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 the optical fiber network and reduce the packet loss rate,this paper puts forward a optical fiber network channel access mechanism by using linear code based on analysis the defects of current optical fiber network channel access mechanism. Firstly,the optical fiber network channel access mechanism is analysed,and secondly the traditional coding method is improved by using dual decoding of packet decoding to improve packet decoding success rate,lastly,the simulation experiment is used to test the performance of the channel access mechanism by using OPEN tools. The experimental results show that the proposed fiber network channel access mechanism improves the success rate of packet transmission,and reduce the data transmission delay,the communication results are better than the traditional optical fiber network channel access mechanism and application range is more wide.
