Design of Survivable Routing with and without Wavelength-continuity Constraints in WDM Networks

The problem of routing logical links (lightpaths) on a physical topology of WDM networks in a way that the logical topology remains connected in the event of single physical link failure is called survivable routing. This paper addresses the survivable routing problem with and without wavelength-continuity constraints by proposing a new Integer Linear Programming (ILP) algorithm, which is based on a simplified necessary and sufficient condition. Numerical results are given and discussed to show that survivable routing solutions of most logical topologies can be found by the algorithm of the authors. Furthermore, comparing with other similar methods, the above algorithm can find out a survivable solution in much shorter time, and it works especially well with sparse-connected logical topologies. The impact of wavelength-continuity constraints and the other factors that influence the probability to find out a survivable solution are also discussed in the paper.

包含光学共振腔的干涉光学装置

光学通信系统在通信网络中随处可见。随着通信量的增加,数据传输速率也在增加,而可用的带宽就成了一种稀缺的资源。为了更有效地利用这一资源,人们在光学通信系统中普遍采用了波分多路传输技术。然而,波分多路传输系统需要准确的波段选择、稳定的可调谐激光器或滤波器以及良好的光谱纯度。这些不仅会增加其成本,而且还会增加其复杂性。
