摘要
在全光网络数据信息始终以光波信号的形式存在,要求节点具有足够的传输容量,为此提出了全光信息网络中的节点传输容量优化方法。首先构建全光网络节点传输容量优化模型,均衡节点负载;修正节点容量函数,搜寻全光网络中最优的归一化信号幅值,将网络噪声干扰控制在最小化水平,采用此时的发送功率优化链路负载和节点功能,提高全光信息网络节点传输容量和网络性能。仿真实验表明提出的优化方法,能够提高节点数据传输的吞吐量、扩大局部网络覆盖率、降低外界环境的干扰、系统误差也能够得到较好的控制。
The optical switching frequency is low in all optical information network, which can effectively improve the utilization of network resources. In addition, all optical network has strong security and anti interference capacity. In all optical networks, the data information always exists in the form of the optical wave signal, which requires the node has enough transmission capacity. First constructing of all-optical network node transmission capacity optimization model to balance node loading. Building node capacity correction function and normalizing signal amplitude oplireal search in all-optical networks to control the network noise Building in minimizing level. Using the current transmission power to optimize link load and node function, and improve the optical information network transmission capacity and network performance. Simulation results show that the proposed algorithm can improve the throughput of node data transmission, expand the coverage rate of local network, reduce the interference of the external environment, and the system error can be controlled well.
