| 摘 要： | 将P2P引入到高速入侵检测中,在探测器网络中进行负载均衡,分流器只负责将高速流量尽可能均匀地分发到各探测器,从而减轻前端分流器的负担.提出基于P2P的均匀哈希分流算法,考虑到探测器网络的规模,将IP地址和端口号划分成8位比特串,对这些8比特串进行异或和移位的哈希运算.理论分析和对比实验结果表明,该算法位熵最大,具有更好的均匀性. |

| Abstract: | P2P is introduced into high-speed intrusion detection for load balancing in sensor network in this paper.By this means,traffic splitter only needs to deliver the high-speed network flow to sensors uniformly to the best of its abilities.As a result it reduces the load of splitter and a uniform hash algorithm based on P2P is presented. Considering the scale of network sensors,the IP and port address are divided to 8-bit substring in this algorithm,and then the 8-bit string should be calculated according to ex... |
