摘要
Internet 是由几万个自治系统(Autonomy System,AS)组成的,不同 AS 的网络规模相差悬殊,在 Internet 中所处的地位也不相同,呈现出等级结构。在研究已有算法的基础上提出了基于 AS 关系的分层方法,该方法对 AS 有严格的层次控制,可以很好的体现 AS 间的等级关系,通过分层可以更好地了解 Internet 的网络拓扑、优化网络结构和网络接入。
The Internet is formed by tens of thousands of Autonomy Systems.The scale and importance are different from AS to AS and the AS is characteristic of different hierarchical level in the Internet.A new method to set AS Hierarchies is brought forward based on the research of existing ones.This method can control AS Hierarchies strictly and make it easier to understand intemet topolo- gy and improve intemet structure and access.
