PLDA：AS级的Internet拓扑生成算法

Internet拓扑建模是进行Internet研究的基础。PLOD是一种AS级的Internet拓扑生成算法，但PLOD算法不能保证生成拓扑图的连通性，且存在“出度贷款过剩”现象。对PLOD算法进行改进，提出PLDA算法。在AS节点连接时添加连通性检测，并对出度大的AS节点实行优先连接，较好地解决PLOD算法存在的问题。实验结果表明，PLDA算法是有效可行的。

PLDA: AS-level Internet Topology Generating Algorithm

Internet topology modeling is the foundation of Internet performance research.Power-Law Out-Degree(PLOD) algorithm is an AS-level Internet topology generating algorithm.But it cannot guarantee the connectivity of the topology and has the credit overstock problem.Based on PLOD,Power-Law Degree Algorithm(PLDA) is proposed.It adds the connectivity check and gives link preference to nodes which have more out-degrees.PLDA ensures the connectivity and mitigates the credit overstock problem.Experimental results in...
