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，以系统的方式模拟和仿真网络协议，并适用于各种目标网络架构。我们还将探讨开发的协议组件在软件可编程外部平台上的使用。软件环境建立在一个基于组件的软件体系结构上，称为自治组件体系结构（ACA），它部署了一个消息传递、独立执行模型来实现软件集成电路的概念。在ACA之上，一个基于分组的网络建模框架，称为可扩展互连网络框架（EIF），已经铺设好了。一种通用的网络组件，其通用性足以适应未来的技术进步。为了演示ACA和EIF的使用，我们在java中实现了ACA和EIF，并在Internet best-e？Ortservice、集成服务和di？差异化的服务体系结构。生成的代码与脚本框架一起构成了一个称为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-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.
