Abstract: Embodiments of the present invention disclose a network switching method, a version upgrade method, and a terminal device, which relate to the field of communications technologies. A terminal receives a user instruction that instructs the terminal to access a network of a target operator. If an operator of a network currently accessed by the terminal is different from the target operator, a preset file is read to obtain image information corresponding to the target operator. A target image file corresponding to the target operator is obtained according to the image information and version switching is performed according to the target image file. The preset file includes image information that corresponds to all image files of operators stored in the terminal in one-to-one correspondence.

Abstract: A method for transmitting contents and user's interactions among multiple devices is provided. The method includes determining a group of object devices including a portion of the plurality of object devices, transmitting the data to the object devices of the determined group, receiving confirmation information from the object device which completes receiving of the data, among the object devices of the determined group, determining a clone device based on the received confirmation information. The transmitted clone information is used to transmit the data from the determined clone device to at least one object device which is not included in the object devices of the determined group among the plurality of object devices.

Abstract: A method and system for secure download includes generating a path to a location where a downloadable object is temporarily stored. The method can include receiving a request for a downloadable object, generating one or more unique identifiers, creating a path to the requested object using the unique identifiers, storing a copy of the requested object in a temporary location indicated by the path, and returning the generated path to the requestor. The method can further include receiving a path to a downloadable object and, responsive to a determination that the path is valid, returning the downloadable object. A generated path can be rendered obsolete and its corresponding file removed from the temporary location after a predefined time interval has elapsed. A database of the generated paths and associated files may be periodically checked, and those paths and files that have been stored in the database beyond a pre-definable expiry time can be removed.

Abstract: A system for controlled-tuning path performance data collection is provided according to group membership controlled using a tool or application. In an embodiment, criteria may be established for groups that are populated by member objects that satisfy the criteria, and performance data collection is performed for such criteria groups may be turned on or off from an interface of the tool. The tool may automatically update group membership and performance data collection characteristics according to user controlled settings but without requiring further user intervention during the updating. The described system may thereby be advantageously used in connection with management of performance data collection based on a defined groups framework in which selected groups are created, based on specified criteria, that contain objects (e.g., hosts, arrays, switches etc.) for which performance data should be collected.

A method comprises determining usage data sources corresponding to one or more clients of a computing infrastructure, and assigning values to client classification categories associated with a particular client based on metrics obtained from the particular client's usage data sources. The method includes generating a recommendation mapping between values of the client classification categories, and one or more resources of the infrastructure, based at least in part on resource classification information. The method further includes allocating at least a portion of the one or more resources to the particular client based at least in part on the recommendation mapping.

Abstract: The disclosed embodiments include a method, apparatus, and computer program product for improving network monitoring. For example, in one embodiment, current inaccuracies due to the imperfect counter frame injection error between ingress counters and egress counters is eliminated, by monitoring, using an ingress counter, for a time period that is slightly greater than the time it takes for a packet/frame to pass from one end to the other, for “no packets/frames”. In one embodiment, once this no packet time occurs, a signaling event is triggered. A notification is sent from the start of the path counter to the end of the path counter to start counting. A “stop counting/restart counting” signal is then sent from the start of the path counter to the end of the path counter the next time that no packets/frames are observed for the same period.

Abstract: In embodiments, apparatuses, methods and storage media are described that are associated with support for leap seconds for provision of media content. In embodiments, a leap second is identified for a time during which media content may be timestamped. In embodiments, timestamps may be generated so that no segment of the media content contains a repeated timestamps and the media content is provisioned. In embodiments, content may be provisioned using a non-repeating time standard, such as TAI, and segments of media content maybe defined to have different lengths. In other embodiments, different time standards may be used, but seconds may be repeated across segment boundaries. Other embodiments may be described and/or claimed.
