摘要： In an automatically switched optical network operating according to a wavelength plan, the wavelengths are assigned to an optical path based on availability, performance and SRS wavelength coupling reduction. First, the wavelengths are grouped in static bins based on their reach versus cost performance, and each bin assumes a ΔQ of a middle wavelength. Then, the bins are moved into subsets of dynamic bins, constructed using bin constraints that account for the particulars of the respective optical path. The path is characterized taking into account the wavelength currently accessing at the end nodes, and the wavelength tandeming through the end nodes. Wavelength selection starts with the bins that satisfy the maximum number of constraints, and the wavelengths are checked sequentially against wavelength constraints; relaxed constraints are also applied when it is not possible to exactly satisfy one or more constraints.

摘要： Routing and bandwidth assignment of new paths of different bandwidths, occupying different numbers of adjacent frequency slots in a wavelength switched optical network, involves selecting a route, and assigning a set of adjacent frequency slots. The assignment can place wider bandwidth ones of the new paths at an opposite end of a spectrum of the available frequency slots, to an end where narrower bandwidth ones are placed. A size of sets of available adjacent slots remaining after the assignment is likely to be increased, compared to a conventional first fit assignment. A wider subsequent new path can sometimes be accommodated along all or some of the route and thus the blocking probability can be lowered. The selecting of which of the possible routes to use can be made dependent on which has more sets of available adjacent frequency slots, or which has a wider gap between occupied slots.
摘要翻译：在波长交换光网络中占用不同数量的相邻频率槽的不同带宽的新路径的路由和带宽分配涉及选择路由和分配一组相邻频率时隙。该分配可以将更宽的带宽的新路径放置在可用频率隙的频谱的另一端，到达放置较窄带宽的端点。与传统的第一拟合分配相比，分配之后剩余的可用相邻狭缝的集合的大小可能增加。有时可以沿着所有或某些路线容纳更宽的后续新路径，从而可以降低阻塞概率。可以选择要使用哪些可能的路由取决于哪些具有更多的可用相邻频率槽的集合，或者在占用时隙之间具有更宽的间隙。
