Design of Transmission Delay Control System for Big Data Communication Based on PCIE Bus
In big data transmission,when network traffic is too large or 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 communica-tion network,a big data communication transmission delay control system based on peripheral component interconnect express(PCIE)bus is designed.Design the big data transceiver,communication conversion module,and communication interrupt controller under the PCIE bus core structure,build the 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,the feedback information related to the communication transmission delay state is obtained,and based on this,the specific control scheme is determined to complete the design of the big data communication transmis-sion delay control system based on the PCIE bus.Experimental results show that the PCIE bus control system can control the big data communication delay within the range of 0～0.20 ms,without causing a decrease in the instantaneous response rate of data informa-tion due to excessive delay,and the packet loss rate of data transmission is below 10％,which meets the requirements of practical ap-plication.
