我们考虑多通道多跳光波网络的站配备了少量的发射机和接收机。通过将波长分配给每个站的接收器和发射器，可以独立于底层物理拓扑来定义网络的逻辑连通性。快速可调谐光发射器和接收器的出现使得动态更新网络连接以适应随时间变化的流量需求成为可能。在这种设计中，主要关注的是连接应该如何对流量模式的变化做出反应。该问题被制定为一个马尔可夫决策过程和最优配置策略的属性被确定。然后，这些属性被用来开发一种算法，用于获得决策类似于最优策略的决策的策略。还提出了一个程序来管理大量的站的系统的大状态空间。
We consider multichannel multihop lightwave networks with stations equipped with a small number of transmitters and receivers. By assigning wavelengths to the receivers and transmitters at each station, one can define the logical connectivity of the network independently of the underlying physical topology. The advent of fast tunable optical transmitters and receivers makes it feasible to dynamically update the network connectivity to accommodate traffic demands that vary over time. Of major concern in such design is how the connectivity should react to changes in traffic patterns. The problem is formulated as a Markovian Decision Process and the properties of the optimal configuration policy are identified. These properties are then used to develop an algorithm for obtaining policies that make decisions similar to the decisions of the optimal policy. A procedure is also proposed to manage the large state space for systems with a large number of stations.
