Patent number: 12299452Abstract: 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.Type: GrantFiled: January 10, 2022Date of Patent: May 13, 2025Assignee: Cisco Technology, Inc.Inventors: Thomas Vegas, Domenico Ficara, Anirban Karmakar, Giacomo Trifilo, Amine Choukir

Patent number: 12301569Abstract: Techniques are described herein for implementing and using a secure access service edge (SASE) exchange system to allow SASE providers to share SASE services with other providers. A SASE exchange system may be used by any number of SASE providers to support SASE roaming by user endpoints between different SASE providers. A user endpoint may use SASE roaming to access additional sets of SASE services and capabilities that cannot be provided by a home SASE provider and/or other current SASE provider(s) of the user endpoint. In some examples, a SASE exchange system may be used to transition user endpoints from one SASE provider to another. Additionally or alternatively, the SASE exchange system may determine a combination of SASE providers that can be used to provide different subsets of shared SASE services/capabilities to a user endpoint.Type: GrantFiled: October 28, 2022Date of Patent: May 13, 2025Assignee: Cisco Technology, Inc.Inventors: Sebastian Jeuk, Gonzalo Salgueiro, M.
