With routing defined in a logical layer above the physical network, it is possible to have many overlapping topologies implemented on the same network fabric.
下面我们回到物理层来仔细看看访问器。
Next we switch back to the physical level and take a closer look at accessors.
如果需要新的物理层能力，比如新的资源模型，那么必要的访问器、transreptors等等就会构建起来。
If any new physical level capabilities are required, such as a new resource model, the necessary accessors, transreptors, etc. are constructed.
结果ProjectExplorer看起来是一样的，但是log4j.jar文件上一个小小的图标表明这个资源是工作空间以外的链接到一个物理层的资源。
The resulting Project Explorer looks the same, but a small icon on the log4j .jar file indicates that the resource is linked to a physical file outside the workspace.
NetKernel的逻辑模型集中于信息处理，而且通过一个微内核将逻辑模型与物理层对象和API干净地分离。

NuCrypt's proprietary "AlphaEta" quantum-noise randomized, physical-layer encryption technology represents a new paradigm in ultra-secure, high data-rate optical communications.
由于RPR是第二层基于MAC的技术，所以它能在多个物理层上工作，包括SONET。
Because RPR is a layer 2 MAC-based technology, it can operate over multiple physical layers, including SONET.
Transreptors通过对逻辑层隐藏了物理层的细节，来降低复杂性以此让开发者把精力集中在最重要的东西—信息。
Transreptors help reduce complexity by hiding physical level details from the logical level allowing developers to focus on what's important - information.
了解它位于应用程序层和物理层之间，应该可以帮助您理解它为什么很可能是所有层中最重要的一层。
Understanding that it sits between the application layer and the physical layer should help you understand why it is arguably the most important of all the layers.
在第一次设置系统时，对于磁盘的配置，可以从最底层(物理层)开始，然后是设备层、逻辑卷、文件系统、文件和应用程序。
When first setting up your systems, start from the bottom (the physical layer) as you configure your disk, the device layer, its logical volumes, file systems, and the files and application.
在本文的示例中，您更改了在物理层实现消息路由的假设和做法，并将其向上移动到了逻辑层中，并在那里由集群进行管理。
In this example, you changed the assumption and practice of implementing message routing at the physical layer and moved it up into a logical layer where it is managed by the cluster.
甚至物理卷本身也是逻辑层的一部分，因为物理层仅包含实际的磁盘、设备驱动程序和任何可能配置的阵列。
Even your physical volumes themselves are part of the logical layer, as the physical layer only encompasses the actual disks, device drivers, and any arrays that you might have already configured.
逻辑层可以跨物理层，并且可以将一个或多个、甚至所有的层分配到一个物理层。
