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，并针对各种目标网络体系结构进行模拟。我们还将探索在软件可编程的外部平台上使用开发的协议组件。软件环境建立在一个基于组件的软件体系结构之上，称为自主组件体系结构(ACA)，它部署了一个消息传递的独立执行模型来实现软件IC的概念。在ACA的基础上，建立了一个基于分组的网络建模框架，称为可扩展网际网络框架(EIF)，用于设计通用的网络组件，这些组件足够通用，足以适应未来的技术进步。为了演示ACA和EIF的使用，我们用Java实现了ACA和EIF，并在Internet最佳电子服务、集成服务和区分服务体系结构中实现了(几乎)完整的基本Internet协议集。生成的代码与脚本框架一起构成了一个名为Java Sim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-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.
