摘要: 目前研究波長轉(zhuǎn)換器對WDM網(wǎng)絡(luò)性能影響的文獻(xiàn)一般都是針對單光纖網(wǎng)絡(luò)并且不考慮網(wǎng)絡(luò)抗毀的要求。該文使用整數(shù)線性規(guī)劃建模和動態(tài)系統(tǒng)仿真的方法,分別研究了靜態(tài)業(yè)務(wù)和動態(tài)業(yè)務(wù)下,多光纖網(wǎng)狀WDM網(wǎng)絡(luò)在滿足抗毀要求時(shí),節(jié)點(diǎn)配置波長轉(zhuǎn)換器對網(wǎng)絡(luò)性能的影響,以此對使用波長轉(zhuǎn)換器獲得的好處給出較為全面的結(jié)論。

Abstract: 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. -
