| 摘 要： | 网络弹性研究的是网络在节点失效或被有意攻击下所表现出来的特征。分析Gnutella网络的网络弹性，包括对于随机攻击的容错性和对于选择性攻击的抗攻击性，并与ER模型和EBA模型进行了对比。Gnutella网络对于随机攻击具有很好的容错性，但是对于选择性攻击却显得脆弱。最后对网络弹性进行了理论分析，给出了网络在出现最大集团临界点之前的平均集团大小的公式解。

| Abstract: | Study on network resilience is about the characteristics of robustness and vulnerability in random failing of nodes and intended attacking on nodes. The resilience of Gnutella network was analyzed, and the result was compared with that of ER and EBA models. The result shows that Gnutella network exhibits very good fault-tolerance characteristic, but is very fragile under intended attacks. Finally,the network resilience was analyzed theoretically,and a closed-form solution for average size of clusters was reached before the largest cluster of network appeared. |
