    摘要： The subject disclosure is directed towards configuring and controlling wireless flyways (e.g., communication links between server racks provisioned on demand in a data center) to operate efficiently and without interfering with one another. Control and flyway selection may be based upon steered antenna directionality, channel, location in the data center, transmit power, and measured and/or predicted (estimated) network traffic. Flyways also may be used to route indirect traffic to reduce traffic on a bottleneck (e.g., wired) link. A payload may be sent over a over a wireless flyway with acknowledgment via a wired backchannel so that wireless communication is in one direction. The lack of interference and communication in one direction facilitates flyway operation without a backoff function and/or without clear channel assessment.

    摘要翻译： 主题公开涉及配置和控制无线飞行路线（例如，在数据中心中按需提供的服务器机架之间的通信链路），以有效地操作并且彼此不干扰。 控制和飞行选择可以基于导向天线方向性，信道，数据中心中的位置，发射功率以及测量和/或预测（估计的）网络业务。 飞行路线还可用于路由间接流量以减少瓶颈（例如，有线）链路上的流量。 有效载荷可以通过无线飞行通过经由有线后向信道的确认发送，使得无线通信在一个方向上。 在一个方向上缺乏干扰和通信便于没有退避功能的飞行操作和/或没有明确的信道评估。

    摘要： A caching filter driver which is adapted for communicating with a universal serial bus (USB) mass storage device, the caching filter driver is adapted to: (a) receive a first reading request for a first size data from a USB mass storage driver; (b) determine if requested data which is requested in the first reading request is included in a prefetched read data cache; (c) issue a second reading request for a second size data to the USB mass storage device; and store the second size data in the prefetched read data cache, if the requested data is not included in the prefetched read data cache; and to (d) provide the requested data from the prefetched read data cache; wherein the second size is larger than the first size and the second size data includes the first size data; wherein the caching filter driver resides below the USB mass storage driver.
