摘要:

摘要:对变电站中“共网共口”的实现方法进行研究,首先研究通过VLAN 与分时传输报文实现“共网共口”的方法,然后基于光纤的波分复用特性,研究将不同业务映射到不同波长的波长映射方法,并在此基础上提出了基于全光交换的“共网共口”传输方法,此方法可以通过边缘预处理设备和光交换设备构建智能变电站站内一体化高速通信网络。

Abstract:

To realize shared-port and shared-network in substation,a method based on VLAN and the time division multiplexing technology were studied,and the wavelength mapping method based on WDM technology by mapping different services to different wavelengths was put forward.Finally,a method based on optical switch was put forward which realized the “shared-port and shared-network”by edge pre-processing equipment and optical switching equipment.

Key words: shared-port and shared-network, virtual local area network, time division multiplexing, wavelength division multiplexing, wavelength mapping, all-optical switch
