安全网关控制信息采集是天地一体化网络中的一种重要安全感知技术,传统的等时间间隔采集策略存在网络带宽浪费、数据大量冗余、采集节点数据采集量过大、传输次数过多等问题,针对这些问题,提出了一种基于旋转门算法的安全网关控制信息采集策略,该策略通过改进的旋转门算法分析判断安全网关控制信息(如网关流量、CPU利用率等)的变化幅度,自适应调整安全网关控制信息采集间隔。实验结果表明,该策略与传统等时间间隔采集策略相比,能在保证数据准确率的情况下,减少数据采集次数和数据传输次数,有效降低网络开销,提高数据采集效率。
Acquisition the control information of security gateway is an important security awareness method in the space and earth integrated network
but the traditional equal interval time data method acquisition has problems
such as waste of network bandwidth
a large amount of data redundancy
excessive data collection of acquisition node and excessive transmission times.In order to solve these problems
a data acquisition strategy based on improved swing door trending algorithm was proposed
which analyzed and improved swing door trending algorithm to determine the control information of security gateway such as the rangeability of gateway traffic and CPU utilization
and to adjust the data acquisition interval adaptively.The experimental results show that compared with the traditional equal interval time data method acquisition
under the condition of ensuring the data accuracy
the proposed strategy can lower the times of data acquisition and transmission
effectively reduce network overhead and improve data acquisition efficiency.
