This document describes the method detecting a dead Internet Key
Exchange (IKE) peer that is presently in use by a number of vendors.
The method, called Dead Peer Detection (DPD) uses IPSec traffic
patterns to minimize the number of IKE messages that are needed to
confirm liveness. DPD, like other keepalive mechanisms, is needed to
determine when to perform IKE peer failover, and to reclaim lost
resources.
