为了提高光纤网络的数据传输的可靠性,降低丢包率,在分析当前光纤网络信道接入机制缺陷的基础上,提出了一种基于线性编码的光纤网络信道接入机制。首先对光纤网络信道接入机制进行分析,然后对传统编码方式进行改进,采用双解码方式来对数据包进行解码,提高数据包解码成功率,最后采用OPEN工具对信道接入机制进行仿真模拟实验。实验结果表明,线性编码的光纤网络信道接入机制提高了数据包发送的成功率,降低了数据传输的时延,获得比传统光纤网络信道接入机制更优的通信结果,应用范围更加广泛。
In order to improve the reliability of data transmission in optical fiber networks and reduce the packet loss rate, a novel optical fiber network channel access mechanism based on linear coding is proposed based on the analysis of the defects in the current optical fiber network access mechanism. Firstly, the channel access mechanism of optical fiber network is analyzed, and then the traditional encoding method is improved. The double decoding method is adopted to decode the data packet to improve the success rate of data packet decoding. Finally, the OPEN tool is used to simulate the channel access mechanism . The experimental results show that the linear coding optical fiber network channel access mechanism improves the success rate of data packet transmission, reduces the data transmission delay and obtains better communication results than the traditional optical fiber network channel access mechanism, and the application scope is more extensive.
