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。
In all-optical network, the data information always exists in the form of light wave signal, which requires the node to have sufficient transmission capacity. Therefore, the optimization method of node transmission capacity in all-optical information network is proposed. First, the optimization model of transmission capacity of all-optical network nodes is constructed to balance the load of nodes. The capacity function of nodes is modified to search the optimal normalized signal amplitude of all-optical networks. The network noise interference is minimized. Power optimizes the link load and node functions to improve the transmission capacity and network performance of all-optical information network nodes. The simulation results show that the proposed optimization method can improve the throughput of node data transmission, expand the coverage of local network and reduce the interference of external environment, and the system error can be well controlled.
