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可编程路由器平台上开发的协议组件。软件环境已经建立在一个基于组件的软件体系结构，称为自主组件架构（ACA），部署了一个消息传递，独立的执行模型，以实现软件IC的概念。在ACA之上，一个基于分组的网络建模框架，称为可扩展互联框架（EIF），已奠定了去？新的通用网络组件足够通用，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）完整的一套基本的互联网协议在互联网上最好的电子商务？分类服务、综合服务和分类服务。增强服务体系结构。生成的代码，沿着脚本框架，构成了一个称为JavaSim的网络模拟环境。

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-programmable router platform. The software environment has been built upon a component-based software architecture, called autonomous component architecture (ACA), that deploys a message-passing, independent execution model to realize the notion of software IC. On top of ACA, a packet-based network modeling framework, called extensible internetworking framework (EIF), has been laid to de?ne generic network components that are general enough to accommodate future technology advances. To demonstrate the use of ACA and EIF, we have implemented in Java both ACA and EIF, and an (almost) complete suite of essential Internet protocols in the Internet best-e?ort service, integrated services, and di?erentiated services architectures. The resulting code, along with a scripting framework, constitutes a network simulation environment called JavaSim.
