Abstract: A precaching system identifies an object, such as a media file, that a user accesses and then analyzes a social graph of the user to identify social graph contacts that may be interested in the object. Based on the content of the object—and the interests and connections of contacts in the social graph—the precaching system determines whether a particular contact in the user's social graph is likely also to access the object. For example, the precaching system may determine a hit score corresponding to the object and a likelihood that the particular contact in the social graph will access the object. If the precaching system determines that the likelihood that the particular contact will access the object meets or exceeds a threshold probability level for precaching the object, the precaching system precaches the object near the contact in anticipation that the contact will access the object.

Abstract: Techniques are presented herein to provide human mobility pattern based modeling and tracking of a group of network enabled user devices associated with the same person. An association is made, at a tracking device, between a plurality of user devices and a user. Location information for each of the plurality of user devices is derived through network activity of the plurality of user devices. Locations for the plurality of user devices are derived from the location information. One or more predetermined user mobility pattern rules are applied to the plurality of user devices. User anomalies are detected when the tracked locations indicate that one or more of the plurality of user devices has violated one or more the predetermined user mobility rules.

Abstract: An edge server communicates with a client in a local network. The client displays a remote desktop image representative of a virtual desk image generated by a virtual desktop server (VDS). The edge server receives from the VDS a desktop image to be displayed on the remote desktop. The desktop image includes an incomplete window in which graphic media, such as video, is to be displayed. The edge server determines communication link conditions in the local network and a corresponding transmit data rate at which to transmit data to the client device and a suitable encoding rate at which the graphic media is encoded. The edge server downloads the graphic media from the content server, merges the downloaded graphic media into the incomplete area to produce a completed desktop image, and transmits the completed desktop image at the determined transmit data rate for display on the remote desktop.

Abstract translation: 边缘服务器与本地网络中的客户端进行通信。 客户端显示代表虚拟桌面服务器（VDS）生成的虚拟桌面映像的远程桌面映像。 边缘服务器从VDS接收桌面图像以在远程桌面上显示。 桌面图像包括不完整的窗口，其中将显示诸如视频的图形媒体。 边缘服务器确定本地网络中的通信链路条件以及将数据发送到客户端设备的相应发送数据速率以及对图形媒体进行编码的合适的编码速率。 边缘服务器从内容服务器下载图形媒体，将下载的图形媒体合并到不完整的区域，以产生完整的桌面图像，并以确定的传输数据速率传输完整的桌面映像，以便在远程桌面上显示。
