Abstract

This paper presents a framework for developing and executing Java routing protocol implementations within the network simulator NS2. NS2 provides extensive support for developing C++ routing protocols, but has no Java support. In this paper, we describe extensions we have made to the AgentJ toolkit that enable routing protocols to be integrated directly into NS2 without needing to extend the internals of NS2 for each new protocol. The framework defines a reusable AgentJ routing protocol definition that can be used to register new protocols dynamically from within Java code. The actual routing protocol can then leverage the AgentJ toolkit for executing unmodified Java applications in NS2. By means of aspect-oriented byte-code rewriting, AgentJ allows preexisting Java routing protocols, which run on the Internet, to run unmodified within NS2. This powerful system also helps researchers to both understand high-level and algorithmic properties of a given Java routing protocol through the analysis of an NS2 simulation and to rapidly develop and debug new routing protocols through prototyping and experimentation.

支持Java NS2路由协议的开发框架

本文提出了一个在网络模拟器NS2中开发和执行Java路由协议实现的框架。NS2为开发c++路由协议提供了广泛的支持，但没有Java支持。在本文中，我们描述了我们对AgentJ工具包所做的扩展，这些扩展使路由协议能够直接集成到NS2中，而无需为每个新协议扩展NS2的内部。该框架定义了一个可重用的AgentJ路由协议定义，可用于从Java代码中动态注册新协议。然后，实际的路由协议可以利用AgentJ工具包在NS2中执行未修改的Java应用程序。通过面向方面的字节码重写，AgentJ允许在Internet上运行的预先存在的Java路由协议在NS2中不加修改地运行。这个强大的系统还可以帮助研究人员通过NS2模拟分析了解给定Java路由协议的高级和算法属性，并通过原型和实验快速开发和调试新的路由协议。
