为了提高网络带宽利用率,实现网络负载和传输效率的平衡,提出了一种基于网络流量自回归技术的网络数据去重算法ANTREA.该算法将数据传输分割成多个传输单元,在每个传输单元中分成去重传输和直接传输2部分,前一部分实现去除冗余数据后传输,后一部分数据则利用空闲带宽实现传输.通过为每个传输单元的网络状况建模,预测下一个传输单元的网络可用带宽及查重处理时间,并据此调整直接传输的数据量,以求充分利用空闲带宽,提高网络带宽利用率.实验结果表明,ANTREA算法可以根据网络状况自动调整传输策略,能够充分利用网络带宽以实现更高的数据传输效率,比EndRE算法有更好的网络适应性,在10 MB/s的网络环境下,传输吞吐量几乎为EndRE的7倍.
In order to improve the utilization ratio of network bandwidth and achieve the balance between network load and transmission efficiency, an ANTREA network data de-duplication algorithm based on network traffic autoregression is proposed. The algorithm divides the data transmission into multiple transmission units, The unit is divided into two parts: Deduplication and Direct Transmission, the former part to achieve the removal of redundant data transmission, the latter part of the data is to use idle bandwidth to achieve transmission. By modeling the network conditions for each transmission unit, predict the next transmission unit Network available bandwidth and checking the processing time and adjust the amount of data to be transmitted directly in order to make full use of free bandwidth and improve network bandwidth utilization.The experimental results show that ANTREA algorithm can automatically adjust the transmission strategy according to network conditions and can take full advantage of Network bandwidth to achieve higher data transmission efficiency, better network adaptability than EndRE algorithm, in 10 MB / s network environment, the transmission throughput is almost 7 times EndRE.
