摘要:

在大数据传输中,当网络流量过大或网络拓扑复杂时,可能会出现网络拥塞的情况,导致通信传输时延的增加,为了优化通信网络的数据传输效率,设计基于PCIE总线的大数据通信传输时延控制系统。在PCIE总线核结构下设计大数据收发器、通信转换模块与通信中断控制器,搭建时延控制终端,联合大数据通信寄存器与时延状态估计器,实现传输时延控制硬件系统的设计。在通信数据相空间内,计算传输时延量的具体数值水平,完成对大数据通信传输时延的预测。根据大数据通信序列定义条件,得到与通信传输时延状态相关的反馈信息,并以此为基础,确定具体的控制方案,完成基于PCIE总线的大数据通信传输时延控制系统设计。实验结果表明,PCIE总线控制系统的应用可将大数据通信时延控制在0-0.20ms范围之内,不会因时延过大造成数据信息瞬时响应速率下降的问题,且数据传输丢包率低于%,符合实际应用需求。

Abstract:

In big data transmission, when the network traffic is too large or the network topology is complex, network congestion may occur, leading to an increase in communication transmission delay. In order to optimize the data transmission efficiency of the communication network, a big data communication transmission delay control system based on PCIE bus is designed. Design a big data transceiver, communication conversion module, and communication interrupt controller under the PCIE bus core structure, build a delay control terminal, and combine the big data communication register and delay state estimator to achieve the design of the transmission delay control hardware system. Calculate the specific numerical level of transmission delay in the communication data phase space, and complete the prediction of big data communication transmission delay. Based on the defined conditions of the big data communication sequence, feedback information related to the communication transmission delay state is obtained, and based on this, specific control schemes are determined to complete the design of the big data communication transmission delay control system based on the PCIE bus. The experimental results show that the application of the PCIE bus control system can control the delay of big data communication within the range of 0-0.20ms, without causing a decrease in the instantaneous response rate of data information due to excessive delay, and the packet loss rate of data transmission is less than%, which meets the practical application requirements.
