波分复用(WDM)光网络是航空机载网络发展的方向,采用波长路由和电交换相结合是解决目前机载WDM光网络互连的主要途径。其中的一个关键问题是如何对航空机载网络节点进行子网划分,将相互之间通信流量大的节点划入同一个子网,采用波长路由通信;将相互之间通信流量小的节点之间采用电交换互连。采用多维空间聚类的算法思想,将网络节点通信流量问题转换为空间聚类问题,进行节点流量位置预处理和节点流量位置聚类两个过程,解决了航空机载WDM子网划分问题,并通过实例验证了方法的可行性。
Wavelength Division Multiplexing (WDM) optical network is the development direction of the airborne network. The combination of wavelength routing and electric exchange is the main way to solve the current interconnection of airborne WDM optical networks. One of the key issues is how to subnet the nodes of the airborne network, divide the nodes with large communication traffic into the same subnet, and use the wavelength routing to communicate; and use the nodes with small communication traffic between each other Electrical exchange interconnection. The algorithm of multi-dimensional spatial clustering is used to convert the communication traffic of network nodes into spatial clustering problem, and the process of node traffic location preprocessing and node traffic location clustering are two processes to solve the problem of airborne WDM subnetting. The feasibility of the method is verified by an example.
