    摘要： A system for transferring a live application from a source to a target machines includes memory capture component that monitors and captures memory segments associated with one or more memories, one or more sets of these memory segments comprising one or more applications, the memory segments changing while the live application is in execution. A frequency ranking component organizes the memory segments in an order determined by memory segment change frequency. A link identification component identifies one or more connecting links to one or more sets of peer machines, each set of machines connecting said source machine to said target machine, the link identifier further determining the bandwidth associated with each connecting link. A routing component preferentially routes one or more of the memory segments over said connecting links based on said order.

    摘要： A method monitors machine activity of multiple virtual computing devices operating through at least one physical computing device by running a monitoring agent. The monitoring agent monitors performance of the multiple virtual computing devices. The method measures simple operating characteristics of only a base level virtual computing device. The method monitors complex operating characteristics using the monitoring agent by: measuring the complex operating characteristics for each of the multiple virtual computing devices (using each of the multiple virtual computing devices); recording the complex operating characteristics of each of the multiple virtual computing devices on a corresponding memory page of each of the multiple virtual computing devices; and sharing each the corresponding memory page with the base level virtual computing device through an interdomain communications channels to transfer the complex operating characteristics to the monitoring agent. The method identifies simple events and complex events for each of the multiple virtual computing devices by evaluating the simple operating characteristics and the complex operating characteristics and outputs the simple events and the complex events for each of the multiple virtual computing devices.

    摘要： One embodiment of the present method and apparatus for re-establishing anonymous data transfers between a first endpoint and a second endpoint in a network includes receiving, from a first node, the identity of a second node connected to the first node, where at least the first node is a neighbor node. A third node (a neighbor node) is then selected, and instructed to connect to the second node in order to establish a link for the path. In this manner, the first endpoint and the second endpoint remain unknown at least to each other (e.g., where “unknown” means that neither endpoint knows any identifying information, such as network address, about the other endpoint), and likely to all other nodes in the path as well. In another embodiment, a failure is detected at a neighbor node, where the neighbor node is part of an original path between the first endpoint and the second endpoint. The neighbor node's repair server is contacted for a repair node associated with the neighbor node, and a connection to the repair node is made such that the path is established in a manner that maintains anonymity of the first endpoint and the second endpoint relative to each other.
