在WDM全光网络中实现实时Multicast功能是计算机网络的应用要求,也是现代计算机网络的重要特征。该文提出了一种在WDM全光网络中实现实时Multicast的算法。该算法以辅助的波长图为基础,将寻径与波长分配统一进行,构造满足延迟约束的、具有较低成本的Multicast树,实现Multicast功能。
The realization of real-time Multicast function in WDM all-optical network is the application requirement of computer network and also an important feature of modern computer network. This paper proposes an algorithm to realize real-time Multicast in WDM all-optical network. Based on the auxiliary wavelength map, the algorithm performs uniform routing and wavelength allocation, constructs a lower-cost Multicast tree that satisfies the delay constraint and implements Multicast function.
