Abstract
This disclosure describes techniques for performing a remote front-drop of data for recovery after a pipeline stall. The techniques include using a receiver-side dropping strategy that is driven from the sender-side. Components of a pipeline determine whether a pipeline is operating within specified latency constraints (e.g., experiencing a pipeline stall). Upon detecting a pipeline stall, the sending device is notified of the stall. Once the sending device is notified of the pipeline stall, the sending device can determine what action(s) to perform to address the pipeline stall. For example, the sending device may instruct one or more components of the pipeline to discard already sent data that has not been processed. This allows the older data to be dropped on the stalled pipeline while keeping the more recently sent data.
