摘要
介绍无源光网络接入网技术及网络编码的基本理论,将网络编码应用到无源光网络体系结构中,重点阐述系统中数据交换过程,理论分析证明在不改变硬件设备的条件下,可以提高无源光网络系统的下行吞吐量,提高网络的带宽利用率。最后,结合缓冲策略给出了可以进一步实现的软件框架模型和基本算法。
After the introduction of the rationales of accessing network technology and network coding of passive optical networks（PON） in the paper,we apply the network coding to architecture of PON,the emphasis is put on expatiating on the data exchange process in the system.Theoretical analysis proves that the downlink throughput of PON system and the bandwidth usage of the network can be increased without altering the hardware device.In end of the paper,a software framework model of PON system and its basic algorithm available to be further realised are proposed in conjunction with the buffering strategy.
