A networking device can use sync request packets to synchronize connection objects with a peer. Real or virtual flow misses occurring in the data plane while processing a network packet indicate that synchronization is needed. A virtual flow miss occurs when a data plane connection object is obsolete. A sync request packet containing connection metadata and the network packets is sent to the peer. The peer uses the connection metadata to create or update its version of the connection object then returns a sync ack packet that contains the network packet. Receiving a sync ack packet can indicate that the locally stored version of the connection object and the peer's version of the connection object are consistent. The network packet may be processed normally when the locally stored version of the connection object and the peer's version of the connection object are consistent.
