Physical Layer PHY

This algorithm combined sub-carrier allocation in the physical(PHY) layer with traffic scheduling at the data link layer (DLL) by employing the channel state information.

利用物理层的信道状态信息，该算法将物理层（PHY）的子载波分配同数据链路层（DLL）的数据包业务调度结合起来。

The PHY (physical layer) provides the electrical and mechanical interface between the device and the cable and ensures that all devices have fair access to the bus.

物理层为设备提供了一个物理和电气接口，保证总线上的所有设备都能公平地访问总线。

The company's plans beyond these modules are unknown, but Luxtera could continue to reserve the technology for its own silicon for networking physical-layer (PHY) components.

该公司在这些模块之外还有什么计划，尚不得而知，但Luxtera可以继续将该技术留给自己的硅基网络物理层（PHY）元件。
