NGS: Collaborative Research: A Component-based Software Environment for Simulation, Emulation, and Synthesis of Network Protocols in Next Generation Software

在这个项目中，我们建议设计，实现和评估一个基于组件的软件环境，用于系统地模拟和仿真网络协议，并用于各种目标网络体系结构。我们还将探讨使用软件programmablerouter平台上开发的协议组件。软件环境建立在一个基于构件的软件体系结构之上，称为多构件体系结构（ACA），它部署了一个消息传递的、独立的执行模型来实现软件IC的概念。在ACA之上，一个基于分组的网络建模框架，称为可扩展的互联网络框架（EIF），已奠定了去？新的通用网络组件，足以适应未来的技术进步。为了演示ACA和EIF的使用，我们已经在Java中实现了ACA和EIF，以及（几乎）完整的互联网最佳电子商务中的基本互联网协议套件。ortservice、integrated services和di？增强服务体系结构。结果代码，沿着脚本框架，构成了一个称为JavaSim的网络仿真环境。

In this project, we propose to design, implement, and evaluate a component-based software environment forsimulating and emulating network protocols in a systematic manner, and for a wide variety of target networkarchitectures. We will also explore the use of the developed protocol components on a software-programmablerouter platform. The software environment has been built upon a component-based software architecture, calledautonomous component architecture (ACA), that deploys a message-passing, independent execution model torealize the notion of software IC. On top of ACA, a packet-based network modeling framework, called extensibleinternetworking framework (EIF), has been laid to de?ne generic network components that are general enoughto accommodate future technology advances. To demonstrate the use of ACA and EIF, we have implemented inJava both ACA and EIF, and an (almost) complete suite of essential Internet protocols in the Internet best-e?ortservice, integrated services, and di?erentiated services architectures. The resulting code, along with a scriptingframework, constitutes a network simulation environment called JavaSim.
