摘要
为了提高光纤网络的双向化通信容量,需要对网络通信容量优化方法进行研究。采用当前优化方法存在冗余数据消除效果差、负载均衡能力差和带宽利用率低的问题,提出一种光纤网络双向化通信容量优化方法,根据光纤网络中冗余数据采集速度和位置距离得到冗余数据相似度,基于相似度采用均值漂移传递函数得到冗余数据的活跃度,根据活跃度消除光纤网络双向化通信中的冗余数据,通过流量请求的拓扑链路和带宽需求的剩余容量等权重因子调整数据传输路径之间的流量分配比例,完成光纤网络双向化通信容量的优化。实验结果表明,本文方法的冗余数据消除效果好、负载均衡能力强、带宽利用率高。
In order to improve the bidirectional communication capacity of the optical network,it is necessary to study the network communication capacity optimization method. The current optimization method has the problems of poor redundancy data elimination,poor load balancing ability and low bandwidth utilization. A bidirectional communication capacity optimization method for fiber network is proposed. Redundant data similarity is obtained according to the redundant data acquisition speed and position distance in the fiber network. Based on the similarity,using the mean shift transfer function to obtain the activity of the redundant data. And eliminate the redundant data in the bidirectional communication of the optical network according to the activity. The traffic distribution proportion of data transmission is modulated through the weighting factors such as topology link of traffic request and remaining capacity of bandwidth to optimize the bidirectional communication capacity of the fiber network. The experimental results show that the proposed method has good redundancy data elimination,strong load balancing ability and high bandwidth utilization.
