Abstract

Modeling the Internet infrastructure is a challenging endeavor. Complex interactions between protocols, increasing traffic volumes and the irregular structure of the Internet lead to demanding requirements for the simulation developer. These requirements include implementation detail, memory efficiency and scalability, among others. We introduce a simulation model of the Border Gateway Protocol that we call BGP++, which is built on the popular ns-2 simulation environment. A novel development approach is presented that incorporates the public domain routing software GNU Zebra in the simulator. Most of the original software functionality is retained, while the transition to the simulation environment required a manageable amount of effort. Moreover, the discussed design inherits much of the maturity of the original software, since the later is only minimally modified. We analyze BGP++ features and highlight its potential to provide significant aid in BGP research and modeling.

创建真实的BGP模型

对Internet基础设施进行建模是一项具有挑战性的工作。协议之间复杂的交互、不断增加的流量和Internet的不规则结构对仿真开发人员提出了苛刻的要求。这些需求包括实现细节、内存效率和可伸缩性等。本文介绍了一种边界网关协议的仿真模型，我们称之为BGP++，它建立在流行的ns-2仿真环境之上。提出了一种新的开发方法，将公共领域路由软件GNU Zebra集成到模拟器中。大多数原始软件功能被保留，而过渡到模拟环境需要一个可管理的工作量。此外，所讨论的设计继承了原始软件的许多成熟度，因为后者只进行了最低限度的修改。我们分析了BGP++的特性，并强调了它在BGP研究和建模中提供重要帮助的潜力。
