英文摘要：

The effective operation of the cloud computing network has a crucial relationship with the network invulnerability. On the basis of the cloud computing network, the load capacity model of the cloud computing network was constructed by ana- lyzing the invulnerability indicators. According to the influence of the different density nodes and different capacities on the cloud computing network invulnerability, the network capacity density is adjusted to obtain the best invulnerability of the cloud computing network. The improved algorithm proposed in this paper is compared with the traditional neural network algorithm, fuzzy probability algorithm and GM （ 1, N） algorithm by means of the simulation experiment. The experimental results show that the accuracy of the algorithm to estimate the cloud computing network invulnerability can reach up to 0.96, the maximum quantity of the connection nodes is 99, the algorithm is superior to the other three algorithms in the aspects of network applicability, damage rate and damage degree, has strong practicability, and can guarantee the security of the cloud computing network data in the transmission process.
