Web服务及其在Parlay接口中的应用

电信网与Internet走向融合，而Parlay接口与Web服务作为各自领域开放技术的代表，也开始了互相结合。Web服务是一种基于可扩展标记语言（XML）、面向消息的分布式计算技术，与公共对象请求代理体系结构（CORBA）等分布式对象技术相比，在Internet范围内的互操作性更好。Web服务是实现面向服务体系结构（SOA）的最佳候选技术之一。基于Web服务的Parlay接口包括Parlay Web服务和Parlay X。其中，Parlay Web服务模拟面向对象的Parlay应用编程接口（API）定义，Parlay X的设计遵循Web服务面向消息的技术发展思路。基于Web服务的Parlay接口技术为构建电信网和Internet融合环境下的统一业务体系提供了基础。

Web Services and Their Applications in Parlay Interface

Along with the convergence of telecommunication networks and the Internet, the Parlay interface and Web Services, as typical open technologies in their own field, are developing towards convergence too. Web Services is an XML-based message-oriented distributed computing technology. It provides better interoperability while compared with the Common Object Request Broker Architecture (CORBA) and other object-oriented distributed computing technologies. And it is also one of the best technologies for implementing Service-Oriented Architecture (SOA). The Parlay interface based on Web Services includes Parlay Web Services and Parlay X. Parlay Web services simulate object-oriented Parlay Application Programming Interface (API) definitions and Parlay X follows the development trend of message-oriented Web services. The Parlay interface technology based on Web Services lays a foundation for building a unified service system in the converged environment of telecommunication networks and the Internet.
