摘要
多路径高速以太网由不同的网络设备和系统组成,使得网络环境具有异构性。在异常入侵发生时,导致其故障难以被准确地识别,使得实现远程自恢复难度加大。为了确保以太网的正常运行,提出一种异常入侵下多路径高速以太网远程自恢复方法。构建多路径高速以太网异常入侵检测函数,干扰滤波处理入侵干扰信号,通过模糊约束自适应波束形成方法,检测滤波处理后的异常入侵信号特征,获取多路径高速以太网异常入侵检测结果。结合分布式恢复机制,组建树间快速标记交换路径(Label Switched Path,LSP),实现多路径高速以太网远程自恢复。实验结果证明,所提方法异常入侵检测率为93%,误检率最高仅为1%,且自恢复率可达98.12%,恢复时间短,具有良好的自恢复性能。
Multipath high-speed Ethernet is composed of different network devices and systems,making the network environment heterogeneous.When an abnormal intrusion occurs,it makes it difficult to accurately identify its faults,making it more difficult to achieve remote recovery.To ensure the normal operation of Ethernet,a multipath high-speed Ethernet remote recovery method under abnormal intrusion is proposed.Construct a multipath high-speed Ethernet anomaly intrusion detection function,process intrusion interference signals through interference filtering,and use fuzzy constrained adaptive beamforming method to detect the features of the filtered anomaly intrusion signals,obtaining the results of multipath high-speed Ethernet anomaly intrusion detection.Combining the distributed recovery mechanism,establish a Label Switched Path(LSP)between trees to achieve multi-path high-speed Ethernet remote recovery.The experimental results show that the proposed method has an anomaly intrusion detection rate of 93%,a maximum false detection rate of only 1%,and a recovery rate of 98.12%.The recovery time is short,and it has good recovery performance.
