第四章中提出一种详尽的基于GMPLS的方法来配置全光多域DWDM网络中的光路径。
The fourth chapter describes a detailed hierarchical routing GMPLS-based framework for provisioning all-optical DWDM optical networks.
但是光并非只走一条路径,而是可以从两个或四个不同路径中的一个绕过物体,这样科学家可以获得两倍或四倍的信息量。
But instead of taking a single path, light can bend around the object in one of two, or four different routes, thus doubling or quadrupling the amount of information scientists receive.
例如,当恒星发出的光经过一个星系附近,其路径会弯曲,改变恒星出现在天空中的位置——这就是所谓的引力透镜效应。
When light from a star passes near a galaxy, for example, its path bends, changing where the star appears in the sky-the so-called gravitational lensing effect.
