چکیده
The goal of the AQuA architecture is to provide adaptive fault tolerance to distributed applications by using commercial off-the-shelf hardware and operating systems. The AQuA architecture allows application programmers to request desired levels of dependability during applications’ runtimes. It also provides adaptive fault tolerance. In distributed systems, resources change dynamically, and different types of faults can occur anywhere and anytime. AQuA is designed to provide dependability for CORBA applications. It provides fault-tolerance mechanisms to ensure that a CORBA client can obtain reliable services, even if the CORBA server object that provides the desired services suffers from crash failures and value faults.

Acceptor-Connector An Object Creational Pattern for Connecting and Initializing Communication Services
The Acceptor-Connector design pattern decouples connection establishment and service initialization in a distributed system from the processing performed once a service is initialized. This decoupling is achieved with three components: acceptors, connectors, and service handlers. A connector actively establishes a connection with a remote acceptor component and initializes a service handler to ...
متن کاملAcceptor A Design Pattern for Passively Initializing Network Services
This article is part of a continuingseries that describes objectoriented techniques for developing reusable, extensible, and efficient communication software. The current topic examines the Acceptor pattern. This design pattern enables the tasks performed by network services to evolve independently of the strategies used to passively initialize the services. By decoupling service initialization...
متن کاملAcceptor and Connector Design Patterns for Initializing Communication Services
This paper describes the Connector and Acceptor patterns. The intent of these patterns is to decouple the active and passive connection roles, respectively, from the tasks a communication service performs once connections are established. Common examples of communication services that utilize these patterns include WWW browsers, WWW servers, object request brokers, and “superservers” that provi...
متن کاملAnalysis of the microstructural characteristics of FSW connection of A517 (B) steel and its relation to mechanical properties and corrosion behavior
The aim of this study was to evaluate the mechanical properties and corrosion behavior of friction stir welding (FSW) connection of A517 (B) steel plate. Mechanical properties and corrosion behavior of weld zone were evaluated after reaching to optimum FSW microstructure with the lowest martensite phase. Thus, after the identifying phase microstructure by SEM and XRD analysis, mechanical proper...
متن کاملA family of design patterns for flexibly configuring network services in distributed systems
This paper describes a family of design patterns that enhance the flexibility and extensibility of communication software by permitting network services to evolve independently of the strategies used to passively initialize the services. The paper makes three contributions to the study and development of configurable distributed systems. First, it identifies five orthogonal dimensions of passiv...
