摘要
电力城域网业务承载方式差别很大,网络交换节点不仅需要支持量子信号、同步信号和经典信号的交换,还需要具备多粒度的信号交换功能来支持不同服务等级电力业务的加密传输.采用基于光纤级交换层、波带级交换层和波长级交换层的多粒度量子交换节点结构,提高交换节点的灵活性并降低交叉连接矩阵的规模.同时,将波长选择开关引入多粒度量子交换节点,通过可编程的灵活波长选择保证了同用户量子信号与同步信号的同路径交换.仿真结果表明该量子交换节点结构在电力城域网中应用的可行性.
There are great differences in service carrying modes of power MAN. Network switching nodes not only need to support the exchange of quantum signals, synchronous signals and classical signals, but also need to have multi-granularity signal switching functions to support the encrypted transmission of power services of different service levels. A multi-granularity quantum switching node structure based on optical fiber level switching layer, waveband level switching layer and wavelength level switching layer is adopted to improve the flexibility of the switching node and reduce the size of the cross-connection matrix. At the same time, the wavelength selection switch is introduced into the multi-granularity quantum switching node, and the programmable and flexible wavelength selection ensures the same path switching with the user's quantum signal and synchronous signal. The simulation results show that the quantum switching node structure is feasible in the application of power metropolitan area network.
