Abstract
This disclosure describes techniques and mechanisms for providing an automatic and lightweight solution to detect and resolve session stuck failure(s) due to erroneous anti-replay packet drops in SDWAN networks. The techniques may operate in a data plane of the network devices, such as part of an anti-replay feature. The techniques may enable a sending and receiving edge device to communicate via secure tunnels. The receiving edge device may detect an out-of-window error and may generate and send, within the data plane, a message that includes a set control bit to trigger the sending edge device to perform a synchronization and recovery process.
