并行冗余网络中高效信息采集策略设计

基于并行冗余网络结构提出一种带宽占用率小的网络状态参数采集策略。采用线性预测的方法,自适应的调整信息采集的时间间隔,通过获取少量网络状态数据样本,进而能够获得整个网络样本空间的主要性能状态指标的精确估计。最后通过OMNET＋＋网络仿真软件对高效信息采集策略进行了仿真验证,仿真结果表明：提出的高效信息采集策略相比传统的信息采集方法的带宽占用率减小了约69%。

Design of an efficient information collection method in parallel redundancy network

Based on the parallel redundancy network(PRP),this paper introduces a network status parameter acquisition strategy with low bandwidth consumption rate.Using linear prediction method to adjust the sampling time interval adaptively.Then,By means of collecting a small amount of network status data sample,we can be able to obtain accurate estimation of the main properties of the sample space of the entire network.Finally,the OMNET++ network simulation software is used for simulation and verification,results show that:compared to traditional information collection methods,bandwidth occupancy rate of the efficient information collection policies is reduced by about 69%.
