Abstract
Techniques are disclosed for mitigating lost state data for a communication session by a network device performing session-based routing. For example, in response to determining a first network device has not received packets of a reverse packet flow of a session from a second network device, the first network device sends, to the second network device, a first packet including first metadata comprising a first control message querying a health of the session. The first network device receives, from the second network device, a second control message requesting second metadata for reestablishing the session, the second control message sent in response to the first control message. The first network device sends a second packet of the forward packet flow including the second metadata for reestablishing the session to the second network device. The second network device recovers lost state data for the session using the second metadata.
