Networks
This paper identifies issues related to the service design process in an advanced distributed Intelligent Network environment. Starting from the fundamental definition of the Intelligent Network Conceptual Model (INCM) it highlights its basic, intrinsic properties and underlying assumptions. In an effort to enhance the traditional IN architecture with distributed, object oriented features, it i...
متن کاملCosNamingFT - A Fault-Tolerant CORBA Naming Service
This paper describes the design and implementation of a fault-tolerant CORBA naming service CosNamingFT. Every CORBA object is accessed through its Interoperable Object Reference (IOR), which is registered with the CORBA name service. The name service therefore is a critical gateway to all objects in a distributed system; to avoid having a single point of failure, the name service should be mad...

متن کاملAdaptive Resource Management of a Virtual Call Center Using a Peer-to-Peer Approach
As the number and diversity of end user environments increase, services should be able to dynamically adapt to available resources in a given environment. In this paper, we present the concepts of migratory services and peer-to-peer connections as the means of facilitating adaptive service and resource management in distributed and heterogeneous environments. Our approach has been realized usin...
