Abstract: In one embodiment, an agent executed by a device maps a packet flow of the device with a session of an application executed by the device based on execution information about the application that is captured by an operating system of the device. The agent determines, based in part on mapping the packet flow of the device with the session of the application, one or more adjustments for a packet of the packet flow according to an application profile. The agent forms an adjusted packet by applying the one or more adjustments to a packet of the packet flow, wherein the one or more adjustments indicate to a networking device how packets of the packet flow should be processed. The agent sends the adjusted packet as part of the packet flow to an external destination via a network.

Abstract: In one embodiment, a device executing an application estimates capacity metrics for paths between the device and a data source from which the device pulls data associated with the application. The device estimates a number of data requests by the device that must be pending with the data source to maintain synchronization with the application. The device determines an amount of capacity of the paths to be used by a packet recovery mechanism without causing congestion, based on the capacity metrics for the paths between the device and the data source and the number of data requests by the device that must be pending with the data source to maintain synchronization. The device requests, from the data source, use of the packet recovery mechanism for the data associated with the application, according to the amount of capacity of the paths to be used by the determined packet recovery mechanism.
