Disclosed are techniques for using known update technologies to automatically identify the updates installed on a physical machine prior to facsimile creation, to locate the update packages from an update server, and to download them to the machine performing the facsimile creation. The use of update technologies enables precise identification of the updates that affect the defined set of files requiring replacement, and thus minimizes the number of updates that need to be downloaded. In addition, the desired set of replacement files are extracted and cached to allow for their reuse during subsequent facsimile creations using either the same or different physical or virtual machine as the source. Downloading the minimal set of updates and caching them for reuse eliminates the redundant downloads of updates and results in a shorter time for facsimile creation.

A computer-implemented system configured to describe the relationship between a first Namespace and a second Namespace is provided. The system includes a containment relationship identifying a direct relationship between a first object of the first Namespace and a second object of the first Namespace. Moreover, the system includes a junction relationship linking the second object of the first Namespace to a first object of the second Namespace. In one embodiment, the system is configured to facilitate the recovery of information based on the descriptions of the Namespaces that is maintained.

Described herein is a technology for the presentation of digital video. One implementation, described herein, smoothly presents variable-speed scanning of a compressed digital video stream—for example, a MPEG video stream. One implementation, described herein, smooth scanning (e.g., fast-forward and fast-rewind) video is produced by selectively displaying certain types of frames of a Group-of-Pictures (GOP). The scope of the present invention is pointed out in the appending claims.
摘要:
Deployment and servicing tasks associated with multi-tier, distributed applications, application environments and data centers are automated so that a person does not have to manually perform these tasks. All of the information describing and defining the distributed service is modeled and stored in a re-useable service template that can be used to drive an automated system to programmatically deploy and manage the service over time. Deployment and servicing of a distributed application can be automated using re-useable models that capture hardware and workload definitions. The re-useable models in the form of service templates enable delta-based servicing of the application. The service can be deployed to one or more physical machines, one or more virtual machines or to a combination thereof. A default deployment plan can be customized with instance-specific customizations of service parameters.

A virtual machine may be discovered through a directory service or via an agent that is installed on the host operating system that is running the virtual machine. If the agent is installed on the virtual machine, the agent monitors changes to a set of protected volumes on the virtual machine. If the agent is installed on the host, the agent monitors changes to the protected volumes, which may contain one or more virtual servers on the host. Periodically, these changes from the host or the virtual server are sent to a data protection server. The data protection server updates its replicas of protected volumes with the sent changes. Versions of files on a data protection server corresponding to a volume of a virtual server may be restored to the virtual machine, to another machine, or may be viewed from the data protection server.

A method and system for backing up and restoring data of virtual machines. A virtual machine may be discovered through a directory service or via an agent that is installed on the host operating system that is running the virtual machine. If the agent is installed on the virtual machine, the agent monitors changes to a set of protected volumes on the virtual machine. If the agent is installed on the host, the agent monitors changes to the protected volumes, which may contain one or more virtual servers on the host. Periodically, these changes from the host or the virtual server are sent to a data protection server. The data protection server updates its replicas of protected volumes with the sent changes. Versions of files on a data protection server corresponding to a volume of a virtual server may be restored to the virtual machine, to another machine, or may be viewed from the data protection server.
摘要:
Model-based provisioning of test environments includes accessing a model of an application to be installed in a test environment of a system and further accessing a model of the system and a model of the test environment. An installation specification for the application is also generated, the installation specification being derived at least in part from the model of the application, the model of the system, and the model of the test environment.
摘要:
A legacy computer system receives a hard drive or other hardware failure. Rather than attempting to rebuild the computer system or recover selected data, which may require locating discontinued hardware or even software, a virtual machine image is created from a previously prepared backup image of the hard drive. The retrieved backup image is modified to create a virtual image that is bootable on a virtual machine. Thus, the original computer environment stored on the legacy system is now virtualized removing the need to repair or replace the failed hardware.
摘要:
An interactive entertainment and information system using a television set-top box, wherein pages of information are periodically provided to the set-top box for user interaction therewith. The pages include associated meta-data defining active locations on each page. When a page is displayed, the user interacts with the active locations on the page by entering commands via a remote control device, whereby the system reads the meta-data and takes the action associated with the location. Actions include moving to other active locations, hyperlinking to other pages, entering user form data and submitting the data as a form into memory. The form data may be read from memory, and the pages may be related to a conventional television program, thereby providing significant user interactivity with the television.

Methods and apparatus for providing high integrity probability of connect fix (PCF) in GPS navigation applications, such as precision approach and landing and airborne refueling. In an exemplary embodiment, an enlarged pull in region is used to compute protection levels. In an exemplary embodiment, geometric extra-redundancy is used to enhance PCF and PAF (probability of almost fixed). In an exemplary embodiment, geometric extra-redundancy almost fixed solutions provide superior accuracy and integrity for GPS navigation applications.
