摘要
目前研究波长转换器对WDM网络性能影响的文献一般都是针对单光纤网络并且不考虑网络抗毁的要求。该文使用整数线性规划建模和动态系统仿真的方法,分别研究了静态业务和动态业务下,多光纤网状WDM网络在满足抗毁要求时,节点配置波长转换器对网络性能的影响,以此对使用波长转换器获得的好处给出较为全面的结论。
Currently, most papers that study the effect of wavelength translation on WDM network usually aim at single-fiber network and do not consider the requirement of network survivability. This paper studies network performance of multi-fiber WDM mesh networks while nodes install wavelength converter and satisfy the requirement against single-link failure under dynamic traffic demand and static traffic demand, respectively. Used methods include integer linear programming (ILP) and simulation. Benefits of wavelength translation to resilient multi-fiber WDM mesh networks will be more completely described.
