Dead Peer Detection (DPD) is a method of detecting a dead Internet Key Exchange (IKE) peer. The method uses IPsec traffic patterns to minimize the number of messages required to confirm the availability of a peer. DPD is used to reclaim the lost resources in case a peer is found dead and it is also used to perform IKE peer failover.

It is inside of me.
It is a stranger
yet once it was agreeable,
opening and closing like a clam.”
—Anne Sexton (1928–1974)
“Up a lazy river by the old mill run, that lazy, lazy river in the noonday sun.”
