Migrating a virtual machine that owns a resource such as a hardware device
A computing device has first and second virtual machines (VMs) and a resource assigned to the first VM. Each access request for the resource is forwarded thereto until the first VM is to be saved or migrated. Thereafter, each access request is forwarded to a holding queue. When the resource has acted upon all access requests forwarded thereto, the resource is reassigned to the second VM, and each access request at the holding queue is forwarded to the second VM and then the resource. Thus, all access requests for the resource are acted upon by the resource even after the resource is removed from the first VM and assigned to the second VM, and the save or migrate of the first VM can thereafter be completed. |

Method and apparatus for appliance host supported network-based application delivery
A method and apparatus for appliance host supported network-based application delivery is described. In one embodiment, a local client device requests access to a network-based application for use with data stored locally by the client. In one embodiment, an appliance host retrieves the network-based application from a remote server based upon the client request and negotiated access terms. In one embodiment, the appliance host operates much like a cache in that rather than automatically retrieving the client-requested network-based application from a remote server, the appliance host first determines if a local copy of the application is stored on the appliance host. If the network-based application is stored on the appliance host, whether pre-installed by the vendor or remaining from a previous client request, then the appliance host executes the locally stored version of the application rather than retrieving a copy from the remote server. Since the network-based application is executed locally (with respect to the client) rather than at the remote server location, any communication interruptions that may occur outside the local network will not affect execution of the network-based application. |

Using cross-site relationships to generate recommendations
A relationship server tracks end-user interactions across multiple web sites and generates recommendations. The web sites observe relationships established by end-user interactions. If end-users provide the same personally identifiable information to multiple web sites, the sites generate the same unique identifier for those end-users. The web sites send messages to the relationship server that reference the end-users using the identifiers and describe the relationships observed for the end-users. The relationship server receives messages from multiple web sites and canonicalizes them to produce an efficient representation of the relationships. Upon receiving a message requesting a recommendation based on an item, the relationship server performs collaborative filtering using the relationship data to identify a list of items to recommend. The relationship server sends the recommendations to the requesting entity and the recommendations are presented to the end-user. |

Using stochastic models to diagnose and predict complex system problems
A plurality of stochastic models is built that predict the probabilities of state transitions for components in a complex system. The models are trained using output observations from the system at runtime. The overall state and health of the system can be determined at runtime by analyzing the distribution of current component states among the possible states. Subsequent to a low level component failure, the state transition probability stochastic model for the failed component can be analyzed by uncovering the previous states at N time intervals prior to the failure. The resulting state transition path for the component can be analyzed for the causes of the failure. Additionally, component failures resulting from the failure, or worsening state transition, in other components can be diagnosed by uncovering the previous states at the N times prior to the failure for multiple components in the system and then analyzing the state transition paths for correlations to the failed component. Additionally, transitions to worsening states can be predicted using an action matrix. The action matrix is created beforehand using state information and transition probabilities derived from a component's stochastic model. The action matrix is populated probabilities of state transitions at a current state for given actions. At runtime, when an action is requested of a component, the probability of the component transitioning to a worsening state by performing the action can be assessed from the action matrix by using the current state of the component (available from the stochastic model). |

In-network per packet cashes
Methods, systems, and media are provided for the improved efficiency in bandwidth usage for transmitting repeated packets in a manner that is transparent to users. Fast, in-network per-packet caches (INPPC) at each node of a transmission retain packets for a configurable period of time or a number of packets.

Uplink inter-carrier interference cancellation of OFDMA systems
Inter-carrier interference (ICI) cancellation in an OFDMA receiving signals from two transmitters is performed by identifying the transmitted sub-carriers that cause the largest ICI to sub-carriers received from other transmitters, and removing the ICI contribution from these sub-carriers. This may be accomplished by calculating the ICI terms only based on the interfering sub-carrier and the frequency offset. Alternatively, the transmissions causing the ICI are demodulated, the ICI on other signals is then determined and subtracted, and other signals are then demodulated. Which transmissions cause the largest ICI on others depends on the relative strength of the corresponding sub-carriers and how much orthogonality is lost. The latter might be due to frequency error, Doppler spread, or a combination of both. |
