Parlay Gateway体系结构的多视点研究

Research on Parlay Gateway architecture with mutil-view of model

基于“4+1”多视点模型描述了ParlayGateway体系结构的全貌。逻辑视点模型清晰地描述了ParlayGateway的概念模型,分析了该逻辑功能实体涉及的主要角色及其逻辑功能;将面向对象、构件化、低耦合的思想用于开发视点模型,展示了它的标准接口功能、协议适配功能等主要内容;在进程、物理视点模型中,描述了它的并发、冗余、安全、一致性等各种非功能属性,部署视图模型专门讨论网关和网络实体的连接问题;在场景视图中,将多个视点的研究有机地结合起来,全面展示了SCF注册、AS发现、Framework认证、第三方应用执行的整个过程。

Since the shortage of practical research on Parlay Gateway architecture, a comprehensive view of it was described fully and clearly based on “ 4＋1 ” view model .The logic view captured the conception and analyzed main roles and logic entities involved in Parlay Gateway. Using the thoughts of object-oriented, component-based,loosely-coupled, the development view model described the static organization of main functional component such as standard SCF API, protocol adaptation etc. The process and the physical view took into account various nonfunctional aspects of concurrency, redundancy, security and consistency. The deployment view discussed issues especially of its interconnection to the existing network. The scenario view, which combined with the others view organically, described some typical mechanisms of SCF registering, AS discovering, Framework authenticating and the third party application executing.
