Abstract: Techniques for a Predictive Connection Manager Service (PCMS) to predict when client applications will send service requests to backend services, and proactively establishes connections, caches data, or takes other actions, to reduce latencies between receipt of and response to these service requests. The PCMS analyzes historical usage data for the client applications to identify usage patterns, and uses those usage patterns to proactively scale resources to handle service requests. The PCMS can be implemented as a pass-through proxy for client applications to reduce frictions for managing how users interact with backend services. For instance, the PCMS can install client-side drivers such that updates or patches for the drivers need only be installed on the PCMS rather than on each client device.

Abstract: The present disclosure relates to email synchronization methods and electronic devices. In one example method, an electronic device obtains an email identifier of an email. The electronic device sends, to a server, a first request including the email identifier. The electronic device receives a first response from the server and extracts the email and the structure information from the first response. The electronic device determines object identifiers of objects in the message body based on the structure information. The electronic device sends a second request to the server if information of a first object in the message body fails to be downloaded, where the second request includes the email identifier and an object identifier of the first object. The electronic device receives a second response from the server and extracts the information of the first object from the second response.

Abstract: Technology related to managing network services using multipath protocols is disclosed. In one example, a method includes intercepting a multipath protocol request from a requesting host for a connection to a service. The multipath protocol request is intercepted by an intermediary server. A target host different than the intermediary server can be selected to provide the service. A multipath protocol packet can be sent from the intermediary server to the requesting host. The multipath protocol packet can add a subflow of the connection using an address of the target host. The subflow can enable a path between the requesting host and the target host that does not traverse the intermediary server.

Abstract: In an implementation, a shutdown coordinator sends an instruction to a router to no longer assign new sessions to an application instance, where the application instance is to be shut down. The shutdown coordinator sends a request to the application instance to export associated sessions for handover to a new application instance. The shutdown coordinator receives an indication from the application instance that no further requests can be processed by the application instance since all associated sessions have been exported to an external session storage. The shutdown coordinator instructs the router to redirect requests to the application instance to the new application instance. The shutdown coordinator shuts down the application instance. The shutdown coordinator deletes remaining sessions of all associated sessions from the external session storage after a defined timeout period.

Abstract: The present disclosure relates to utilizing a content service system to improve selecting data sources that are used to retrieve digital content items in response to content requests. For example, in response to receiving a content request, the content service system determines to retrieve content items by either calling a lower-quality data source with lower computing costs based on the request having lower service quality metrics or by calling a higher-quality data source with higher computing-costs based on the request having superior service quality metrics. In many instances, the service quality metric is based on the user characteristics of a user identifier associated with the requesting device. By dynamically determining to utilize different data sources having different computing costs based on service quality metrics, the content service system significantly reduces the total amount of computing costs for retrieving and providing digital content, without hurting the user experience.

Abstract: A method for intermediary client reconnection to a preferred server in a high availability server cluster. The method includes monitoring a persistent connection of a logical connection to a preferred server to identify an unavailability of the preferred server, establishing a temporary persistent connection for the logical connection to an available server to replace an unavailable preferred server, prompting attempts to reconnect to the preferred server at intervals, and providing a connection switching pool and simultaneously re-establishing a persistent connection with the preferred server for the logical connection using the connection switching pool while terminating the temporary persistent connection to the available server. The connection switching pool and a main connection pool used by the persistent connection allow for simultaneously maintaining two connections to different servers in a same server cluster for the logical connection.

Abstract: Techniques for management of traffic in a network. The techniques provide application awareness in a Network Address Translation (NAT) system. In some examples, a first traffic is received at a first switch in a network from a first application hosted behind the first switch. The first switch identifies a first resource tag associated with the application from the first traffic. Further, the first switch identifies a first rule from the first resource tag indicating that the first traffic is to be routed through an intermediate device that performs network address translation. Moreover, the first switch transmits the traffic to an intermediate device, which perform NAT to translate the source IP address of the first traffic to a second IP address. Finally, the intermediate device sends the traffic to a destination device indicated by the first traffic.
