近年来，互联网中的 BGP 融合问题得到了广泛的研究。通过形式化分析表明，BGP 收敛并不总是得到保证。当收敛时，基于主动测量的技术已确定收敛过程可能需要长达 15 分钟，同时还会导致间歇性数据包丢失/延迟。随着 BGP 增强功能被探索来解决这一收敛问题，受控模拟实验提供了最方便、最可行的机制来比较增强 BGP 程序与当前协议机制的功效。由于收敛行为可能会受到网络拓扑的显着影响，因此在此类受控仿真中需要使用类似大型互联网的拓扑。在本文中，我们提出了实现大规模 BGP 仿真环境的第一步，以推理当前的 BGP 过程并评估 BGP 协议增强的功效。
BGP convergence issues in the Internet have been extensively studied in recent years. It has been shown through formal analysis that BGP convergence is not always guaranteed. When it does converge, active measurement based techniques have determined that the convergence process may take upto 15 minutes while also causing intermittent packet loss/latency. As BGP enhancements are explored to address this convergence problem, controlled simulation experiments offer the most convenient and feasible mechanism to compare the efficacy of enhanced BGP procedures with respect to the current protocol mechanisms. Since the convergence behavior can be significantly influenced by network topology, it is desirable to use large Internet like topologies in such controlled simulations.In this paper, we present first steps towards realizing a large scale BGP simulation environment for reasoning about current BGP procedures and also for evaluating the efficacy of BGP protocol enhancements.
