摘要： 增强节点的自组织与协调能力是引导互联网健康发展的重要途径。该文通过分析域间路由系统的结构特点，提出AS联盟的概念。它是一组按照域间路由结构特点自组织的AS节点。基于AS联盟的域间路由协议安全扩展机制可以避免集中式控制的不利影响，且具有较低的证书管理代价，而稳定性扩展机制则能有效降低一定范围内的路由振荡。

Abstract: Improving the ability of self-organization and interoperability is the important way to make the Internet develop well. This paper presents the notion of AS Alliance by analyzing the structure character of inter-domain routing system, which is a group of self-organized AS nodes. The security extended mechanism for inter-domain routing protocol based on AS Alliance can avoid the impact of center-control, and has lower cost of certificate management. Moreover, the stability enhanced mechanism can effectively decrease routing vibration in some extent.

Key words: inter-domain routing, AS Alliance, routing security, self-organization
