Information acquisition strategy for security gate-ways based on swing door trending algorithm

Abstract

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.
