    摘要： Hosts or end-systems residing at the edges of a network gather data about the traffic they transmit into and receive from the network. The network's routing protocol (typically a link-state protocol such as OSPF) is monitored and routing data or packets are used to recover the network's current status and topology. This data can be collected, fused, and maintained and a platform, preferably distributed, can be provided to query the data, thus enabling a variety of network management applications.

    摘要： A data transfer system is described herein that allows data to be sent directly between two computing devices at the request of a third party client computer. The system allows a third party to initiate data transfers between computers in a network file system. This results in a significant speed increase because little to no data travels over the third party's potentially slower connection. The data transfer system provides a mechanism to determine if the direct transfer would be more efficient than two separate read and write operations, based on measurements of bandwidth and latency between each computing device. The data transfer system provides support for the source server to compress the data and the destination server to decompress the data at the direction of a third party client to further save network bandwidth.

    摘要翻译： 本文描述了允许在第三方客户端计算机的请求下在两个计算设备之间直接发送数据的数据传送系统。 系统允许第三方在网络文件系统中的计算机之间启动数据传输。 这导致显着的速度增加，因为几乎没有数据传播通过第三方的潜在较慢的连接。 基于每个计算设备之间的带宽和延迟的测量，数据传输系统提供了一种机制，以确定直接传输是否比两个单独的读取和写入操作更有效。 数据传输系统提供对源服务器的压缩数据和目的服务器的支持，以在第三方客户端的方向解压缩数据，以进一步节省网络带宽。

    摘要： A secure location system is described herein that leverages location-based services and hardware to make access decisions. Many mobile computers have location devices, such as GPS. They also have a trusted platform module (TPM) or other security device. Currently GPS location data is made directly accessible to untrusted application code using a simple protocol. The secure location system provides a secure mechanism whereby the GPS location of a computer at a specific time can be certified by the operating system kernel and TPM. The secure location system logs user activity with a label indicating the geographic location of the computing device at the time of the activity. The secure location system can provide a difficult to forge, time-stamped location through a combination of kernel-mode GPS access and TPM security hardware. Thus, the secure location system incorporates secure location information into authorization and other operating system decisions.

    摘要： A personal datacenter system is described herein that provides a framework for leveraging multiple heterogeneous computers in a dynamically changing environment together as an ad-hoc cluster for performing parallel processing of various tasks. A home environment is much more heterogeneous and dynamic than a typical datacenter, and typical datacenter scheduling strategies do not work well for these types of small clusters. Machines in a home are likely to be powered on and off, be removed and taken elsewhere, and be connected by an ad-hoc network topology with a mix of wired and wireless technologies. The personal data center system provides components to overcome these differences. The system identifies a dynamically available set of machines, characterizes their performance, discovers the network topology, and monitors the available communications bandwidth between machines. This information is then used to compute an efficient execution plan for data-parallel and/or High Performance Computing (HPC)-style applications.

    摘要： Activity models are maintained on a plurality of computers on a network. When a user or a particular activity model at a computer discovers an error, it may query its own activity model to determine a possible source of the error. If it is determined to not be the likely source of the error, the activity model queries the activity models of those computers on the network that it depends on. These activity models may then query the activity models of the computers that their particular host computer depends on and so forth. Ultimately the results of these activity model queries may be used to diagnose the likely source of the error and may be presented to the requesting user as a report.

    摘要： A performance monitoring system is described herein that works with a hypervisor to reserve resources outside of a virtual machine to monitor performance of an application running within the virtual machine. The application receives the guaranteed amount of resources specified by the virtual machine's specifications, and the monitoring consumes resources not associated with the virtual machine. The application running in the virtual machine is already isolated by the hypervisor from the physical machine, and thus additional burdens on the physical machine that allow the hypervisor to continue meeting guarantees to the virtual machine will not impact application performance. The performance monitoring system provides instrumentation of deployed applications that information technology (IT) personnel can dynamically turn on and off without affecting the performance of the deployed application. The performance monitoring system provides a robust framework for monitoring production applications without affecting the performance of those applications during execution.
