Abstract

Service-Oriented Architecture is an architectural model that aims to enhance the efficiency, agility, and productivity of an enterprise by structuring services in terms of services compositions, which can be executed either synchronously or asynchronously. Such architectures should meet the main dependability requirements (e.g. high availability, high reliability). The objective of this work is to describe a software infrastructure, called WSCA-DRIP, that operates in the communication between a web service's clients and the web service itself, in order to implement fault tolerance techniques that make effective use of exception handling of undependable existing services. Also, the proposed solution lies in systems structuring in terms of a collaborative realization of a given function by composed web services and a fault tolerance strategy by means of cooperative exception handling. Finally, the WSCA-DRIP infrastructure will be designed to be remotely accessible via web services technology, so that it can be easily reused during the implementation of different web services-based service oriented architectures.

WSCA-DRIP: Web服务组合操作的基础设施

面向服务的体系结构是一种体系结构模型，旨在通过根据服务组合构建服务来提高企业的效率、敏捷性和生产力，服务组合可以同步执行，也可以异步执行。这样的架构应该满足主要的可靠性要求(例如高可用性、高可靠性)。这项工作的目标是描述一个软件基础设施，称为WSCA-DRIP，它在web服务的客户端和web服务本身之间的通信中运行，以便实现容错技术，有效地利用对不可靠的现有服务的异常处理。此外，该解决方案还包括通过组合web服务协作实现给定功能的系统结构和通过协作异常处理的容错策略。最后，WSCA-DRIP基础设施将被设计成可以通过web服务技术远程访问，以便在实现不同的基于web服务的面向服务体系结构期间可以轻松地重用。
