长距离光纤接入网络优化通信研究与仿真

Research and Simulation of Optimization Communication of Long Distance Optical Fiber Access Network

在光纤接入网络通信优化的研究中,光纤接入网络交换机和终端设备不能适应长距离通信需求,一旦距离过长,光信号强度会大规模衰减,直至网络数据无法传输。传统的解决办法只能依靠增加中继放大设备,不断对衰减信号进行补偿,实现长距离通信,但补偿过程仅仅通过距离判断,能耗高,补偿过程不细致,效果不佳。提出一种光纤接入网络优化编码的方法优化通信过程,利用优化编码构建多个虚拟专网机制,用虚拟专网替代硬件设备,使网络数据实现在任何一个虚拟专网中都完整准确地传递,实现数据在光接入网络中的长距离传输。在仿真中引入了数据吞吐量增益做为测试的标准,来检验数据在每一个虚拟专网和多个虚拟专网中传输的完整性,结果表明,利用优化编码方法构建虚拟网络,数据在每个专网和多个虚拟专网中都能完整的传输。

In the research of communication optimization of optical fiber access network, optical fiber access net- work switch and terminal equipment can＇t adapt to the requirements of long distance communication, once the distance is too long, large -scale attenuation in light signal strength will occur, resulting in that the network data can＇t be trans- ferred. This paper presented an optical fiber access network optimization encoding method to optimize the communica- tion process. The optimization encoding construct multiple virtual private networks mechanism and the virtual private network were used to replace the hardware equipment, which can make integrated and accurate transformation of net- work data in any virtual private network, and realize long distance data transmission in the optical fiber access net- work. Data throughput gain was introduced as test standard to the simulation experiment, to test the integrity of data transmission in every virtual private network and multiple virtual private networks. The results show that using optimi- zation encoding method to build a virtual network, the data in every of the private network and multiple virtual private networks can be transmited completely.
