Abstract: Methods of managing a fleet of devices are provided, as are methods for configuring a standby device for a job in a workflow environment, and methods for performing a job in a workflow environment. Device information is analyzed, such as information pertaining to verification systems. Device instructions are sent to various locations on a device network in response to a deviation from a parameter value having been detected. The deviation from the parameter value may correspond to printed media and/or indicia produced by one or more devices. A workflow device and a standby device are provided, and the workflow device sends configuration data to the standby device. The standby device installs configuration data and is introduced into the workflow environment.

Abstract: A system identifies a significant communication from a revived contact. A user and the contact interact, and the interaction is monitored to determine a weighted significance value to attribute to the contact. The interaction may include communication, a designation of significance by the user, and organizational associations. The weighted significance value is attributed to the contact. A subsequent communication is detected and a weighted time difference value for the subsequent communication is determined. If the subsequent communication satisfies a significant communication condition, then the subsequent communication is designated as a significant communication.

Abstract: An available bandwidth measuring apparatus classifies, into one group, a plurality of virtual machines communicating with a physical node. Then, the available bandwidth measuring apparatus obtains available bandwidth measurements with respect to the virtual machines belonging to the same group by transmitting, to the physical node, measuring packets emulating each of the virtual machines. The available bandwidth measurements represent available bandwidth available when each of the virtual machines performs data transmission in a different time slot. Based on the available bandwidth measurements, the available bandwidth measuring apparatus determines actual available bandwidth of each of the virtual machines, to be used when the virtual machines perform data transmission to the physical node in the same time slot, and notifies each of the virtual machines of the actual available bandwidth determined for the virtual machine.

Abstract: A semiconductor device includes a plurality of IP cores, a plurality of storage devices, a configuration information acquiring unit that acquires configuration information for specifying a timing when the IP core accesses the storage device, and an allocation determining unit that determines the storage device allocated to the IP core.

Abstract: A method, non-transitory computer readable medium and storage controller computing device that receives a configuration change request for a storage virtual machine, the configuration change request including a configuration change operation. A determination is made when configuration settings for the storage virtual machine are locked. The configuration change operation is applied to the configuration settings for the storage virtual machine when the determining indicates the configuration settings for the storage virtual machine are not locked. A failure message is sent in response to the configuration change request when the configuration settings for the storage virtual machine are determined to be locked.

Abstract: A technology is described for detecting a failure of a primary virtualized device and failing over to a secondary virtualized network device. An example method may include generating a statistical model using historical data for network traffic that has been handled by a primary virtualized device. The statistical model may contain a functional state baseline representing a functional state of the primary virtualized device handling network traffic during a time frame. Having generated the statistical model, the functional state of the primary virtualized device may be monitored by calculating a network traffic metric for current network traffic handled by the primary virtualized device and comparing the network traffic metric for current network traffic handled by the primary virtualized device with a data point in the statistical model corresponding to the network traffic metric and the time frame for the network traffic metric.

Abstract: An improved IP video playback system for quicker access and better user experience during IP video playback is provided. Aspects of the IP video playback system allow a content service provider to provide quicker access to requested content items. When a user requests access to content items, an analysis is performed to calculate the lengths of time in which a portion of the content item can be downloaded, cached, and displayed and the corresponding size of that portion. The analysis may be based on various parameters. Once the analysis is performed and the portion is downloaded, playback may begin and the process may be repeated as necessary with increasing portion sizes until a predetermined portion size is reached, the user indicates a content switch, or the content item has been fully downloaded.

Abstract: A request is received at a local domain name system server (LDNS) from a client application to resolve a domain name. Responsive to the request a WHOIS information corresponding to the domain name is obtained, using which an age of registration of the domain name and a first weighted value based on the age are computed at the LDNS. A host associated with the domain name is accessed to determine whether a type of a service is configured at the host. A second weighted value is computed based on the configuration of the type of the service. A weighted score is computed using the first weighted value and the second weighted value. An action is selected according to the weighted score. The action is applied to a network component in a network where the client application is executing, to control a manner in which the client application communicates with the host.
