摘要
网络发展到面向应用的阶段 ,传统面向系统互连的网络体系结构已经不能满足各种以高性能为评价指标的网络应用需求 .通过研究计算机网络体系结构发展的历史 ,吸收了软件体系结构研究的成果 ,提出了一种基于交互的网络体系结构框架模型 (FINA) .FINA从宏观网络分层结构、构件化框架模型、以及网络构件及其交互模板 3个抽象级别描述网络体系结构 ,既保留了传统网络对等层交互的开放互连结构 ,又引入了现代网络相邻层交互的可定制结构 .通过运用 FINA描述和分析了传统网络及可编程网络体系结构 ,说明了 FINA适合于描述和评价过去以及现在具有灵活服务定制要求的高性能网络体系结构 .
As network technology has developed into the application oriented stage, the traditional interconnection oriented network architecture can no longer meet the requirement of network applications evaluated by high performance. By researching on the history of network architecture development and adopting the results of software architecture researches, a framework of interaction based network architecture (FINA) is proposed in this paper. FINA describes network architecture in three abstract levels: general network hierarchical structure, component based framework, and template of components and their interactions. It not only still has the open structure of peer to peer interactions in traditional network architecture, but also introduces the customized structure of inter layers interactions in modern network architecture. It is shown that FINA is suitable for describing and evaluating the traditional network and high performance network with flexible service customization requirements by applying it to describing and analyzing the traditional and programmable network architecture.
