【摘要】：随着网络技术的发展,面对新的挑战,传统网络逐渐力不从心,软件定义网络(software-defined network,SDN)领衔的未来网络应运而生,随之而来的是各类网络测量技术纷纷针对未来网络发生演变,但拓扑结构测量在传统网络环境下的作用仍然不可忽视。在自治域级的网络拓扑中,每个自治域都可以简化为一个点,而用两点之间的连线表示自治域间的邻接关系。近年来有许多相关的研究展示了不同的拓扑发现算法。提出了一种简单高效的方法来推断自治域级的拓扑,利用在网络中部署高速采集器采集边界网关协议(border gateway protocol,BGP)路由器上的路由表以及BGP协议的更新信息来推断网络拓扑结构,并判定自治域的相关属性。实验证明了该方法能够达到预期效果,全面、准确地推断网络在自治域级的拓扑结构。
[Abstract]:With the development of network technology and new challenges, the traditional network is gradually unable to do its best. The future network led by software-defined Network Network (SDN) emerges as the times require, and then all kinds of network measurement technologies have evolved in response to the future network. However, the role of topology measurement in the traditional network environment can not be ignored. In the network topology of autonomous domains, each autonomous domain can be simplified as a point, and the adjacency between autonomous domains is represented by the connection between two points. In recent years, many related studies have shown different topology discovery algorithms. In this paper, a simple and efficient method is proposed to infer the topology of autonomous domain level. The network topology is inferred by deploying a high-speed collector in the network to collect the routing table on the boundary gateway protocol (border gateway protocol) router and the updated information of the protocol. The related attributes of autonomous domain are determined. The experimental results show that the proposed method can achieve the desired results and fully and accurately infer the topological structure of the network at the autonomous domain level.
