This application provides a mobile service upgrade method. In the method, each service kit in a mobile service is independently packaged into an APK based on a plugin-based idea, and then the kit is upgraded in real time when a user uses an application and the application invokes the kit. Compared with a full silent upgrade of the mobile service, this method shortens upgrade time and improves upgrade flexibility. Further, the APK of the kit includes a dependency relationship between the kit and a dependent kit, and the kit and the dependent kit may be upgraded together during upgrading. This avoids an invocation failure caused because a version cannot meet a requirement.

A method for distributing an application for an edge computing device performed by a computing device according to an embodiment of the present invention includes selecting a cluster including two or more edge devices from among a plurality of edge devices, distributing a first application to a second edge device included in the cluster, modifying routing information such that a service request incoming to a first edge device included in the cluster is transmitted to the second edge device, and replacing the first application running in the first edge device with a second application.

Methods and apparatus are provided for content delivery. In one aspect, a method in a device of receiving Adaptive Bit Rate (ABR) content comprises receiving an ABR manifest associated with the content, the ABR manifest describing segments of content and specifying a plurality of policies and respective associated data transfer rules, receiving an indication identifying one of the policies, and requesting segments of the content from a content delivery network in accordance with the content delivery rules associated with the policy identified by the indication.

A system and method for selecting a user profile for use with a platform based on an optimal persona of the user includes inferring a context of a user based on data received from a plurality of data sources, determining a persona of the user according to the context of the user from a plurality of user personas, and selecting a user profile associated with a platform that corresponds to the persona, in response to detecting that the user is accessing the platform.

A server includes a data cache for storing data objects requested by mobile devices, desktop devices, and server devices, each of which may execute a different configuration of an application. When a cache miss occurs, the cache may begin loading portions of a requested data object from various data sources. The cache itself may be divided into multiple partitions, and each of the partitions may be assigned to a specific attribute, such as an application configuration. Portions of the data object may be loaded into corresponding cache partitions based on the attributes of each. Although part of a single cache, each of the partitions may be independently assigned different cache replacement policies. Performance metrics for each of the partitions may be monitored and used to update the cache replacement policy for each partition at runtime without interrupting response traffic.

A system, process, and computer-readable medium for updating an application cache using a stream listening service is described. A stream listening service may monitor one or more data streams for content relating to a user. The stream listening service may forward the content along with time-to-live values to an application cache. A user may use an application to obtain information regarding the user's account, where the application obtains information from a data store and/or cached information from the application cache. The stream listening service, by forwarding current account information, obtained from listening to one or more streams, to the application cache, reduces traffic at the data store by providing current information from the data stream to the application cache.

Methods, systems, and devices may be used to support freshness-based processing of requests. Freshness-based processing may involve the service layer examining the age of stored content (e.g., resource representation) that it hosts and determining whether it is fresh enough to satisfy a retrieve or discovery request with a specified freshness requirement. If not fresh, the service layer can contact an application to refresh the content. In addition, freshness-based processing can also involve the service layer examining the semantic state of a command oriented update request to determine whether its state is fresh or not with respect to prior commands processed by the service layer. For example, the service layer may compare stored content associated with controlling a particular application (e.g. door is locked) and against the semantic content of an update request (e.g., unlock door) to determine whether it is the same (e.g., stale) or not (e.g., fresh). If fresh, the service layer can then re-target the update request to an application to have it perform the command (e.g., unlock door).
