    Abstract: In some cases, a network monitoring system may determine an operating or health condition of a node or connection link in a network (e.g., a datacenter network) by preparing an encapsulated data packet according to a tunneling protocol. Depending on a result of routing the encapsulated data packet, the network monitoring system determines whether the node or connection link is functioning normally or is experiencing an issue such as overloading or malfunctioning.

    Abstract: A cooperative phase tracking system allows access points of a wireless network (e.g., a WiFi network) to use a clock or oscillator that may be different or independent from other access points of the same wireless network. As such, the cooperative phase tracking system eliminates a limitation of using a same clock (or oscillator) among the access points and at the same time may allow more access points to be installed for an associated wireless network to serve a larger area. Moreover, the cooperative phase tracking system may attribute intensive computations of relative phase drifts associated with the access points to a dedicated coordinator, thereby alleviating workload of the access points of the wireless network.

    Abstract translation: 协作相位跟踪系统允许无线网络（例如，WiFi网络）的接入点使用可以与同一无线网络的其他接入点不同或独立的时钟或振荡器。 因此，协同相位跟踪系统消除了在接入点之间使用相同时钟（或振荡器）的限制，并且同时可以允许针对相关联的无线网络安装更多的接入点来服务于更大的区域。 此外，协同相位跟踪系统可以将与接入点相关联的相对相位漂移的密集计算归因于专用协调器，从而减轻无线网络的接入点的工作量。

    Abstract: A network address mapping system is described. The network address mapping system can identify a set of Web pages, collects information from the Web pages indicating geographical locations (“geolocations”), and correlate the geolocations with the network addresses from which the identified Web pages are served. The collected information can be weighted based on various factors, such as its relative position in a Web page. The collected information can then be used to identify a geolocation. The network mapping system can deduce geolocations for portions of ranges of network addresses based on the score, and can infer geolocations for other portions based on the deduced geolocations. This mapping can then be stored in a database and provided as a geomapping service. The network address mapping system is able to map network addresses to geographical locations. Thereafter, when a user's client computing device accesses a Web server, the Web server can easily and accurately determine a geographical location by querying the database storing the mapping or a geomapping service.

    Abstract translation: 描述网络地址映射系统。 网络地址映射系统可以识别一组网页，从指定地理位置（“地理位置”）的网页收集信息，以及将地理位置与所识别的网页从其提供的网络地址相关联。 所收集的信息可以基于各种因素加权，例如其在网页中的相对位置。 然后可以使用收集的信息来识别地理位置。 网络映射系统可以基于分数推断出部分网络地址范围的地理位置，并且可以基于推导的地理位置来推断其他部分的地理位置。 然后，该映射可以存储在数据库中并作为地理服务提供。 网络地址映射系统能够将网络地址映射到地理位置。 此后，当用户的客户计算设备访问Web服务器时，Web服务器可以通过查询存储映射的数据库或地理位置服务来容易且准确地确定地理位置。

    Abstract: Described is a technology by which a gesture made with a source device (e.g., a cellular telephone), such as a throwing or pointing motion, is used to automatically set up a connection with another device to which the gesture is directed. Audio signals output during the gesture, e.g., such as at the start and end of the gesture, are detected by candidate (listening) devices. The device having the least time difference between detection of the start and end signals is the device that is generally best aligned with the throwing or pointing motion, and thus may be selected as the target device. Once selected, a connection such as a network connection may be set up between the source device and the target device for further communication, such as for application data exchange.

    Abstract: The techniques discussed herein reduce the power consumption of a Wi-Fi tethering device by switching the Wi-Fi functionality of the Wi-Fi tethering device from a normal operational mode to a sleep mode during idle intervals. The techniques implement a sleep protocol where a Wi-Fi tethering device and the Wi-Fi client device coordinate and establish a sleep schedule. Moreover, the techniques describe a sleep interval adaptation algorithm to establish sleep duration intervals based on data packet exchange patterns associated with different applications executing on the Wi-Fi client device and/or different operations being performed by the Wi-Fi client device.

    Abstract: A system, method or computer readable medium to provide efficient congestion notification is described herein. In various embodiments, a packet is received at an intermediate node of one or more data center networks. A current queue length at the intermediate node is determined. A threshold value for the current queue length is tuned by dynamically computing an upper bound and a lower bound based at least in part on the network. The packet is marked to indicate possible congestion in the one or more data center networks when the current queue length exceeds the threshold value. In some embodiments, the packet is marked when it is being de-queued. In a further embodiment, Flexible Initial Packet Size (FIPS) may be utilized to improve the efficiency of the tuning.
